Looking for everyone's thoughts on what would be a good reliable setup for 450-500whp. Have stainless 1 7/8 headers and y catless y pipe. Looking to change heads, cam, intake, throttle body, and MAF. Would also in a few years like to supercharge car, so would want something friendly with that. Don't look on using over 7-8 lbs of boost.

Plus I'd do one of two things....keep your stock MAF, or ditch the MAF and run speed density...I would not buy a bigger aftermarket MAF.

look at a vengeance racing for a head cam combo or check Texas Speed.

Your going to need big cubes. If you want "reliable" 500RWHP N/A AND plans to boost later on for more power...Not going to happen with anything below 400 CI.

I suggest stroked LS3-LY6 w/CNC ported Rect heads. Forge internals...would be highly reccomended.

Whta is your car?? lol

Anyway, there is a big gap to achieve 450rwhp OR 500rwhp.

For exemple, I have a LS2 SB with LS3 ported/milled heads/LS3 intake/ 1 7/8 headers/ORY/ a 230-236 629' 629'cam/rocker trunion upgrade/double roller timing chain/Morel link bar lifter with other boltons(MAF85mm/92mm TB/UDs/LID/Ram air), 3:42 gears, Monster level 3 and the wakky 10 bolts.

The car is pulling like a **** and I got plenty of torq from 2500-3000rpm even with the 3:42 on the streets and goes all the way to 6700. The car is good for 450rwhp IMO(anything less than that would be unrealistic cause my old 5.7l wasnt as fast and got 404rwhp on a stingy mustang dyno). It was street tuned.

So I took care of all my fear on a new setup(which was lifters, rockers and timing chain) and I feel confident its ''reliable'' for what it is.

BUT, I'd say the most reliable setup would be a crate LS7 Long block with the warranty. BUT you still have the stock valves issue to fix or be lucky(less than 1% have issue, like the rockers bearing fail, but I would be that 1%, I know).

I mean, buy a stock Z06 and enjoy LOL

I dont believe in FAST/RELIABLE/CHEAP <-----Pick only 2 of the 3.

if you want the right cam for a supercharger you'll be doin a cam swap if you build a N/A 500rwhp engine. why spend all that money on a h/c and build a N/A motor when you can build a LS1 for boost and boost it right away and not have to deal with surging if you have a good tuner

I second AI worked heads and matching cam, friend of mine has ported and milled 243s with a custom grind cam. Car is impressive for how much he has in it and is very reliable. Even driveability is still good.

Why not just Supercharge it now then? Easy 500 rwhp and later you can forge the motor and up the boost.

My car is a 2002 35thle SS with 5000miles on it. it's a m6
I never said anything about cheap. I would rather not do anything to bottom end though. I understand it would be best to swap cam for one or the other. I just didn't know with running low boost if it would be as dramatic. I do want to do the H/C swap first hell it may be good enough that I won't even want to charge it.

you should look at a fast 92mm intake with a matching TB.look at some trick flow 220 or 215 heads.or look at some air flow research heads,and get a cam from Tony Mamo.also look at the TSP PRC heads,the new 220 cast head or their 215 or 227 head.these are great heads and make great power with a custom cam.

TEA CNC TFS 215's, FAST 102/102 or 92/96, EWP, biggest lid/MAF you can afford or run SD with a 4" intake, and a custom cam from me.

Compression would need to be in the 11.5:1-11.8:1 range and tune will need to be spot on. If you can ditch some accessories also it would make it a lot easier. Every little bit counts.

daniel schopmeyer

Will the TFS 215 need to be milled to obtain that compression ratio?

Sales@Tick

That or the chambers need to be welded up to achieve this compression ratio.

I'd leave that up to the guys doing the heads or your machinist as they will differ between builders.
