As ValiantRich said I would get it out and on the dyno. Something is way off, the car cannot get out of its own way down low for sure. 60/330 numbers are anemic at best for that combo. Te dyno will at least let you know what it makes and what it wants for gearing and converter for starters.
As my good friend Al says, something is way off. I run a W9 450CID deal. I believe there are a lot of areas where you can better your combo.
