Have to agree with the heavy wire thing- my Galaxie has 4/0 aluminum wire from the trunk battery to the solenoid, and also battery to the frame, and welding cable from solenoid to starter, since 1978, starting with the 14:1 427 engine. Had the same starter all that time, a used factory 302-2V unit that I swapped the nose to the 3-bolt FE nose, still spins it fine with the current 12:1 deal
