i am going to start building a forged 370 motor just to handle some boost and maybe a little n20. i plan on running the vortech t trim up to about 15-17 psi at the strip if i can make that and about 12-13 on the street . im needing to know what cr should i aim for if im planning on running 91 octane .I still need this to behave well for the street when not under boost. i dont mind running some higher octane for it when i go to the track. im also planning on using a stock 6.0 crank and cnc ported and polished 317's and a 216\222 .547"\.586" 114+3 cam. Id also like to use a little n20 on it like maybe 100 shot just at the track. Im on a budget for this and d like to do it as reliable as possible.im going to use the stock truck intake for now. When i do the n20 im going to use a new intake with direct port but thats later. is there any brand of pistons i should look for in specific? or any other comment or suggestions you may have to help me?

 

JE SRPs are nice, diamonds, wiseco they are all pretyt good get some that are designed for nitrous. No need for a DP setup if you are only going to run a 100 shot IMO.

 

im also using this set up with the cam in my sig, any ideaof CR i should aim for? im thinking like 9.5-1

 

Low to mud 9 would be good. Dont want to go too low or you will loose too much low end tq for when you are out of boost.

 

futral built my motor and he used diamond pistons and ceramic coated them! they are for boost with nitrous. iam 9. to1 i love my **** he is the man!!!!

 

Yeah, like me.

 

i like how the 10.1 runs now but i know its bit much for the amount of boost i want to run. but the main thing is i want a nicely street driven truck that can run fast at the track too.

is there any affordable forged stock stroke cranks? any of the previous c5 vettes have stock forged cranks?

 

TURBO8, what is your C.R.?

 

I know Eagle makes a stock stroke forged crank, its pretty cheap too.

 

You can stick with the 370ci and make good power and save about 1000bucks on a eagle crank. Or spend the extra $1000 and get a 408 with boost. The 370 will handle 800+ rwhp.
