Yeah, 289's with the two barrel put down 130hp @ the wheels in good original tune. They can be made into much stronger runners, but that's not what we went for. The body integrity isn't there for a whole lot of speed.
A cam alone would have made a big difference because stock cams are especially conservative, and there are some head options which would have backed up a slightly beefier cam, but we consciously chose to pass on those options when building the motor. The car's a cruiser, after all.
