Here's What Happened to my F100's Engine... 

Be sure to grab one of the F100 Tee's for yourself! Proceeds go to fixing the motor lol... www.nineoninespeedcompany.com/

Hate to see that truck hurt. Personally this my favorite vehicle out of your fleet. Hopefully it’s gets back on the road soon Craig. Keep it up as always

Bruh- I'm an old guy in Huntington Beach. I been following your channel since you were in highschool. You owe no explanations to no one regarding this truck. It's effing rad! Keep being a Ford guy!

As a new viewer I can't wait to see this truck back up an running. The last video left me drooling for more. Sounds so freaking amazing. If it makes you feel any better I blew the motor up in my C5 Corvette earlier this year playing around with around 14 PSI of boost. It went lean for a reason we never really did fully figure out why, butted the rings in cyl 1 which proceeded to rip the wrist pin out of that piston which then broke the rod in cyl 2. Destroyed the block, crank, cam, oil pump, the blower, the intercooler, and a few other things. All told I am in it for about 10 grand my labor. Car is back up and running with a forged 408 and a new blower.

I love that you’re going through the process and learning. Figuring out what it can and can’t do and doing the work yourself. Built, not bought.

People I work often ask how I got so good at my job. I always tell them I have been doing it for 22 years and made every mistake you can. Best way to learn stuff if to mess something up. Those are mistakes you don't make again. Keep up it man, love the truck.

Love that you’re doing everything this way man! I’m learning things from you, I appreciate your posting all this info

If you’re putting a hydraulic roller and H beam rods, you might as well put forged pistons

If you are going to H beam rods, go with forged pistons, it just makes sense to put something in there that can handle you beating on it. You kinda drive like I do, and my engines are (usually) budget and they last decades. Put money where it does the most good. Also invest in an O2 sensor. I did so I can tune my carbs better on E85/E100. If you want reliable 7k rpm, go solid roller instead of hydraulic roller. The juice roller lifters are heavy, and more weight means you need more spring pressure to control it, you will hit valve float with a hydraulic roller. Bending pushrods is a thing when you float valves. You can get a solid roller with lift that will not bind using your current springs, or go ahead and upgrade them as well. Duration gets you the RPM. Also since you have a carb, I'd rock a 108 to 110 LSA, give your tiny engine some more midrange to go with the top end, plus the lope at idle is sick with a 108 or a 110. If you want to stop breaking engines and possibly ruining not so easily replaced parts (even sbf blocks are getting rare), build it with some longevity in mind. Sure breaking stuff gets views, people like carnage, but that can be tires, axles, and stuff like that too. Big heads and cam on weak pistons is clown shoes man. Make the bottom end robust, not just barely good enough. Take it from an old guy with a heavy foot who breaks stuff all the time... which is why I learned to rebuild transmissions, 600ftlbs in a heavy vehicle does a number on transmissions. Ask how I know.

I can’t believe that old 5.0 screams like that, sounds good as hell with the new exhaust.

Bro, this truck is amazing. I love what you did and the fact it's a true garage/driveway type build versus a shop trying to be retro with a $100K car budget makes it this even better.

Please check the tension on the rings. Overheated rings can lose sealing pressure. Finnigan was able to save his hemi by putting a new piston and rings in.

I have two '72 F100's; one with a stock 360 and the other with a mildly built 390. Love, love, love the early '70's bumpsides!!!

I agree you only learn by doing. So glad to see you doing things your way and not what others think you should be doing. That’s one of the things I enjoy about this channel. Besides the cool hot rods. Glad to see the fix for the f100 is not a big deal.

I’m not a ford guy but love watching ur vids and now ur making me have a soft spot for f100s and other old ford trucks

Engine builder here and wanted to say awesome job! Loved the fly bys, until she went down of course. The truck does sound awesome!!! Thought to myself Holy crap it sounds like the BULLITT! Don't worry about the neah sayers, sounds like you have done your research, build them for how you want to run them. Dodge fella myself, but know well the hi rev capabilities of Fords 302. Question on your hydraulic roller cam upgrade, is it capable of reving 7000 without pump up on those lifters? One of the reasons a lot of hi rpm builds stay with solids. Nice work BTW!

I have had 2 1977 F150 trucks and loved them both . The first one had 400 modified and the second one had a 300 inline 6 .

I was hoping it wasn’t something too bad, glad it was just a ring land and not anything spun in the bottom! Your idea for the new set up sounds awesome! Stronger rod and roller cam will definitely let her eat!

