Randy, mine has Caltracs & monos with 295/65 M/T DR's and it hooks good with 720ftlbs of tq

Chip runs the same suspension & tires on his Cuda and 60fts in the 1.30's with his 572 Hemi

Brad H also runs CalTracs and 295/65 M/T's and 60 fts in the 1.40's


My vote is to not cut the car up, use a bolt on traction improver and use a 295 DR



Ron


Ps. On a side note ; i'm wondering if those a-body SS springs might be causing some type of problem ? Are the rear shakles facing forward with the chassis loaded ?
