I have a 73 block 455. I've rebuilt the motor with a cam (113LC, 286In, 302 out) and yanked out the old pistons, for the 10:1. Topped her off with an Edelbrock 750. I have a 68 Electra 430 sitting in the garage, I hear that the 430 heads will do better on the stump puller. Any suggs ???? Red Smith Dallas, Texas 1967 Lesabre Conv.
