Ar some point you’ll probably end up with a different carb & intake manifold either way, I think.
It’s so easy to change intakes on a Pontiac, I’d try that first. It might make enough power for you without going any further. Do the compression test as mentioned above either way. It’s always good to know what you’re working with. I’d also plot out the ignition curve to see if anything weird is going on. I’d also check to make sure the timing marks on your damper are tell you the truth.
I agree with everyone else, the cam is too small but it should run better than it sounds like it does now.
Good luck & try to have fun getting to know what you’ve got before going in deep. ��
