application: 91 Z28 350 TPI auto (T56 going in within the next month or so)

i am most likely buying a base 383 stroker motor to start everything off with or if i can find an already bored .030 350 block w/ 4 bolt mains ill go from there.

plan: to run 20 PSI from Procharger kit

from here i will need anyones help as to what will be the best parts and if they will all work in order together:

1. TrickFlow Kenny Duttweiler sig heads w/ 72 cc chambers 195cc intake?
or
2. Dart Pro1 230 cc intake 72 cc chambers?
3. ESP H-beam rods
4. ESP forged crank 6.0 rod journal
5. JE HD Pistons inverted dome
6. Comp Cams Nitrous Cam (good for forced induction engines)

thats about it for the main components

now, for the best match to support forced induction and provide most power, which should i choose?

Stealth Ram
Mini Ram II
Super Ram

if its a close call between any of these, i would like to retain my strut tower brace and i know the HSR is too tall for those so...is the Mini ram lower?the super ram? but if i am going to get a big power difference w/ the HSR i will get rid or the brace.

project begins spring '04 so until then and maybe during, i will be trying to get as much info as i can on building up this 383.

 

Well, I think that if you are running 20psi boost, I doubt that the intake is going to make a difference. So go with the SuperRam with some porting and you can still use a strut tower brace.

Qualifier: I have no experience running a SC.

BTW: I would recommend a splayed 4 bolt block for sure with 20psi boost.

Also, choose an appropriate fuel injector for 20psi boost.

 

Thats a lot of boost dude. What are the specs on the cam. What is you goal compression ratio?

 

does anyone know if this block will work with all my L98 OEM accessories ( oil pump, water pump, etc..)?this is a Motown race block and if i decide to get it i am bringing it to a prof engine builder to bore & stroke it get it all ready for assembly.

WOW, sounds like you may need wings!! with that much boost you may want to use the miniram, it is alot easier to work around, alot easier to install, and sit's plenty low for a strut tower brace.
