67 Cuda: disappointing dyno numbers, need some advice!

awesome thanks for the responses guys, I'll get a compression gauge and see what it looks like. Based on that hughes cam is there any intake manifolds that would work well with it?

Edelbrock Air Gap seems to be about the best for hot street setups. There are some good vintage choices such as the Holley Street Dominator you might could find at a decent price if you're on a budget. Yes, that's a single plane intake, but it loses nothing on the bottom end because of its design. It's a well known and very good vintage intake. I would find one of those before I plunked down 350 clams for the Edelbrock........but the Edelbrock IS a good piece.
