Currantly running my GM alt. with Butlers relocation bracket on drivers side of car. Both wire input and Batt. mounts are behind the Alt. lying right up against my aluminum heads. My question, does anybody in the forums know of a GM Alt. i can mount with both terminials relocated to the top side of the alt. and Not the backside??? Running a 65 AMP style factory alt. I can post a picture if needed to show what i mean.
You can clock the alternator. Should have 3-4 bolts with a star head. Remove them, spin the back, be carefull not to pull to far otherwise the brushes could fall out.
If it was me, I would go with a little more amp 1 wire alternator.