Great message. I think it's awesome you build it and learn from doing! Kudos for taking that on and figuring it all out.

Just found your channel and watched the last F100 videos and I‘m blown away by the videos you make and especially by the sound your F100 makes 🤤🤤🤤 What a Biest 😍 Glad the damage wasn’t that bad, in the last video it sounded pretty much worse. Will watch a bunch of your older videos and of course subscribed to your channel 👍 Kind regards from Germany 🇩🇪, Philipp 👋

" While you're in there"... Been there, Craig. You are so right about doing it yourself - we learn by doing- and NOTHING beats the feeling of having done it yourself... And then beating the shit out of it.

Experts had to start learning somewhere and you are doing it your own way. Keep up the good work!

Love the truck and love your outlook and your thirst of knowledge and the fact you’re doing it all yourself! Keep it up and I can’t wait to hear this little beast rippin soon!

You are exactly correct, this is how you learn! I will be so happy when you finally build an engine that can stand up to your right foot! 🤣🤣

Keep pushing Craig, keep doing what you love. I know that truck will be back up and running, putting a smile on your face in no time. You’ve been a huge inspiration with your truck for my current project, I’m going thru the process of building a 307ci SBC for my ‘91 S10. My goal is to have it rev to around 8500 with a really great set of Aluminum heads but I’m still researching for some of the right parts I want to determine my ideal compression ratio.

WOT pull was amazing! Sounded like a beast. Good that you are working on that yourself and NOT having a "professional" (who also occasionally has to learn things the hard way) build your motor.

I’m super glad you made this video dude. I have a 76 dentside I’m building a very similar engine to yours with. I have a 600 carb and pretty much the same exhaust as yours. I do have a 750 that I’ve been debating on running when I got it back together. And this solidifies it. Only difference is I have ported iron heads and a roller cam

Thanks for the in depth video. It's helping me diagnose a similar situation in my truck with a broken piston from a lean condition. Although mine doesn't spin as fast or sound like your truck

Craig, live and learn. Haters will be what they are, WOULD BE, WANT TO BE's. Get it done and go on, you are doing great. Hell, the first engine I built put #3 piston through through the block. Tons of fun. Keep up what you are doing, we wouldn't have it any other way. 👍👍👍👍👍👍👍

13:09 FACTS!!!! I can't agree more! I have learned the most from trying and failing. Bless you man!

I had similar setup on my old mustang but I had trickflow high port heads. I went from a 600 to 750dp Holley and got jets adjusted and it made a world of difference.

Thanks Craig. I really enjoyed this video, I learned a lot. My old truck is governed to a sad 2600 rpm.

Where’s the crew cab? I can’t wait to see more on that again

Its just so crazy to see how far this truck and this channel has come, i remember when he was hitting his highschool drags in this thing stock asf

New to the channel, that's an insane truck, can't wait to see more of it.🤙🏻🤙🏻

Just makes good content for a future vid. I've blown motors & tranny's because I just didnt know how to match upgrade components .. I burned the valves on a 72 Mustang with a 351 Cleveland.. I opened up the exhaust & dumped it mid way of the car .. It couldnt get rid of the heat & burned a couple valves... I blew an engine dumping ATF down the carb ! I put a shift kit in a Mustang Cobra & it cracked the tranny housing... Upgrades tended to bust sht...I learned you gotta match upgrades with upgrades.. Anyway , it always gave me an excuse to make it better/faster.

Sick build bud, I can respect someone who works on their own projects otherwise if someone else does it for you it’s their project. As they say out here in Oakland CA all gas no brakes.

Hi Craig, That is amazing that it is only one piston and that no other major damage occurred. Have you asked yourself why that cylinder and no others? I wonder if the intake/exhaust port to that one cylinder outflow the rest? Something to think about. Check out Microblue for the bearings and high friction areas and Thermal coating the piston dome, combustion chamber, valve faces, and exhaust ports.

Not terrible news, just some work, and good plan to upgrade to better parts while your at it! Fun truck, sounds fantastic! I had one like it many years ago, except I dropped a 429 SCJ in mine. 😁

got in on the t-shirt drop. had to contribute to the rebuild. looking forward to hearing the new motor a 7k rpm. major days-of-thunder-leaving-the-pits vibes

Great video Craig. Lots of explanations given. Honestly I thought you were over revving it. But after watching this video and hearing your cylinder head specs, I agree with you. You found the issue pretty quickly and I’m looking forward to seeing the new setup on this. A roller is going to be great. I’ve converted my falcon and my mustang to roller and it’s one of the best moves I could have made.

