Limit the front, tighten the rear shocks, move weight. on the Chassis side.
A dead hooked tire is a dead hooked tire its not a 4 link issue most of the time if you still feal it is get close or go under the 100 % anti squat line.
On the engine side. the TQ converter, go to a higher first gear and ramping timing .
If you move the ic out or longer it will keep the front down. We like to start around 55" out and 6 to 7" off the ground. You ic is too short, it will plant the tire but at frist but will tend to get loose out when you gain wheel speed.
Thanks for the input. I've added a 17lb weight on the nose and have the front shocks full tight. They are only the 3 setting type, but it helped alot from the first times out. I have never tried to move the instant center from where it is now. The car just always hooked good, so I was afraid to mess that up.
