I'm using that pump with the stock cover and a 1/2" internal pick-up. It's sweet, takes less power to drive at a given rpm than a stock pump and with the stock cover, and fits just like the stock HV pump body.

The lobes on the gearator are much more pointed than the factory lobes. Be sure to port match the pump to the block etc and do the rest of the recommended internal oiling system mods.

It's a nice upgrade to your oiling system.
