Yes, not enough stall, gear, or timing for that cam.

Compression is a bit high but the alum heads should make it OK. I ran a similar sized hydro cam, dart iron heads, 11:1 and it worked great for me.

Either drop compression and cam duration OR add stall and gear. The engine will need more timing no matter what you do, so try that first.

I would try 38 total mechanical timing and see what happens (listen for detonation). Are you sure the timing marks on the balancer are correct?

What carb do you have?

Do a compression test and check for a flat cam lobe.

You have a big heavy car there. Don't expect too much.
