I agree with the adjustable shocks would be nice to have some expierenced help when you are testing.I am not sure this will help,I have used it got it from Herb Adams take front leaf spring mount(this is on rear now)take off car drill hole min 5/8" higher than existing hole. Then you must cut out top portion of bracket for spring to fit back in. This is supposed to increase your anti squat.Basically keeps car from squatting down because springs are pushing up. Wish there were some shock eng's out there that could help us all because I believe we make the power but need to getit to pavement.Just ballpark adj's would be enough. I tried Koni but I'm a nobody. I did this to 73 F-body with SD455 stock lift cam(407)3300 stall con,4.10's,slapper bars 9"slicks,1.50/1.52 60'.Good luck don't quit let us know. 'you just can't leave anything alone can you? Unh-a'
