Replaced the Mickey N-50's with Hoosier 13.50-28X15's. Now I may have too much traction. Lays down at the start. What do you think about locking the distributor at 34* and relying on the MSD to retard the timing for starting? I have a stock convertor, stock 904 (manual vb), junkyard engine with a .480 284* cam, Holley 750 mechanical secondary carb. Need to launch below 2000 RPM.
