Well I had it moved from the question and answer section hoping that some of these restoration guys had ways to up the performance on their motors without having to swap out too many factory pieces. That was the goal was to simply up the perf. without having to do major mods to the existing factory motor. But I'm finding out that that's not possible. Plus I don't see a performance section anywhere on Moparts anyway.
