I'm in the process of building a LQ block for a 408 Stroker Combo in my 02 Camaro SS M6. Current mods on the car are:

Moser 12 bolt 4:10s
Tick Performance Built T56
Upgraded master Cylinder (Tick Performance)
Center force DFX clutch
All the bolt-ons
Forged LS1 bottom with 150 shot of spray.
Some suspension upgrades (tongue arm, control arm, sub-frame conn, and etc.)

On my Stroker Combo I plan to do a forged bottom with heads, cam, and intake with goals of 500RWHP, Give or take a couple horses. My ultimate goal is 700+ RWHP with the F1A installed, and If I make more than 700 no biggie. I'm not dead set on that number.... The more the better though!

My questions are:

What heads and cam would be a good match for this build, for good power with and without the pro charger? I would like to match the head and cam once and meet both goals ( I plan to drive it 3/6 months before installing pro charger, to fund it a little more. )

What other upgrades that aren't done should I be looking at during this build also? (Fuel, more suspension mods, and etc.)

The car will not be a DD and is mainly a street car with the occasional visit to the track and sunday freeway cruise. I have no concerns with gas mileage ( I see people use gas mileage and big horsepower in the same sentence a lot on here in these cars.....weird)

I want most of the comforts of a normal car, mainly heat/Ac, with some decent drivability ( with driveability spoken in the most modest tone). I'm more concerned with it having power than driving comfortably.

Any help or opinions are appreciated it.

So you basically want a setup that will make 500 rwhp n/a but also 700 rwhp with boost on the same setup correct?

6SPDN

Correct..

Everything depends on budget really. Are you building or having a builder do the motor work? Building a motor for boost is tough to make solid NA numbers that being said a 408 should get you close enough depending on the heads and compression you end up with. LS3 heads are what I use and seem to flow pretty well and for the price I could afford. As far as cams go I would call up comp cams and have them spec you one specific for your goals.

A 500 rwhp 408 build would be a pretty simple combo and shouldn't cost tons of money being able to use shelf parts. My mild 408 with 9.3:1 compression, blower friendly cam dyno'd 597 hp on an engine dyno.

If you end up with similar power numbers......that procharger is gonna blow your 700 rwhp desire out of the water. Time for a big fuel system.

Take a look at the dyno sheet found in the above link. This is from a Cadillac CTS-V where we started with a new LS2 block, used a Callies 4.0" stroker crank, Compstar rods, Diamond pistons, this cam, AFR 225 heads with a 9.5/1 compression ratio. Kooks 1-7/8 headers and a FAST 92mm intake manifold. We used a ProCharger F-1A and at 12.4 psi it made 864 rwhp on a Mustang Chassis Dyno. The customer took it to another shop's dyno day and it made 900 on their DynoJet.

It was at 809 rwhp in the links below. We started out with a GM LS2 intake on it and 14.4 psi of boost. When we swapped to the FAST 92 we lost 2 psi of boost due to the intake being so much more efficient. Power though went from 809 to 864 rwhp.

For the fuel system I recommend going with a Lonnie's double pump system and go with the optional teflon lines. Bob

are those numbers from a factory casting or Aftermarket head?

i would say build something around 10:5 scr, ported 243's/ 799's ls6 intake or ported ls3's with ls3 intake and have a supercharger cam spec'd out and have it in there right off the bat. may not quite make 500 but 475 should be pretty easy . use some ls9 gaskets and head studs. twin pumps on a hobbs. the twin 450 setup a dude sells on here seems to be a decent deal. run u some braided lines,aftermarket rails, 100 + lb injectors and u are set. even be good for e85 if your injectors are big enough. the cheap bosch 160's with a driver box have been used in a crapload of engines. or splurge for fic or morans. just my $.02

Understood. I got some L92 heads I can get for about $500 that haven't been touched. I just want a durable setup that performs well on a decent budget. I was looking at the 225cc TF and AFRs and I like the head options, but I'd like to save myself the 1k to spend else where in the build if possible. You all don't think I'll regret the L92s in the long run?

Having the RIGHT cam in the motor is what's key to those L92 heads.... they either make or break the whole combo.

6SPDN

looking at doing the blower cam from bob @brutespeed

Tuskyz28

I can't speak good or bad about Bob. I would ask/look for PROVEN results out ANY cam you choose espically using those heads. The big intake valve makes them very sensitive to overlap....

That is an impressive gain going from an LS2 intake to a FAST 92. Was the LS2 intake stock and was the intake swap the only change made. Most people on these and other boards downplay the need to go to a FAST when going forced induction and say it is a waste of money. The results you posted definitely have me rethinking that. Thanks.

I am running a factory cast ls3 on 9:1 comp 408. My heads have a competition valve job, titanium valves, and comp springs with titanium retainers.

6SPDN

no issues? What can are you running? And I'm assuming it's a boost motor with the 9:1 comp.?

KyleLanter

No issues to speak of have around 2k miles on it. Comp cam 227lr. Had comp spec me one after telling them my plans and yes it's a boost motor

i appreciate the replies, what's your setup, and Rwhp/tq numbers?

[QUOTE=6SPDN;19388397]Set up NA numbers were 440hp/440tq. That was threw a slipping clutch t56 and 10 bolt with 4.10s. Tuner left everything pretty conservative since the motor had 500 miles and he knew I was just tuning to break the car in before boosting this winter.
