Building a new 505 With Callies / Mopar Performance Block

New 727 with a trans brake put this car for a loop. It was really hooking last year but not this year. Found that the rear end housing tubes were moving in the dana housing and that the leaf springs gave up the ghost. Slowly but surely we are getting the car where it needs to be. So far we have picked up about 3 and 1/2 tenths this year. Started out running 7.08 now it is running 6.73.
