Should I go for it??? (408 build) Here is what I am looking at doing for my Procharged D1SC GTO Setup
Bottom End:
Iron 408 with 9.0-9.2:1 compression
Core 6.0 LS1 Block
Eagle 4340 LS1 4.000 Crankshaft
Scat 4340 LS1 H-Beam 6.125 (.015 offset)
Wiseco Custom Pistons
Wiseco Custom Pins 9310 .170 wall
Wiseco GF Piston Rings
Federal Mogul 152M 3/4 Groove Main Bearings for LS1 (coated)
Clevite CB 663 H Rod Bearings for 2.100 SBC Chamfered Race
Bearings (coated)
Federal Mogul 1888M Cam Bearings for LS1
ARP 234-5608 Main Studs for LS1
Heads:
ETP CNC Ported 240 Heads
New Castings with 11* Valve Angle
Fully CNC Ports and 58 CC Chamber
2.100” Stainless Intake Valves
1.570” Stainless Exhaust Valves
FTI Dual Valve Spring Package
Viton Valve Seals
Includes Custom Rocker Stands
338/231 CFM at .600” – 4.000 Bore
Custom Grind Cam
Upgrade to a custom FMIC system to support the power.
Go to 75# injectors high impedance
Boost regulated FPR
Eventually build the tranny...
Nitrous Outlet Plate system (50-100shot) Probably won't go on for a while though
Anyone have any guestimates of what I should be able to put down with this setup in the M6 GTO?
So should I go for the big build up!? I know its my choice and I am pretty set on it, but does anyone think I should do anything differently in the build?

Looks like you have it pretty well thought out, I'd go for it. You are procharged right now correct? What pulley combo do you currently run and how much boost are you seeing? Don't know if a D1 will cut it with a 408, might have to go with the F1 if you can.

RevXtreme will be doing the tune/work on the car and they have a few D1SC powered cars making over 725 at the rear wheels with 408s.

I'd go with the F1 for the 408, and yes, I would do it, if you can afford to. You'll be at 800+ hp with the heads you're looking at, along with a good camshaft and somewhere around 16 psi of boost. The GTO's rear-end is never going to forgive you!!! Bob

you will have to go with a spool in the rear now definitely. might want to look into beefy driveshaft and building up your trans along with like a spec 4 clutch now rather than later.
its only money. if you want to be top dawg among the gto's go with a turbo.

No turbo for me... As much as I would like this car to be an all out drag car it will never be just that. It will always be a street car with tons of power to pretty much terrorize anything on the streets. When I want to build a big time race car I will build a Camaro/TA!

since the gto is heavy as a pig already and the power level you are going for is not astronomical i'd go with an ALUMINUM 402. Even though the power level is going up you are adding 100+ pounds to your front end.. Plus since the engine bay is already pretty heat soaked that iron block is just gonna make it worse. just my opinion. lighter=more power to weight ratio.

textralia for the win , might as well do the clutch and have the tranny built while its out of the car than have to drop it later. I'd go with a denny's nitrous driveshaft, forget aluminum.
maybe do a ford 9 inch too!
