can my engine take it? 89 vette engine, zz4 cam,1.5 roller rockers,headers,eldebrock intake, aluminum D port heads, 650cc holly carb, engine was take all apart before i put it in, everything looked good i cleaned everything all up compression was between 155-170 on all cylinders.

Yes it should be ok, Just make sure your fuel delivery is strong and should be no problem. Question how did those heads work for you on the stock bottom end?

they have worked great so far no problems at all just finding D port headers was kinda confusing at first lol but i worked it all out. i got my car stolen and they redlined the **** out of it and blew the tranny that is hard to blow so i know the engine is strong becuse it came back puring so the heads have worked great and there like 40 lbs(a piece) lighter than the iron ones, and by the way they are off of the 89 vette so there nothing super special but definetly better than the stock ones.

I say after about 15 or 20 runs with nos your going to need new pistons. just put forged pistons in now and get it over with. You will be glad you did.

I'de say you'll get more like 500 passes out of the car on spray before you need anything special as long as you keep it rich and make sure you never run lean. Nitrous isn't going to hurt your car more than any other power adder if done right. Actually it can HELP your car last longer over other power adders due to the ammount of torque produced allowing you to keep the revs lower.

I totally agree with 1991camaroRslow keep it fat on the bottle and don't activate it under say 2500 rpm.
