Suddenly I feel old, My first car was a 67 Rambler American I pulled the 6cyl / auto (actually my dad did, I just handed wrenches) we swapped in a 390 with a 4speed, Dual exhaust, chrome reverse wheels. I got so many tickets with that car was soo cool (that was 74) I remeber we changed several rearends they kept breaking... good luck with the R/A
