A man named Sherman Sligh back in the 70's had a 600+ horse 300. Dubbed boss 300. It consisted of six segmented pieces of boss 302 heads, late 60's castings. For a half day or more straight he heated these segments 1200+ degrees and brazed them together.(cast iron doesn't play nicely in welding). He epoxied the intake runners(they were too big), put a massive thumpstick and valtrain to complement(roller lifters, cam, two piece pushrods etc.), along with custom rotating assembly.(gas ported forged pistons, alimunum rods,) Ran a 9.2 second qtr mile, vehicle type I have not found. N/a build. He mainly stuck to circ racing, eventually being banned. Even won indie by 2 seconds but didn't count as official record due to ban. Early 70's. I've a 300 myself, great engines.
My brother kept talking about building one to 600 hp. I thought he was full of bs until I went over to his house last week and saw it on the engine stand. He's serious.
Yes! Sweet Horse Pressure! (More Boost, & more head & cam!) That Power Nation 300 turbo build was an eye-opener & inspiration for us 300 I6 owners! We look fwd. to your new adventure!
I know I comment on your fb post already, but the DSS 390 ford pistons for the extra $80 to get the custom bore size so you're not stuck with a 0.050 overbore is by far the best route. Same pin size and compression height range. Those along with the Molnar 300 rods you're set with a good balance job. Looking forward to your build progress, hopefully will have mine running soon also
Updated ..I found a company that has roller cam compatible gears( i ordered 2). Also DSS Racing now makes forged pistons and molnar makes hd rods. Working on the roller lifters now.
Other people have said it, but I want to reiterate that you can use 390 Pistons instead of boring that much over. It's the best bet because the geometry matches up perfectly and you can keep[ your compression ratio up without creating even more work. I'm doing a very similar build for my 65 Mustang, so I'm excited to see what you come up with here!
@@bobadingo Not if you're building a bone-stock engine. He's building a 500HP 300, as the title of the video states. Stock pistons aren't going to handle that much power or compression. Obviously there's a reason to not use the stock pistons.
@@Freedomishere-im6ug Sweet! Always happy to see the 300 getting the love it deserves. I think it has the potential to be a bit of an American 2JZ if enough people start building them and getting the aftermarket incentivized to start producing more parts.
That pin/bolt that your door latches to: cut a little piece of air line about an inch long, split it lengthwise, and snap it over that latch pin. Your door will latch like brand new.
@@WastedPaycheckGarage oh, Pex! Good idea… I just wonder if it’s too heavy walled.. the OD is as important as the ID.. but I’ll definitely follow you and see how it works ✌🏻 PS beautiful truck, I absolutely love the 300 sixes
The most bomb proof motor Ford ever built. I had a 1980that ran over 500k. Abused by apprentices that got a free truck. U joints and breaks was all it cost over 25 years.
Best engine to ever come out of Detroit. Keep water and oil in it and beat the crap out of it cause she will take it and keep on coming. I bought one once suppose to been blown up. 32 dollars worth of rocker arms and push rods I drove it for years
I ended up going with some BBC H-Beam con rods, just a very light trim on the crank. I went with the longer, bigger pinto valves. Waiting on the machinist to finish the head to find out what pistons I need built. And yes H.S. rockers 👍 shooting for 600hp but will see, I'll probably push it until something breaks then build another even stronger. I'm a fabricator so I might just do the chopped up head eventually
Theres a guy that just did an LS headed 300. Big advantage to that is intake and exhaust not being on the same side. Good luck with your build man. Looking forward to it
Make sure you run a cam with the same profile for exhaust and intake meant for a power band of around idle to 5500 then size your turbo around 58mms to punch 500hp around 5k rpm with good tq in the mid low range
I have been working on a roller cam. Only issue is the distributor gear. I can't find anyone to cut a steel compatible one. You can take the bronze one and throw it into the trash. I don't want to replace it every 3 months!
What year is the replacements engine? Just to let you know the stock connecting rods are forged. All 240/300's came stock with forged rods. If you don't want to go aftermarket rods you can just add some ARP rod bolts and have the rods polished, shot peened and balanced. The early rods 1965-67 were slightly stronger because they didn't have the oil squirt holes. And they also had the smaller .912" piston pin diameter ( same as the SBF V8's ) . Which would allow you to run stock compression height forged 351W pistons. The later rods 1968-1997 have the .975" piston pin diameter. You can still run the 351W pistons but would need to have the small end of the connecting rods bushed down. If you really want forged pistons the best bet is to just have a set made. That way you can have them built to best fit your exact build. AutoTec are a good choice for custom pistons. You probably know this, but that cylinder head will also require push rod guide plates and hardened pushrods.
Damn I wish mine was 4x4. I just really have a hard time finding the motivation to build a truck that's not 4x4. I could build it, just to keep up with a modern f150 I guess but idk.
I had a 300 1996 with the automatic 4x4, I put a level and 33s on it. Mileage went down it got down bad enough that I could not enjoy it anymore for a daily. I think a 2wd is more badass, its 400 pounds lighter or so more power n mileage, less maintenance… All desert trucks are 2wd. Sold that truck now I might trade this chevy for another one its 2wd 5speed stick! cant wait to build it up!
Well I know this has been a year ago very good video and I got to ask you a question brother if you can remember where did you get those gauges at what kind are they good looking truck
I don't know how much it costs but Wiseco will make custom forged pistons and I've seen someone else on youtube order some custom forged 300 pistons from them so that could be an option.
Is there a strong reason not to go with forged FE pistons as in the Powernation build? I’m running the aussiespeed 2bbl intake, EFI exhaust manifolds, Holley carb right now. Thinking of doing a swap for an industrial 300 turbo/sniper build.
Nice truck love the sound clips! Q; what size exhaust you got?! Thinking of building myself a n/a 300 with those cnc promaxx heads I wish they had some in alluminium. Any other parts u recommend for a maxed out n/a 300? cheers!
FYI: "cold start" doesn't refer to the temperature outside, it refers to the relative temperature of the engine. it could be a humid 103 in Louisiana and if you haven't run your engine for the past three days, it is still referred to as a "cold start." And damn those mains are clean!
Unfortunately nothing to update on right now. Slowly collecting parts, luckily since I’m moving so slowly DSS came out with forged pistons specifically for the 300 before I ordered other ones. I may have found a local engine builder to do the machine work for me/help me assemble a good combo.
