New Engine

Money aside, I've been researching a monster project. I though for a long long time about turbos, but have been thinking lately that I wouldn't need/use them for anything. Here is my design:

 

Dart Iron Eagle Small Block Chevy

Eagle 4340 Forged 427 cubic inch 11:1 bottom end

AFR 227cc race heads, 4 angle valve job, top quality work

Cam on the order of 250 degrees, .600+ lift

TEC3 engine control

Holley Stealth Ram

 

With the engine control's 4 stage nitrous control, I'm thinking a 400-500 shot for the track would be exactly what the Dr. ordered.

 

Any suggestions with this?

Man, I can't make up my mind. It's really a decision between what is listed, and the same engine only 8:1 compression and 16psi boost on an F-2 procharger. That F-2 would remove any impression of sleeper-ism I planned to keep....Not like it matters when you have 750+++ hp on tap. I dunno. I'm supposed to figure this all out and then make a final proposal to sponsor.

The law of diminishing returns seems to apply to small block Chevy's when it comes to displacement. I think you can make as much power building a 406 and not have as many problems with rod/crank/cam clearance. Crank and pistons should be cheaper as well. The slightly shorter stroke should be more tolerant at 11:1 also. My buddy just built a 427 small block for his S10. 550 hp with Victor Jr heads, but it has TOO much cam and TOO much compression IMO as I like to maintain streetability. Chevy high performance built the GM 383 HT and got nearly 500 hp and over 500 lb ft for about $6000. I think you are right to stay 250 or less a .050 on the cam. The trend with turbo V8 is smaller displacement rather than larger. A 327 or 350 is the way to go for forced induction IMO, and all that money you saved on the big stroke/bore parts can be spent on turbos and manifolds. If the motor isn't the killer on your wallet, the mods to the car for those power levels will be! I'm just not a nitrous fan although I have run it on a couple of different cars. It just gets to be a hassle not having the bottle on when you want it, not having a full bottle when you need it, driving all over trying to get it filled, having to re-hydro test the bottle every couple of years, wiring, plumbing, bottle heaters, purge valves, etc. Long term, turbos are probably cheaper, and definitely quieter. Being fast and quiet is cool.
