Had a 302 with Aussie heads, 2V heads with closed chamber. The Clevor "Boss 302".

I saw one guy running to separate fuel lines from regulator

How much money$ did it cost to make 500HP just in parts, not counting motor/work price.

2006 Yukon SLT 4x4 L59 motor "WHAT WILL 3,000$ dollars on the used market get me for HorsePower/Torque not counting install work." "And what is the best route for keeping it a RELIABLE daily driver with lots of instant get off the line power, dont care for top speed" Jesus Christ is King Lord Savior and God, Amen!

"WHAT WILL 3,000$ dollars on the used market get me for horsepower not counting install work." I have a 2006 Yukon SLT with L59 engine, I want to make at least 500HP to the wheels and more TORQUE than HP. What will it take to get this done and still be a daily driver and reliable. RELIABILITY is the #1 thing it MUST have. I want to run 11s with not only not removing any weight but keeping my sound system in it that adds about 300-400 pounds over the rear tires where my TWO 80 pound speakers sit. weight over rear wheels is needed anyways in a vehicle especially one thats daily driver so it wont have a insane suspension that will squat down. she needs to keep being a truck that can tow and travel across the country like she does now, I am going to put tens of thousands of miles on her yearly, at least 5-10k miles mostly highway driving.

Nivlac45 has amazing videos with everything you need to know about this platform and how a stock bottom end (from multiple different engine samples) can go up to 800hp at the wheels.

A more realistic comparison would be which engine makes more power per cubic inch!

Thanks Richard

I was expecting you to change the lifters without removing the intake but i guess if you had a tight lifter it would have been a fail anyway.

I always install the cam first. i also don't understand why most everyone does it last. So much easier and less hassle to do it with the block upside down. you can guide the cam through the block from the crankshaft opening without scrathing and bumping the cam bearings.

Does understanding the "Disassemble, Stephanie" reference make me old😂

Finally my Sambar will be worthy

Hej Richard. I have a 4 bolt 350 block with the 186 heads with the big 2.02 valve. Would this heads be good in making a 383. All the best from Denmark 🇩🇰

What about a turbo application would the adapters hurt it?

What’s your thoughts on the l96 engine

one piece you didn't touch on which you didn't touch on has nothing to do with the power numbers but wear characteristics and longevity. you get a better rod ratio, significantly slower piston speed, and gentler inertia transitions with the 4.8 crank. most times hot street car/drag car it doesn't make enough difference to matter but in a drift car or a rally car where you are commanding a significant amount of power high in the revs it can make a substantial difference

Richard. Since the EFI does not need vacuum to operate, what does the power curve look like on a dual plane vs single plan with EFI?

Just picked a gen 3 m90 up from the local pick and pull for $77 with an aftermarket 3.4 pulley on it, I have a 4.8 with an LS9 cam, do you think the 3.4 would do ok or should I opt for the 3 or 2.7 pulley?

I've always looked at the LT1 engines as nothing but junk mostly because of the optispark and lack of aftermarket support. However..... I've just purchased my friends old 94 formula and its my first RWD V8 muscle car despite loving cars since I was old enough to say "car". Unknown RWHP estimated 425 on high end. Probably makes even more torque seeing this here graph. And hole shots are its favorite game. 3800 Stall Yank converter Brodix Track eliminator Aluminum heads Unknown Springs Rockers and pushrods LT4 Hotcam. Rear Torque arm bar Drilled front Struts Hoosier 26 10 17 slicks. Stage 4 4l60e transmission. Ford 9 in with 4.76 gears and 40 spline axels and a full spool Stock intake and personally have NEVER tuned this car. Weighs probably 3990 at its LIGHTEST with me in it. Full interior with carpet and even has the spare tire in the back. Car ran 11.30 @ 121 MPH its first and only pass ever. will do on the street what it does at the track. This car would hook on ice. Its got more in it. I want to max out NA HP and get it to run 10.70 as is on motor then spray it. Couldn't give this car away on FB marketplace before I ever even sat in the drivers seat and by GOD I'm glad I couldn't! I didn't realize the stick shift world record setting Grubb worm Camaro was a 96 LT1 350 and its motivated me to push this car to its absolute limits. LS is my favorite platform but I'm personally going to set out to make sure this tired and ignored ole SB 350 is NOT overshadowed by it's bigger brother where im concerned.

How much will cost it cost to build a ls supercharge for my 76 nova with not to much money

will someone pay me to do this.... i have the time please call

not a very good conclusion.

if your gonna compare, shut up and compare. you said just lsa change , why show all the specs?

Richard, your preference? 1.) N/A 489BBC or 2.) A 408 ls with a whipple S/C?

