Another thing, on the DUI HEI's, be ready to spend over $300. I would just get a better coil and module like from MSD to put on your HEI. No need for a whole new distributor, just freshening.
I would keep the 4.10's. You have decent RPM's crossing at the big end of the track, going to 3.73's will only hurt that.
I totally agree with Travis.
Change the heads to a good 64cc head, and mess with the timing and carb, and you could be seeing low 14's if not high 13's soon.
Keep us informed!
