You are lacking knowledge of launch ratios. If you multiply the rear gear ratio times the first gear ratio, that gives you your launch ratio. Ideally, around 10:1 works best. In other words, your 3.73:1 rear ratio times a first gear ratio of around 2.7:1 would equal 10.07:1. Your PG trans will have a first gear ratio of 1.76:1 if it's a stock first gear, so one or the other needs to be changed in order to afford you optimal launch acceleration. Either use a different transmission that has a first gear ratio around 2.7:1 or change the rear end ratio to something in the 5.57:1 range (12-bolt) for a 9.80:1 first gear final drive ratio. Your current final drive first gear ratio with the PG and 3.73:1 rear gear will be 6.56:1 and you will be very disappointed.
As far as a lumpy cam, install a CompCams Mutha Thumpr. It'll work with your 9.5:1 static compression ratio.
