I am building up a new 305 engine for my 86 camaro with tpi now it runs the best of a 15 flat the new engine is going to have 350 lb9 heads, federal mogul forged pistons, comp. camshaft 211 intake and 221 exhaust, 10:1 compression, and i will add on a bigger throttle body prob. a 52 mm. what can i expect to get out of the 1/4 i also have a 150 shot of nitrous but what will i prob. run without the nitrous i think the rear gears are 3.08
thanks

 

350LB9 heads huh......no such thing. you must mean L98s or vette heads. thats a pretty big cam for a 305 with 3.08 gears. probably mid 12's on the nitrous and around a low 14 on the motor, its hard to say

I really don't know why everyone wants to make a small bore 305 engine into a race engine. It's easier to build up a 350 than a 305.
