I can't get over how well mannered your car is to be ripping 10's. Equally impressed by the 1st gen you ran with, he was hauling ass, wonder what he ran?

The time slip in post #412 appears it may be for the 1st Gen. He left early. If that's correct 9.723 @ 136.07.
I like to think the suspension was on me. But I handled it the same as I did Baxter's 1.2x 60-ft, low 8-second 30th SS. I told him to take it to Steve Spohn. Steve supplied a lot of the parts. I had one of his very first adjustable torque arms. When I had my car at his shop installing his LCA relo brackets, he looked at the torque arm and figured he had to reinforced it. When he saw what I was doing with the engine he upgraded to a newer version. When I had the Gear Vendors installed, he built me a custom reinforced torque arm, to clear the GV, and with the driveshaft loop moved back onto the arm so is was correctly positioned within 6” of the u-joint. He installed it and set up the pinion angle.
Also comped me newer adjustable LCA's with spherical rod ends. When he designed his first “race version” adjustable rear sway bar (1-5/16” solid chrome-moly) Steve and his dad used my car for his first install, so he could check for glitches and write up install instructions. He set it up with me in the driver seat. The quality of his parts (certified AWS welder), his knowledge of the workings of the torque arm suspension (he raced a 3rd Gen and took courses on suspension design), and his ethical business practices made for a good guy to know. I met him online - he was looking to borrow a T56 so he could design a complete kit to install it in 3rd Gens. I had a spare, drove out to the middle of PA and dropped it off. He returned the favor many times over.
I'm still trying to figure out how the bolts for the steering wheel adapter plate came loose……

Yes correct.
Suspension is set up pretty well, but since you set it up for a bias ply slick, and im running a radial, i have some adjusting to do.
Car has amazing separation instead of rocking backward like most fbodys, but with a radial, it hits the tire too hard and the radial being stiff it springs back about 5-10ft out and then starts hazing the tire. thats killing my 60ft.
next track outing i will be playing with shock settings to try to slow down the rear separation and also slow the front down from lifting so quick. hoping that brings the 60ft down
Also, i am in progress of planning a 2nd stage/2nd nozzle. 200 on the hit is a bit aggressive, and the only thing i need to do it is a 2nd nozzle and fuel solenoid, i have everything else.
Plan is to rewire the system so 1st stage is just wot switch, jet that for 100-125, then second stage interlocked with wot switch/wired into window switch for say 4200-7000rpm jetted for an additiona 75-125hp.

I haven't had my car back on the track with the Mickey's. At the track on street tires it was just like like my signature, "no traction till the top of third gear".
When I hole shot it on the street on the drag radials, it plants the tires at first then seems to unload the tires and possibly the rear of the car lifts and smokes the tires bad. This is right when I have to shift second gear and then I just boil the tires all the way through second.
Does the front of my torque arm need to go up or down to improve the tire plant?
I'm having a hard time wrapping my head around the suspension science.
