383 Engine questions
The thing is he doesn't want a stroker kit as he stated in the original post.
I would op for the 452 heads myself and do as they have suggested already. I have used a 280H cam and it worked very well with a 2200 converter and is almost a stock replacement for the HP 383 Road Runners.
I like your idea of the little sleeper, OK well BIG sleeper.(C body)
