What heads are on it now?
Have they been gone through?

Is it spinning now?
What are the 60’ times like?
100mph is good for a very low 13.

How sure are you about the “10:1”?

If the heads are fresh........ I’d suggest having a little porting done, swap to a solid lifter cam, more stall.
At that point you’ll need some sticky tires if you don’t already have them.
