Part No.: AR361

Price: $225

Description:

Motor plate for LA style small block engines. Fits the 1967 to 1976 A-body chassis. Motor plate is made from 0.375 thick 6061-T6 material and is CNC machined for consistent fit and finish. The AR361 motor plate fits best when used with the WP115 water pump back plate from Meziere. If the back plate is not used then the fuel pump housing will need to be ground down or welded up.

An electric water pump can be mounted to the front of the AR361 motor plate. The AR361 motor plate is designed to work with the AR370 alternator kit. The AR361 plate is 33.25 inches wide and the engine is offset 1.375 inches towards the passenger side.

Part No.: AR140

Price: $50

Description:

AR140 is a 3/8 thick spacer for the crankshaft pulley on any Mopar V-8 engine.  This spacer is designed to move the crankshaft pulley outwards by 3/8 of an inch so the water pump will properly line up after installing a motor plate.  Pully spacer uses a universal 6 bolt mounting pattern to fit both early and later model engines.  Fits any big-block and Hemi engine.  AR140 is machined on both sides with ID and OD locating features to keep the crankshaft pulley concentric to the damper.

Price: $225

Description:

CNC machined motor plate for 1967 to 1976 A-body cars.  Plate is made from 0.375 thick 6061-T6 aluminum plate for extra strength and stiffness.  The plate measures 33.25 inches wide and the engine is offset 1.375 inches towards the passenger side of the car.
