Not with Edelbrock RPM heads....

The only parts that play a role in how much power you make are the bore/stroke, heads, cam, intake, and compression ratio. The compression ratio on this one wouldn't make any difference unless it was a difference from 9:1 to 14:1....

I would guess that it's closer to 340-350 hp at the most. It takes a very nice head and cam package to get 1.3-1.4 hp/ci out of a 302.
