Default horsepower

the cam is a little small for 12-1 compression without adding the nitrous i would guess 415-425 add bigger cam and match the cams rpm range with the heads and intake none of your parts look like they match each others rpm ranges so hell you might only get 375hp

I suggest lowering the compression if you wanted to stick with that cam. Are you looking for a race car? That is track kind of compression, too much for the street unless you dont mind race fuel or running the timing way back, then it will not run optimal.
