Save the money on heads, run 706s to up compression and use a 238/242 cam for the same hp. Fly cut and run a thinner head gasket for more compression on e85 for bonus power.
Feel like this video shoulda been like a 3 part 20min a piece video. Showing each part installed and then dyno to see what each part made. But nah 3min of wacky waving inflatable arm man with a graph is cool
Did stock ls6 heads, Chinese manufactured intake with 102 mm throtle body summit stage 3 turbo cam at 226/230 .600/.600 lift at 113+4 lsa cam on my stock bottom end stock accessory long tube headered 02 z28 did 385 horse and 360 trq through a slipping clutch!!!
Accessory components rob power, not much but they do. I have a stock bottom end 5.3,862's with pac 1218's,sloppy stage 2 made 380whp, im also only running an alternator, and an electric water pump.
You make good videos very informative and comprehensive.. keep up the good work .. I have an ls but a lot of people have 96-04 mustang 2v it would be good content because them motors need a lot of help
I'm building LS1 5.7l iron block with forged eagle rods wiseco pistons shouldn't have any problem turning 528hp at the crank and I'm going to drop it in a 1971 international scout Comanche should wake it up a little seeing how the original engine is a 304ci 5.0l turned right around 215-220 hp
What’s crazy is how this crate motor which is the exact same that the 01, 02 Camaro SS and Trans Am has but it’s pulling 414 crank HP right out of the box which is roughly 350 whp. But the cars only put out 325whp even with the factory LS6 intake.
@@zacharyrussell6983 doubt it, they are running no accessories so the drivetrain loss once on a car with full accessories is higher than the standard 15% loss. Also most h/c/i LS1 cars dyno in the low 400-450whp range. My estimate is more on the conservative side but 460whp would be on the high end of the spectrum.
@@TheOhsemix true. I forgot about the no accessories. Yeah, 420whp is probably pretty accurate. Which to me just makes me feel better about my car doing 467whp through a 9” and 243 heads.
there’s mkre you can squeeze from the heads, i saw someone mention it already but running GOOD ported 5.3 heads to bump compression and running e85 to help prevent knocking would see you closer to that 450whp
This video references the LS1 crate from an early model Camaro, but power output "stock" does seem high, even with the long tubes and fuel management system on an engine dyno. The LS1 in C5 Corvettes made 350 crank hp in the later models with LS6 intake. Seems more feasible that it's an LS1 with vette cam, heads etc. Otherwise that's one seemingly generous engine dyno. I have an LS1 with similar cam specs, 232/236/113, ported 241 heads that flow bench tested better than stock 243s by a long shot. Kooks LTs and offroad Xpipe. Car makes 418hp 398tq at the wheels. Figure 475hp at the crank. No way that Fast Intake and 102 TB are worth 64 hp.
Good numbers for sure! My 02 SS with prc 2.5 5.3, custom cam and kooks headers made 426 rwhp. Swapping the ls6 for a fast might gain you 5-8 hp max but it's not really worth it. I have videos of mine if you wanna check them out.
@@bhcamaro2002 it’s pretty well known that that’s the typical range. I’ve had three cammed/ heads/ long tubes LS1 builds on two separate C5s (one built twice). All three builds with different cam specs and different porting on the heads. All were relative in power and torque at the wheels, give or take 10 to 15 hp/ tq. Three separate dynos I might add.
Question, being told that you can replace C/H but the car can't be used as a daily driver b/c it'll over heat w/o redoin radiators etc....what do y'all say
@richardholden I have a big huge question for ya ...... Why can't I take my 2000 mustang GT with the 4.6 coil on plug ignition system remove it and install a 5.3 LS engine I know the 4.6 has a 35 tooth reluctor wheel and the LS is 24/58 but I'm sure it's possibly to replace the 24/58 reluctor wheel with a custom 35 tooth wheel while I'm building the engine do you have any idea of the best way to attempt something of this kid I can't see how it's not possible
Those specs aren't far off from the Tick Torquemax Stage 2 cam. I have that cam in my C5Z and it put down 430/411 with the stock ls6 heads and intake. It's a great all around cam and it's awesome on the street.
Richard, why, how does the Early LS1 make more power at the crank than my 01 LS6 in my Z06? (385/385)? thank you. BTW, heading for teh Big 3 install after 20 years beating on this beast.
The dyno picture also shows an electric water pump and no accessories being driven. Your 385 HP is calculated with all accessories, including mechanical water pump, attached.
Probably 32/36 pounders. Texas speed has some decent deals on drop in injectors. Stock 01-02 injectors will make it close to 400 wheel. Some guys use the supercharged 3800 injectors for a little more.
I would actually opt for a slightly higher lbs injector for about the same price or slightly higher...say a 42 lbs or 48lbs injector to reduce the duty cycle on the Injectors (I believe optimal duty cycle is around 80%). More food for thought isn't just exceeding factory Injectors but adequate fuel supply so when running a Heads, Cam and Intake setup always be conscious of the factory fuel pumps limitations. Factory LS'1s had a 190 Lph so around the 450+ range you could be tapping out the pump. I recommend upgrading the pump to a 250Lph so you'll be fine till the 550rwhp range. Hell, might even consider a 340Lph if yiu have bigger build plans.
