Cm: Thanks.
Stock front suspension other than wilwood drag brakes
I would like to see lighter torsion bars and two way adjustable shocks as well.

ladder bars and coil overs in rear- no leaf springs.
8.75 braced, 4.30 gear/spool

Car went 9.80"s on the bottle with cal-tracs - no issues when stock stroked, stroked it and its torn up everything from tranny to driveshafts to rear end housing - made a horseshoe out of it.

Im trying to help him get car sorted as he had ladder bars, coil over installed.

we did an chassis dyno at end of season last year and then took engine to engine dyno- huge chassis loss showed up.
New converter based on dyno info , chassis was twisted- put it on a chassis table and had that straightened out, stiffened chassis.

went to test and tune and, car doesn't want to hook, i shot video of the pulls he got before throwing the shaft out - u-joint clamp failure.

rear of chassis has zero movement , front try's to come up but, tire unloads , cant hold separation /rotation.
My guess is you are correct- too much spring, shock cannot work.
rear of car didn't move up or down- locked out like rear is welded to chassis.
Tire bits, lets go, bites, lets go- porpoising the car.

we just had through tranny- it was fine, i then found the tail-shaft bushing was bad, had that changed , sent converter to be checked and should have it back this week and we can get 4 corner weights then.
