Tire question

wedgie said

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.

You definitly need more stall with that cam, thats the main problem, the other is running a DPer with a stock converter, so you have 2 strikes against you. With those other tires you had (spinning) it got you in the RPM range "early", but spinning won't get you anywhere. If i were you at this point, get a good quality 9.5" converter that stalls up there but is still street freindly, dial-in the tune (timing curve) & you should be set. I'm running a PTC 2800 11" behind a mild 360 magnum with a small roller, I wished now i would have gotten a 9.5" that flashed around 36-3800, my 60fts are in the 1.85 range, thats not bad, but i could have easily been in the 1.75 range with a 9.5" for an extra 100.00 bucks, stupid me :angry7:.
