The lower pulley is the basic B&M unit, which I believe is intended for the SB Chevy application. There is a spacer behind the pulley which required some slight modification on the backside (the side that goes against the Mopar V-groove crank pulley) in order to get it contoured the same as the larger Mopar pulley and fit securely.

The mechanical fuel pump would have been used for the dyno testing; however, with the planned conversion to Powerjection throttle body fuel injection I will be converting to an electric fuel pump.
