Default whats you opinion?

i have a 95 Z and its a 355 with .30 nothin special pistons, comp cam like 210-220 dur and 510-520 lift, ported and polished heads by a local, polished intake, stock rockers, stock tb, lt headers, cai, and so far on the dyno i made 270rwhp with stock fuel system and a miss. i got the miss out of the way but havnt got to the fuel issue because it keeps leaning out. but my main question is what rwhp range should i be at, i think at least 300rwhp. this is an auto. what you guys think?

Your combo running properly should put down at least 330whp.

Unless mechanically wrong stock injectors will support upper 300's w/out going 100% duty cycle.
