i wanna buy a new motor in the next couple months looking for a good shop/builder to do it.heres my two ideas point me in the right direction please.looking to have over 700rwhp thanks

first idea
built 383 with ported ls6 heads. built for procharger d1 15psi

second idea
big ci n/a motor on 91 octane

i really like the first idea but a big ci sounds really cool to me. im a lil new to the ls stuff my race car has a bbc so thats what i know alot about. this motor i wanna build is for a c5z not a dd but just a cruiser street car thanks

 

6.0 Iron block, 408 stroker motor, Ported l92, Fast LS3 style intake

 

im assuming thats a suggestion for a procharged setup?

 

Can you not use 93? I'd like to build a 11:1 408, with that set up myself. Or with a set of hefty ported 243's with larger valves.

 

no i can use 93 i was just assuming fi cuz u said iron block. what kind of power are we talking about with say 11.5:1 cr? what cam?

 

I say talk to the vendors. Texas racing are good people, awesome custom grind cams, good packages. A 93 tuned pump gas 6.7 stoker, the proper heads cam package should make a nice power band. Not sure how aggressive of a cam you want.

 

whats your budget?good heads afr 235,tf 235/245 or bigger,ls7 block with 4" stroke with a fast intake can make 650 hp on pump gas.talk to Bob at brutespeed about a supercharger.

 

my budgets around 10k. whos got a 650-700rwhp n/a setup? give me some specs on your guys builds thanks

 

I just read some build threads over in the other internal thread. I think I will stick with a procaharged setup n/a isn't gonna get me what I want power wise on 91. My boy has a stock headed 383 ls6 with a d1 @12psi making 620rwhp I think a 383 w/ported ls6 heads @15psi should get me around 700