First of all Appreciate all your content. Question for you Richard: would you say a BOOSTED larger Displacement Engine does not have the Reliability And Longevity as a smaller displacement engine? I’ve seen many larger 426,427,454, etc have issues after @ 50-60K miles. Where is the OEMs Ford, GM, Chrysler and even Porsche, Nissan GTR’s, etc all using for the most part less Displacement. 6.2L is the largest from GM and now 5.5L with the new ZR1. I’m sure these companies don’t want their engines falling apart under the warranty period... Just wanted to get your thoughts? Again, not for strictly racing at the Track but for Longevity of the Engine? Thanks Much

I have a stock 2001 camaro with the 3.8 . What would you recommend for an aggressive cam? I will be doing headers on it as well.

We got an L77 caprice. 119k Gathering parts for DOD delete. We have lifters, trays, plugs, billety valley cover. Thinking about the btr stage 2 v2 , 660 springs. Wanna guess our WHP? Also, should we install a Melling 10295 while we are in there? Thanks!!!

But on LS2 how much is too much for the block? Ended up doing a LS2 / Ported LSA blower build in my CCSB 09 silverado 4x4. 222/245 116lsa, LPC LS3 255cc 11 deg heads. 14 psi and it made about 750whp/700+tq thru 20" wheels and 32" truck tires. awesome power and torque for a 365ci w forged rod and piston in a 6200lb truck. Love this LS2.

i can not find the follow up video of what ended up being the problem

I was of the understanding that the unshrouded of aftermarket over bore like 4.50 on BBC does see noticeable bump in power vs a notched factory bore. Too me it sounds like you saying more head flow better shrouding or no shrouding.

thank you for including some information for those of us that would like to add some power for low end and towing power

Hi Richard, I'm working on my 6.0L, 799 heads, BTR .553/.553 224°/ 230°, 109°LSA. Can this engine run 2 GT45's or are they too big? Would an S475 be better? I'm a little undecided. Looking For 800hp.

E3 plugs were recommended, so I put them in my car. No noticable improvement in fuel economy or performance. After 1500 miles and many misfires, installed the factory recommended NGK's. Mileage and performance increasrd exponentially. E3's are junk.

Any chance of you doing any boosted chevy 2.2 ecotec stuff

I just picked up a 05 2500 2wd 6.0 am lookingbfor parts now, wanna do as work as I can myself

Richard hello I'm asking if you could give us the timing your different combos like for reference to the different engines you test. I would like to see the difference your testing shows. Thanks

Richard love what you do! There's no doubt you are the ls king of testing! I know your reluctance to share timing on your tests, not sure why as it's no responsibility of yours what anyone does with thier builds. We always hear that timing is engine specific, different heads, different induction, different cams, compression, fuel the list is endless but you have the great opportunity to show us and give us a look at what all these combos are actually liking. Thanks for your time 😅 please consider this.

What about Comp cam 54-476-11 is it more aggressive than 54-469-11 .. is it even possible on 6.0 L98 Gen IV or is the valve to piston clearance going to be an issue ... I know we need dual springs such as Pac 1238X or 1237X with matching high load rocker arms to match the spring rate. Any recommendations?

It's not HP that kills that engine. It's RPM. The 289 imo can rev higher (safer) than a 302 due to the extremely short stroke.

So your car should be around .44 drag if we talk just the data lol I found a calculator that is probably not perfect but I think you may need 680hp to get over 200mph I think you need aero or boost lol

I think it will take about 600chp to go 200mph. 660 would definitely be enough.

If you look at the Stock Eliminator cars they have a later IVC which results in a longer intake duration and a (relatively) retarded ICL. This takes advantage of the inertia from the long runners. It's part of what allows them extend the rpm operating range of the long runner engines. It might be somewhere to look for inspiration when selecting a cam for a street TPI.

Richard, if doing an max effort NA build, and a boost build side by side, what size engine would you use for each? I currently have a 6.0 iron block, but if a 5.3 aluminum is better for stroker, is that a better NA base and using the 6.0 for boost?

at the rear wheels will a transmission lay down more power in drive 1:1 vs overdrive?

The big Oldsmobile, Pontiac and Cadillac motors surely could make a case, in stock tune anyway.

I remember when you bought that car. Phi Alpha, brother.

Hey, im currently building a LM7 with the plans of NA power at first before i can afford Turbo kit, what cam would i use for the NA that would also work when i apply the turbo kit later on? this is going to be a drift car.

You should be close to 200mph I remember seeing that wind tunnel information saying with a drag coefficient of .31 you need hp around 300-400 to go 200 but I’m not sure about what gears it would take.

Richard,a local machinest wants to put 4.125 sleeves in my 5.3 aluminum block. Will it hold up to 700 hp + 200 hp. hit of juice?

No idea how you could do this….but, I looked at a brand new generator yesterday made by Generac. I immediately went to the engine…. It has an 8.9 L V8 engine that makes 228 hp at 1800 RPM. It is a gasoline style engine with a carburetor, spark plugs, and a distributor. It looks like it might be modeled after a Dodge engine (based on the big barrel style intake - could be a GM design - distributor is in the back.) Almost forgot, 😂it’s also turbocharged with an after cooler. It runs on natural gas or propane. If you could get your hands on one of those and hot rod it with a cam and head work….that would REALLY BE “the other guys engine.”
