here are the 1/4 info you requested mr p-body r/t-.656 60'-2.123 330-5.88 1/8-8.99 mph-79.30 1000-11.6876 et-13.98 mph-98.07
can't find previous best slip, but i know it was 12.7 @105mph
I was foot braking it-launch @3000rpm, small wheel spin, and shifted at 6500rpm-trapped at 6800rpm(if I remember right). any useful thoughts????
Looks like most of the problem is the low end... like its lacking torque to get it rolling... I would degree the cam in FIRST and add a few degrees of advance for the heavy car... also seems like a lot of rpm for your gear
