motor plate.

Don’t machine it off the face of the WP, take it off from the pulley side.

Make sure you use a WP with a plate on the impeller as the engine plate will make the pump much less efficient.

i'll be machining the timing cover not the water pump. the motor plate is open where the water pump impeller goes, it's cut to match the inside edge of the water pump gasket.i'll end up with the impeller being in the same place as it was in relation to the timing cover so as far as the pump's function that won't change. if my pump isn't a 'disc' backed type i'll probably cut a stainless disc and rivet it to the impeller blades to improve the efficiency, good idea. :thumbsup:
