DIY, EASY BASIC BOLT ONS-5.7L LS1 MODS 

Glad to see the 5.7 getting some love! Guessing a whole lot of us would like to see more on boosting one. What's a safe hp level? What should you gap the rings to? That sorta stuff

USA guys like the 5.7 to. Love seeing these. You have helped a lot of people. Thank you

I watch every new video of yours while I eat my lunch, every single day. I can’t get enough of them!

I'm always impressed by the factory truck intake when compared to these $600+ intakes

Great job on the playlist man. So so many RU-vidrs, in fact most of them forget to maintain them later on. Or they never properly set it up in the first place. PLEASE stay on top of that playlist it will further set you apart. Seriously set you apart in fact, lol and it’s so sad that thats true too.

Excellent episode. Thanks for doing this one. I’m an Aussie and I’m going Turbo LS1 your testing is guiding me hopefully in the right direction. Thanks Richard. Support from South Australia 🇦🇺

Been waiting for this one, thanks Richard!

🤘🏼 Straya says. Cheers mate 🤘🏼

As always , another great Video from Holdener

Been waiting on this to drop, Thanks Alot.

I'm glad to see a set of RHS heads on the dyno...I'm about to put some on a 6.0 with a BTR Stage 3 cam & a 4.000" stroke 😉

Aussie here. Thank you, Sir ✊

I also have been waiting on this 😎 you are the man I have 04 gto ls1

Thanks for the video I needed to see this !

YES! My 99 SS will get some love now!

like always you are great with the ideas and amazing explanations, thank you,God bless.

I have been waiting on this!! My gto is needing more power and I’m not doing an engine swap till my LS1 blows.

love this.....one day ill build my 2002 LS !!

Would love to see the stock intake numbers for the LS1 (I know its in another video but would like it here for a baseline)and then a comparison to the 90s LT4 that it replaced.

Bored a cast iron boat anchor 5.3 to LS1 spec for sh*ts n giggles. We'll see how it all pans out. Nice to see a LS1 video. So much great information in all your videos. Thank you.

Best channel ever!

Just picked up a low mileage LS1 and have been curious about what it's potential is, thanks!

Hey Rich, I’ve seen all these different V8s... I’m still waiting for you to do a 1UZ series. NA, ITBS, giggle juice, and all sorts of FI. SC, single Turbo, and twin. Looking forward to it

5.7's & 6.0's here are the most common, 6.2's are like Rocking Horse Poo!

Richard Ebay has a new turbo it's a 78. 76. T4. Billet wheel. Stated to make up to 1000 hp. They are 280 bucks. Everybody better get a couple before this gets out. Be great if you could test them as a single and twins. Great job.

Thanks Richard 😊

Can't wait to see the ls6 content. My bolt on 2002 ls6 made 451whp/423wtq on pump gas.

Thanks for everything richard rs

it would nice to see you do a cylinder head comparison from the cheap Chinese stuff to the name brand stuff i hear mixed reviews about the cheap Chinese stuff

LS1 today? How about an L33 block bored to 3.900 or so, then add the components of your choice. Of course if you’re adding boost (a lot of boost), then don’t bore it, just turn up the boost controller. That first head upgrade example seemed extreme. A 212° intake cam making 529 hp at 6500? I’m hoping my 6.0 cracks 500 hp at the crank with a 225° intake lobe and 823 heads. Of course part of the difference is the 9.6 or so compression of the LY6. Still interesting info, thanks Richard!

I would love to have a asmr of high revving engines back to back with descriptions of what brand in the dyno

Richard , any "guestimate" what adding 1 point (say about 11:25-11:1) of compression would do to the engine with the cam , intake , heads & proper tune ? Thanks for all the cool stuff you do !

Yes, the OG!

I have a 98 Camaro w/ an LS1 in it.. I have Headers, Y-pipe, (cats removed) & SLP Cat Back Exhaust.. K&N Cold Air intake.. I had it dyno tuned, but my HP to the rear wheels was 310HP..

All of this info was available in the late 90s and early 2000s. Budget combo? Ported 243/799 heads, LS6 intake, throttle body, cam, headers, injectors, tune...let it eat.

Hey my man love the content truly I do but what do you think of the L76 6.0L v8 in a g8 gt and what are some cheap cams to boost the power

If I remember correctly, here is the USA, f body ls1 enginges started coming from the factory with the ls6 intake in mid to late 2000.

If you make these kinds of mods and get these ~500hp numbers with a sensible tune - is it a reliable build? Or is it going to be in the shop all the time?

The LS1 I'm currently swapping into my jeep I grabbed from a wrecked F-Body at the Monrovia PYP, If I had known you wanted to test with an LS1 I would have gladly loaned it to you. It currently has 799 heads, with a BTR stage 4 cam kit.

Ahhhh yea you finally read my mind thank you!!!!

I'm trying to get my car registered with a c5 engine before i increase the power, I'm glad there is still a lot of power to be had out of the 5.7

What would you recommend for me to help my performance on my 1998 Chevy Silverado C1500 5.7 v8 all i done to it was put a cold air intake in it

Thankyou👍

I'd love to see an other guys for the v6 sho. 3.0 or 3.2.

Yeah yeah nar yeah cheers fella us Aussies love our LS1s

New to gm been big on Ford only 21 but I have 862 heads on my 5.7 fbody camaro it was a police interceptor that being said roughly how much hp would it make? Never took it in it see what it makes it’s my daily with 112k

Right on

I'm building a 5.7 out of a 4.8 since I have several 4.8's I figured why not.

Great video!! Can you please do an updated best HCI for the 5.7? 🤞🤘

what kinds of RPMs can a stock LS1 bottom end handle? i'm getting one ready for a Autocross car and often times we will bounce off the revve limiter for 2-3 seconds during our runs. i also plan on using a Torqy Comp 265Hr cam as well as mid-range power is very important for Autocross cars

Do the heads and cam upgrade on the Gen 2 LT1

HELL YEA!!!

The OG hell yeah

Hi Richard I enjoy all your videos , I have one Camaro 2002 with ls1 do you think ls1 is good idea for a single turbo or it is better a 5.3 ?, regards from mexico

I did not see anything about the port volume or flow figures on the 1st design? RHS cylinder heads or the compression ration after the cylinder head swap. I just assumed due to the era they were cathedral ports?

I would choose the truck intake with a heavy truck or SUV for added low end torque say something with the weight around 4500-5500 pounds with the 212/218 duration comp cam giving you good torque 2000-5500rpm and strong horsepower 3000-6200rpm with stock to 2500rpm stall converter 3.42-3.73 gearing but if you have a car with a weight under 3600 pounds or less with low gearing 4.10 and a 3000-4000rpm stall converter it be hard not to choose the edelbrock intake comp cam 231/239 duration cam power from 4000rpm to 7200rpm with this set should be a monster even a single plane intake with a holley 850 hp carberator would be ok for me

Richard, what engine would you rather build and race. A Built sbf 347 or ls1? There’s a big argument and I’d like to know since I’ve watched all your videos on them

Australia.... Yeah boi!

@richard holdener can you plz do more 5.7l ls videos. I'm tryna decide whether to go 5.7 ls or 5.3 ls

Finally!!!!

How about the original VORTEC 5.7 L 31 ??? PLEASE ?? stock injection..... , Cam, BOOST... PLEASE??

Can you do a video on taking a gen 3 5.3 block bored over to a 5.7 an do Dyno run on them.

Wondering if you got your hands on the BTR intake or the MSD intake on it..??

I was wondering what would happen if you ran a single turbo on an ls without a y pipe? One bank of cylinders goes to the exhaust as normal and one bank powers a turbo.

When boosted are these comparable to the gen 3 5.3s for strength? I get the blocks themselves are not AS strong.

What size n brand was the tb on the eldelbrock

Just got myself a 40k-mile LS1 (snuggled inside a 2001 SS Camaro) & I already love it.. but there's always room for *more* love. haha.

Genuine question... watched plenty of vids on LS’s, and would love your input. I’m currently on a 1JZGTE/ AR5 setup, and looking to get rid of it all and swap to an LS setup. Car: Built 240sx S13 I’m aiming for AutoX, Ima blow all my big bucks on a T56 Mag and twin disk setup, but on a budget for an LS setup pushing maybe 450whp, what would you recommend? Wanting to keep weight down so preferably an Aluminum setup. Genuinely curious.

any updates on the vortec 4200 build?

Here in OZ we have the opposite problem, all the ls1's but no iron blocks that make a millionity hp lol

I have a good 4.8 crank and 7 gen 3 rods and pistons if you want them I’m in Temecula

I commented and posted a link to my freshly rebuilt ls1 idling. For some reason it got deleted? I built that motor because of your videos and seeing the power potential of my engine.

👍

Can we get this same type of video on a l83 5.3

RICHARD GET TO TESTING WITH A LSA BLOWER !!plz

Finally but I'm not from Australia🤗

I don't understand how you get so much dyno time? do you work for westech, partners are you the owner? ****** ( I mean what is your relationship with westech performance group). could you make a video about this topic? just curious

LS1. Where it all started.

Hey Richard, I have a question; have you ever put a 5.7 (350) buick engine to the test? They are starting to get recognition and nobody really has put one to the dyno. Maybe you could try this one out?

The trade off is worth it if you're most interested in road racing and high rpm power for drag racing. I think its interesting to see cam only cars running 11s with a good suspension and converter, and ET is very similar w/ properly tuned stg 1.5-2 (22X duration) or a 23X/24X. So the peak power isnt nearly as important as the avg tq/hp in your launch to shift (racing) rpm range. I was going to increase from a 235/242 112lsa, mainly for more overlap(tighter lsa) and to get up to .650ish lift, but I'll be fabbing hot/cold side, adding a turbo from VSR or Sloppy, and then I'll prob want less cam in the 383.

What’s size rhs heads where these?

I picked up an ls1 for cheap. Had 4 bad rod bearings and the crank was damaged. Can I use a 5.3 crank and rods and have it balanced with new pistons? Thanks

No BOOST???

How are you Richard? hope all is Great. I am building a 5.7 now. I was looking for Rhs heads but I can’t find them. Is 243 heads a strong head? I am putting a car heads and intake

Hey Richard I got a question what camshaft recommend for ls1 5.7 stoked no spring change needs

A recipe where it focuses a ton of lowend torque with 93 octane or 95 Octane

What about the L76?

How much does all this cost???

First comment LS1 baby!

Can u put a pic of this truck intake where can I get one in oz

will you be tuning any normal car engine? Or you only do bus and truck and locomotive engines?

2003 5.7 liter big power upgrades on budget, any ideas and approximately the price if items and brand names

Where can I get a set of LS1 RHS heads. RHS doesn't supply them any more...

Ls1 5.7 with 862 heads? Any test with those heads?

Any word on if you're getting over to BTR anytime soon?

See out American vans have 6.0 and 4.8s. My own personal truck is powered by an 07 express van lq4. That said don't the aussies have rb30's in the wreckers?

So what’s a good modern cam for the ls1?

what?! you didn't try the best LS heads (706) on the LS1?

500 hp on any LS Vortec with just bolt ons ? Why would anyone rebuild a sbc or bbc when junk yard LS Vortec exist ? Power, reliability, efficiency & huge aftermarket parts support.

Me too
