I just got my v8 swapped '64 dart back on the road Thursday. I went from a 170ci slant and a 4spd overdrive, to a LA360 with a REAL 4spd. The motor I intentionally left very mild. It's all stock except for a 0.060" overbore, 9.3:1scr, a CompCams 268AH-10 cam with the required springs, unmodified LD340 intake, 340HP exhaust manifolds and a 750cfm carb.
The car is a riot! It very strong, considering how mild it is. It will incinerate the tires in 1st gear if I mat it. And it will idle all day long at a stoplight.