Hey richard, was curious if anyone’s actually ran the small bore ls3 heads, im trying to use them on my 383ci but haven’t found many people who actually ran them. You ever test them on a 5.7 ls1?
Those numbers should possibly be divided by a range of 1.12-1.20, which accounts for a 12-20% drivetrain loss. This gives a slightly more realistic number to potential RWHP. Example: 539 ÷ 1.20 = 449 539 ÷ 1.12 = 481 So there's a 32 hp difference, let's meet in the middle and say 16 hp and add it to 449 so that put it around the range of 465 RWHP. Obviously I'm not an expert but there's a pretty wide spectrum however I've heard many people being around the 450 RWHP range with Heads, Cam, Intake and a good tune on a 346CID LS1. As well, always remember if you switch out your rear differential for a heavier setup it will increase your drivetrain coefficient as it's more rotational mass the engine has to turn while transferring power to the ground.
Long tube headers and computer management. The Vettes back then made 350-360HP at the engine. Replacing the log style manifolds for long tubes and a tune could give 50-60HP.

LS1 with heads cam and intake will run 550hp. Throw in some dome pistons and you’ll grab another 20hp. If you’re losing 110hp getting to the tires, you got big problems.
Thank you for this video! Can you guys give a recommendation for heads and cam with a FAST 92 intake and throttle body? I have the FAST set up with SLP exhaust. Stock 2000 LS1. What do you recommend for heads and Cam?
The new RHS Pro Action Cathedral Port heads sound like a great option! For a cam recommendation, give us a call or send us an email so we can help you make the best decision possible!
@@pantherz2010 hey I didn't make any purchase yet actually still in Afghanistan for a bit. The Camaro is in the shop getting paint while I'm away. I'll try and keep you posted. So 243s/799 are pretty good option? I was reading online they are a good option even better than 241s that are worked
This was exactly my thought. I had a 2000 Trans Am with an LS1. During that time span, the factory power was 320 hp. That should’ve been between 280 and 290 on the dyno. And I’m being generous there.
@fuktheserbs the 350hp from the LS1 is crank already.. if you dyno a C5 it'll have like 300whp (roughly). Thanks for the comment though, yet i'm still confused. If the LS1 makes 414 crank, then a C5 would make loads of power on the wheels
Factory tests with all accessories, intake, exhaust, and tailpipes as equipped in the vehicle. This is optimized tune, 140 degree water, electric water pump, open exhaust etc.
@@DutchZombieSlaya Long tubes replacing log style manifolds and crappy exhaust on a 350ci motor will give around 50HP. He also has aftermarket computer for tunability, so the A/F and timing was dialed in even more than stock.
Ok Richard I got it even though my heads are ported freshly machined bottom end h beams and 11 to 1's still missing the intake the early model fast smart injection and the performer what get that magic number of 500 ,,,,but until I can go back into it ,,,it will be a fun strong running motor ,,,,,,sorry for the questions ,,and you've told us all about the big three many times ,,I thought I had it ,,,so i'm Happy and Thank you again ,,,you to kooL ~! SiR
Bob Button I’m H / C / I and have no regrets. I think it was pretty smart. I also did all of the work so I don’t have to pay for labor and my friend is a tuner so I’m good 😂
I'm thinking the same thing. And you have to rev it to get that power too. Considering that most of us retail buyers would have to add fuel pump, injectors, MAF sensor, custom dyno tuning, and have to live with that big cam at low rpm driving... the cost for this is knocking on the back door of a new SC kit w/intercooler.
To be fair, you could save money and run a ported 243 head and make identical power. I have pretty much the same set up with a Fast 92/92 and Cartek 243 heads. Made 467whp M6 through a 9".
@@wydopnthrtl and your car at similar power with the supercharger will be slower. Considering the added weight of the blower, then heat soak when running it over and over.
@wydopnthrtl Indeed. I've always been interested in videos like these before I actually got my C5 corvette. But after driving it for a few weeks on the street, I've noticed that I rarely EVER rev it past 5 grand. And most of these mods don't even kick in until then. Meh, I'll pass.
Depends on who tunes it as well. If they don't know what they're doing or just going for max numbers there will be a consequence. My tuner has fixed so many issues from previous tuners doing that exact thing.
You can't just find the price of a turbo on the internet and think that that is what a turbo system costs to install on your engine. It take some serious fabrication skills to do a turbo system in a Vette/Camaro and make it look good and keep fitment of the hood. In fact, it's one of the hardest mods you can do to your engine bay. You are far, FAR better off getting an A/A Supercharger system for 8k and its a simple bolt on with no fabrication skills necessary.
@@chevrolet355 Indeed you can. Installing them on the other hand... Well that requires knowledge, tools and time i dont have. Some cars are super easy to to. While my particular car, the C5 Corvette is one of the hardest out there.
@@m.2038 i know its impossible to reach more than 360 with stock ls1 even with a good tune if you search in google you will find that a stock ls1 will have about a 340 hp on the flywheel In the best case i dont know where did the 78 hp come from😂😂😂
@@chrisbryant1657 yeah a stock LS1 does not make 500hp a 98 LS1 makes about 250 HP the 2000 LS6 is also a 5.7 that one makes about 350 due to the heads and manifold
