Don't think the Accusump is a bad idea, but not sure it will solve your problem.
First, you need an
oil pan and windage tray that will keep your pickup submerged during braking, and cornering. Canton makes a 9qt baffled road race pan. Milodon (I think) makes an 8 qt.
Did the pump seize and break the gear. Usually, the shear pin on the distributor will let go if that happens. Did the pump ingest a piece of junk that caused it to sieze? Send your replacement pump out to a coatings shop and have its internals polymer coated with an
oil retentive coating. Then use a magnetic drain plug in the pan to collect pump eating pieces of junk. The Canton already has one.
As mentioned above, if you mismatched the distributor gear and cam, that will eat the gear. Roller cam-steel gear (FMS part). Flat tappet cam-iron gear (likely, the one that came on the distributor).
One of the engine builders here, Don Scott, takes all new roller cams and burnishes the cam gear with a wire wheel before installing it. Claims to prevent dist gears from wearing prematurely even when properly matched.
After this, for a little extra insurance, install the Acusump.
