ya i built it just didnt think it would be that much horsepower with the nitrious ill just skip out on the nitrious maybe this summer get a new block build it up a little so what you are saying is just jump down to a 10 pound pulley and no nitrious and that shouldbe good for driving

So you have a 347, a V1 supercharger, 150 shot of N2O, better than stock cam, and you are running stock heads? You skipped over one of the most important parts of your motor build. Therefore I feel the hp #s they guys here guesstamated are to high.

+1 on the stock heads yeah that thing isnt going to be anywhere near what i guesstimated,,, haha,, sounds like he upgraded from a 302 v1 s/c and 150shot to a drop in 347 kit, but didnt get much better cam or heads, prolly had the cam already done b4 the 347 swap, he needs heads and cam bad and prolly exhaust

I'd be surprised to see 400rwhp on that setup w/ E7's. If you switched to an aftermarket head you'd probably be at 500+rwhp w/o the spray. I wouldn't spray that motor.......period. Get a new block before you go that route.

thanks for your guys help anyone getting rid of a nice set of heads or what heads you guys think i should go with is that cam alright
