Ron made a good suggestion with Desktop Dyno. It was off 4hp with my engine. However, the torque was off like he said...and I can't figure out why either. Oh well.

I'd say you're in the 230-240 hp range at the flywheel. Does the car have a straight axle or IRS? That would change your RWHP.

As for more horsey-power, I'd start with a head and cam change. You can get some pretty big numbers out of a small block without being really radical. Ford Racing offers a 340hp 302, so you know that's do-able with GT40-X heads and a mild cam.
