90a Denso
Stock brackets
Stock heads

Only modification was to trim the stud on the back.

Just how it worked out for me on a Small Block. I would still like to get my hands on a smaller pulley for this alternator..or a larger crank pulley. We'll see, may be serpentine on a magnum block soon enough. But the charging at idle with 90w H4 lights on, stereo, electric fuel pump, and my fan pullin 25-30a...it's not quite enough at idle.
