Chassis Tuning

If your converter stalls too low. Leave at idle. Give the motor as much of a running start at the converter as you can.

agreed, was gonna say the same thing. Might hit that dinky convertor harder.
Stock stroke small block Mopars like convertor, all of them.
I would be looking at a tight 8 inch somewhere around 4500 flash.
Car needs to be running more than 5500 at the stripe too….if you are looking to make it ET better
I would also crank the T bars UP…. Help get the car on the tire and transfer weight easier, especially without a convertor.
I ran a heavy(3350 pound) 9 sec smallblock for years on 002/003 leafs, they work.
Video would help
