If you want to be realistic--- 301 cu in and 188HP from a 700 pound + engine sucks. You could do better, and cheaper, with a 318, 302 or 305. But if you want a cool engine for an old style hot rod, you have one. As often happens with obscure fifties engines, with little or no speed equipment available, I wonder if a Paxton supercharger would be the answer to more HP ? You could use any kind of supercharger you want, and the engine will stand the gaffe. They used the same block, crankshaft and rods in blown fuel dragsters in the fifties.