This truck is awesome! the sound is incredible one of the best v8’s I’ve ever heard let alone in an f100! Keep up the good work dude

Anxious to see and the the truck run again. It sounded amazing running through the gears!!!

Thank you for sharing and the appreciation to your subscribers

I think you just need a louder fuel pump!! It did sound great for those pulls, looking forward to more!!

I’ve had the same issue in the past with breaking 1 maybe 2 pistons and limped back to the house… i usually have extra pistons etc laying around so i just drop the pan and pull the rod caps, pop off the head on the problem side and swap the bad pistons out, check the head on the bench n slap back together and boom good as new. I’ve done it in a day, these small block fords are incredibly durable and very forgiving.. my truck is carb’d but i have an air flow meter on it lol.. right now I’m running a 302 small block nothing special just flat top pistons , mild cam, holly 600cfm 4 barrel carb with vacuum secondaries and msd ignition with long tubes and twin 40’s.. it runs great and the mpg is pretty good considering it hauls my 5,800lb truck around everywhere with whatever shenanigans I’m doing..

im glad i found your channel! Fire! Always will be watching

I don't know how this dude hit my algorithm again. I remember watching this truck when he was in highschool with it. Never the less glad he's still at it, and the truck has come along way.

2nd video watching on this channel, digging the way you explained what broke down the process of how it functioned. Easier to learn this way you got my subscription.

Very interesting video. Sorry to see this happen. Love the truck, though. Great educational experience, overall.

Love the channel, always transparent with the viewers

Weird did the same thing in a 351W with KB pistons...around 1996. I waited about 6 weeks for the piston...glad the turn around time is improved. BTW I ran the car for about 2-3 days...my engine builder (dad) was amazed the cylinder was fine 🙂

Kool work man. I have a 1970 302 stock everything bottom end!, with twisted wedge heads and a ford roller Z cam ,spun it 7,800 rpm on the street daily for 5 years before I pulled it for a rebuild

I've got a 5.3 with ss2 cam and 7875 turbo... I've blown it up 2 times due to fueling issues with carb. I now have 4 mahle stock spec pistons on driver side that replaced the pistons with broken ringlands. And the passenger side still sports the original 180k mile pistons. Truck runs great now with Holley Terminator x. Have 2 years on this setup up since last blow up lol

First, love the channel & the projects! long time Ford and fox body guy - I see some accurate comments in that the piston broke not melted so I would think ring gap for those KB's wasn't quite enough. The KB's are an ok street piston, not a fan of the huge accumulator groove design - a decent forged SRP/Wiseco/DSS forging is where you need to be, based on how you use this thing it's honestly beyond what any decent engine builder would recommend for a hypereutectic piston. if you can spring for it a Mahle Power Pack setup and a good I beam bushed rod would be sweet. also, a small solid roller is what I would recommend for that setup - 236/242 @.050 on a 112 LSA- mid .500" lift, a good 1.3" diamter LS style dual valve spring and bushed lifters. cannot wait to see it!!

Awesome man good see you got it under control . I know you will build back better !

Honestly I think building the bottom end now and going to a 306 build would benefit your application. It's a fun high reving bottom end, very forgiving and loves boost also prochargers are a great add on to a 306.

Awesome truck. Saw the "break" clip on turbo king. That's how I ended up here, now I'm sucked into seeing how this build continues on. 👍👍

Inspirational, I salute you. You kindle my passion for Motors

Sounds great! Keep learning, you sound pretty smart to me!! Good luck!

Why not upgrade the pistons while they are all out? Love the content

Back in the day when we had decent fuel with lead you only had to look at the tip of your exhaust pipe to get a reading of how your motor was tuned .. If you were running a nice grey pipe you were usually spot on

I’m a 351 W fan myself and I’ve got a 360/390 plus a true 427 Ford but anyway glad too see that the block is still good over fueling is better than under fueling learned that a long time ago

The Black widows definitely have a signature sound. I have them on a budget built SBC with a comp cams XE274, dual xpipes and venom 250 mufflers and it’s idle sounds nearly exactly like this. Sick fucking truck dude! 🤘

The new exhaust definitely sounds awesome! I’m ready to see the F150’s 302 come back to life again, even stronger!

Doesn't matter now but when piston engine aircraft get built or rebuilt they always log the weights of the pistons, pins and rods. Then if there is an issue and a piston gets damaged, you can just get a replacement piston of the same weight. Love your F100.

