is my cam to big? I have a custom grind nitrous cam that is a 236/250 .612/.612 114+4 lsa.. I am looking for a set off heads to go with this cam but I haven't found a set just yet. I also plan on installing my ported fast 92/92 with 36 lb injectors...I also might be adding forged pistons and rods too my ls1 but for time being ill say stock bottom end..

Need more info....weight of car, gearing, trans (M6 or A4,3), clutch or con-
verter, intended compression ratio, use of car...some street, all drag, etc.
Also you'll probably need to flycut your factory pistons for that stick to clear
or use heads with 2.0" intake valves

Yeah I'm going too have too fly cut its a street car but that's a loose term in my book right now it weights 3400 lbs with me in it I'm trying too get it down too 3200-3100 with me in it.. I'm shooting for a 11:1-11:5:1 cp ratio so might end up putting rods and pistons in it
It's got a 4.56 gear with a 28" tall drag radial sO I should in theory run around a 129 ish at the top off fourth shifting at 7k which is the reason I picked this cam but I'm wondering if it's too big oh and it's a m6 car with a spec state 3+ about to go in it

Some Advanced Inductions HC241s or 5.3 cnc'd heads with a .045" Cometic
head gasket should get you to mid elevens compression which would work
well with that cam but the 4.56 gear is more correct for NA where as a 4.10
would probably work better for the NOS. Since the engine makes so much
more torque on the **** it revs way faster and you don't want to be runnin'
her 7200-7400 out the big end. I know many on here do this but I feel it
would hamper reliability....street car and all.
