I'll tell you some thing If you do put that 302 in the other car. Go and get one of them old 351windsors it will bolt right up to your trany and motor mounts, 1969 was the best year. They had 290H.P with 4V carb stock and 10 to 1 compression,good engine.
And they used them in the Mach 1's hope this helped.
