[dbmx66]

i am asking this question for a buddy of mine who wants to runner a smaller shot of nitrous.

he has a 350 bored .30 over, with and eagle street/ strip rotating assembly, the crank is cast steel, keith black pistons, aluminum heads, 200cc with 2.02/ 1.60 valves with bronze guides, comp extreme energy .507/.510 cam flat tappet, roller rockers, edlbrock super victor, with a 670 holley carb.

it is a freshly rebuilt engine with 0 miles at the moment. he wants to know how much nitrous can this motor handle.

thanks david
