no tune as of yet...any guessitmate would be a great help. THANKS A MILLION

 

how does it idle?

 

368..

 

with no tune .. like crap!..lol

 

if this is accurate...im def going with a 200 shot of n2o

 

it's an estimate, I doubt it's over 400 if that's what you were shooting for

why the 241s?

 

wanted to keep compression a little lower for NOS.. or maybe a turbo set up in the future..bad choice?

 

What year lm7 is that?

 

01 lm7

 

That's 285 hp stock.

Bored 30 over -> around 3 HP at the crank but done mostly for C/R
Your cam is mild -> Let's say around 40 HP
241 Heads -> somewhere between 15 - 18 HP (Let's assume 18 HP)
Hooker long tubes -> around 18 HP
Injectors -> very minimal
Fast 102 combo -> 18 - 22 HP (Mostly in the top end)

So in total you should be around 389 HP. A 93 octane custom tune and you should be around 410 hp.
