The gears should be the same, except for hole in the center where the dizzy shaft goes through the gear. The engines rotate the same direction, so the teeth pattern are the same. You can swap cams with a 302 and 351W with no problems. When I was running my 351W, the cam was for a 289/302. I just had make sure I had the correct firing order.
