Hello from Oil Country

welcome fellow 68 fastback owner! you're in the right spot. the buildup sounds good. i would rethink the ss springs and maybe go with xhd. unless you got 2 left or 2 right ss springs since they lean the car to one side if you go with a left/right. yep, 440source is the place. i just sent a 440 to the machine shop that is getting the 500" stroker kit. i am about to fire up the 438" that was stroked from a 383.
