Mcrews-i am really impressed that you were getting 28 in your old Mustang! I've only spoken to one other person who could get 28 mph. They did it by driving 55 -65 mph and tuned the engine on the lean side. He said that he had a little trouble with the lean mixture (heat) but overall it worked well for him.

Was your's tuned lean? Also when you rebuild the head, did you oversize the valves or increase the rocker arm ratio to decrease breathing restrictions?

Thanks in advance for your help!

Also - I am running smaller tires, 195/60R14. I like the smaller tires as they seem to improve acc/breaking/handling.
