I am planning to run a local Mopar race that is for street cars and does not allow slicks for the bracket race. I have tried radials years ago with not much luck hooking consistently, it would hook one pass and then blow the tires off the next. I normally race with a 29.5 x 10.5 MT bias slick, but wanting to run on my street tires 295/65/15 ET Street S/S. With slick and old motor the car has been 1.43 60' time. Current motor is a 5.7 with supercharger and is lazy in the 60' (1.5649 best 60', 6.6206 1/8 mile at 106.11 mph, 10.3120 1/4" mile at 132.70 mph)

The car is a 73 Challenger about 3650 lbs
Calvert mono leaf springs and bars, Strange double adjustable rear, and Calvert 90/10 front
4600 converter with 4.10 gear

I am looking for a good starting point on tire pressure and rear shock settings. Any help is greatly appreciated.
