confused - or just a stupid question

The heads are the original 318 heads. They had a 3 angle valve job and ported for better flow. The car takes off pretty good from a stop and sounds great. But won't do a damn thing as far as burning out. I know it needs a better gear, but that is something a little down the road. Maybe late this summer, if I happen to see a good deal at the Mopar Nats.
