My 422 smallblock build

Hey before you go to far check your oil pump drive into the bronze bushing to make sure it fits good. And put a 1/4 inch rod down through the top oil pressure hole to double check to make sure the 9/16 plug was installed under the rear main cap. Easy to fix now, hard job later. Measurement from top of block to plug should be 7 1/2-7 9/16 inches.
