Well, the 302 and 289 have the same bore at 4.00 inches. the difference is in the stroke, 289:2.87, 302:3.00 . the blocks are almost the same, the 302 has slightly longer bores to help stabilize the piston on the bottom of the stroke. Because the 302's longer stroke, it makes more low end torque, but they both make the most power at hight rpm. I put a 302 crank in 289 block andd called it a 289. Impossible to tell from the outside. More cubes=more power.
