Wanting to bo racing again after I get T-Bird re done and some engine improvements. Ran 6" recap cheater slicks from '67 Actualy had great traction. Running .30 over 312 with Crane cam and factory dual quads. 3 speed with 3.89 rear end. Was launching at 4500 to 5000 and was hard to catch off the line. Best ET was high 14's. Ran 4.11 and 4.57 and still had adequate traction. Going to Mummert heads and a little more radical cam and 4 speed. Will run 4.11 or 4.57 rear end. Looking for tire suggestions?