That thing sounds wicked,awesome exhaust

Can't wait to see the new parts going in the motor

Always build it vs buy it if you can. This process of learning by doing is fantastic and thanks for thanking the time to document and discussing the work, successes and failures.

not gonna lie I never saw any of your content until I watched the previous vid, and I assumed you had no idea what you were doing based on the lean condition and you being unsure what happened at the time. glad I saw this explanation though and I love the truck, nice to hear you are gonna fix it yourself and do a few upgrades. I subbed, can't wait to see

Let's do it! Upgrades are exciting for sure....Don't like the reason why lol...But might as well put her back together better than ever bro! ❤

Forged Pistons are your friend. I built a 428cj that with the cam I put in it would easily rev past 7200rpm. It had domed 12.5 trw forged Pistons and shaved heads so compression with steel shim head gaskets was about 13.7 to one, so racing fuel was a must. Had roller rockers and solid flat tappet. Mallory ignition and melling high volume and high pressure oil pump. On top of factory Cobra jet intake was a 750 cfm Holley double pumper jetted up. Didn't have an Air/fuel gauge but looking at plugs and running correct heat range ultra important. Glad you didn't break it worse but I do recommend forged Pistons for any motor that is twisted anywhere near 7000rpm.

Looking forward to seeing the upgrades!

Great diagnosis. Hope you get him back on the road soon.

Just found your channel. I love these trucks. I just sold my 71 that I did the crown vic swap on. Never got around to putting the engine and tranny in and the guy didn't want those (he was going 5.4L). Fresh 460 with a built up c6. Not sure where abouts your located but I wouldn't mind letting it go if you want to hop on the bigblock wagon.

MAN, I saw those passes. It was PURE UNALTERED GLORY. I love hearing a "small" V8 scream it's lungs out. Looking forward to more crazy shit. 👌🙂🤘

Nice to see the younger doing this love your truck

Things happen for a reason Craig , I can’t wait to see and hear the new improved super motor . Will you run it on the dyno afterwards? Cheers

keep doing this my man, i can listen to you talk.. im learning.

i love seeing you beat on your stuff that is what it is for great stuff thanks

When you put a new piston in it, make notes of the piston weight so in the future if you have a similar problem, you will not have to pull it all the way apart to replace one piston.

Happy to watch this all go down!!

I wonder how’s his ford fox body is doin! Lowkey I only came to this channel to see what else he would do it! But I’m loving all the other videos too! Keep it up man! 💯💯

Thank God I subscribe to your channel Craig! I almost broke my brand new 408 Fox by doing the same thing with my exhaust. I only had a little 650 holley on it and was getting ready to hit the street for some high rpm runs, but had a few oil leaks so quit for the night and watched some of your videos thank goodness! By the way I'm 80 years young been racing Fords since 1957 and learn something new every day. Thanks to Thecraig909, keep it going and good luck. jimmystang

I'm sorry that happened, I love the build even tho I'm a Bowtie kinda guy. But definitely a good lesson for anyone including myself to consider and definitely adding an AFR meter makes it sooo much easier and fool proof. Can't to see her ride again!!!

Damn brother hate that happened. The same thing happened to me a couple years ago, I had those Keith blacks in my 302 in my 76 ford truck and it broke on cylinder number one so I pulled it out and rebuilt it again with sealed power and never had another problem. Good luck.

Subbed. Love the way you drive, and your whole ethos of drive what you build, actually.

Just subscribed! I love the truck man. I gotta 76 f100 sort bed with a 390 that was my grandfather that he just gave me and I NEED to start working on it

I never heard you say what you were going to school for but I'm sure it's some sort of engineering you keep it up the way you're going you're going to be an engine builder and tuner for a Pro Stock NHRA team

Love them FORDS! Great content man- new to the channel!

Yeah man! That follow up and your info is getting you a like and a share with subscription.

Looking forward to seeing the roller setup. Build it back better. 👊

Doing a great job you done a normal thing when racing in 70s and 80s I broke four motors in one summer to run under a national record but I started to win and it was a 69 mustang with a 302 your learing and it feels great when it works

Hey way to keep on learning have to pay to play and on the way you learn keep up the good work my friend!

What a bummer....You will get it going again...Looking forward to it.

Sounds amazing love the videos!

Thank you for another most excellent episode!

You will rebuild her and she will once again be a wild beast! Improve her and upgrade , as well.

Keep it Ford tough and do YOUR thing. Great ideas in your last two minutes...do the upgrades!

Your learning a shit ton doing your own work, personally I love it. If money wise it don’t hurt and you’re not walking have fun,gives us more tube time!
