Class: heads up 8.0 index on a .400 pro tree
must be footbrake

my car 3750 lbs
4300 stall
4.30 gear
26X10 et drag
moroso trick springs
summit adjustable shocks 90/10 front 50/50 rear
caltracs set pretty stiff
454 BBC
350 turbo trans

Right now I stall on the brake at 3000 rpm and leave on the first yellow. My lights are .480-.490.. The winner of the class is usually .450-.460.. So I need a little more. I am thinking of this:

M/T ET drags 28X10 S -- stiff sidewalls
Loosen up my caltracs a little

ANy other ideas? I have subframe connectors and a 6 point cage.

Cannot loose anymore weight and keep it a street car. Thought about restalling converter to 4500.. I have to shift the motor at 5000 to keep from running to fast..
