275 from the factory. I would say with those mods, add about 10 or 15 more motor hp. I'm sure someone else will chime in differently though.

My previous motor - 1.6 roller rockers, stock bottom, stock cam, BBK shorties, gutted cat, Hooker Cat back, and Moroso CAI, and a dyno tune - 286 rwhp / 320 fttq

I don't think the shorties and Y-pipe did much (8-10hp maybe), the 1.6 rockers (8-10hp) which would explain the gap. I'd say 265/270 hp, but only with a good tune.
