Had a 468 built for a boat that worked real well with just port matching work on a twin 660 carbed tunnel ram and iron 990 heads - was doing about 600 hp on pump gas flat tops, chevy forged rotating assembly.
Upgraded it to a stroker 496 now with the same top end, ported iron 990 heads with bigger carbs (twin 850DP), Crower complete rotating assembly and about 10.5:1 - 17cc dome pistons ans still running 91 octane and getting a bit over 700hp. all engine work came to about $3400 just 3 years ago. Prices are changing but I still think you'd be miles ahead with the BBC.
I have a set of 088 Rectangular port heads (off a 502) that will work for a Gen IV BBC. These are good iron heads, 118cc chambers and 2.18 / 1.88 stainless valves already double springed for a hydraulic roller cam. I have the mild cam and roller lifters too if you need them.
Building a 509 for my truck right now as we speak for some 700+ street/strip horsepower.

Are these numbers from actual dyno runs or just guessing?
