451 Stroker Build
I love the sound of a big V8 over 6500. And in some scenarios RPM is good. My buddy races a Ford 460 and traps at 8400rpm. It sounds more like an electric motor than an engine at the stripe.
I have no idea what the 451 has for a top end, but IQs power curve has a lot to do with the head choice (big volume for the displacement) and potentially a much better cam. And the valve train wasn't eating itself.
