SBP to LBP conversion

Lol, no if I upgrade the engine it will be a swap to a 360 or 408 to easily get the HP and torque. The bigger brakes (possibly Dr Diff Stage 3 set-up) would be for handling and braking. I am thinking P225/45R17 front and P245/40R17 rear. I think that I will give Dr Diff a call to discuss the set-up. I have seen quite a bit of stuff on this forum that he is a straight shooter.
The car is a column shift auto but a stick would be nice one my first cars was a 72 Challenger Rallye 340 with Pistol Grip. Feel bad that I trashed that car 40 years ago (was a lot of fun though).
