Horsepower estimate?

Better heads will help wake it more, depending on the compression ratio and actual cam specs, but one thing I can guarantee is that 7.25 rear end ain't gonna last very long, upgrade that first before making any more engine upgrades, at least an 8.25 if not a Ford 8.8 or 8.75 Mopar. At this point I'd guesstimate it around 290 to 300 hp.
