Totally cool man... My gear drive /408 stroker is for a street car, where I'll be putting thousands of miles on it...With an electric fuel pump....Think of how many millions of cars out there on the road with electric fuel pumps....They seem to be running just fine, and with thousands of miles racked up on them...lol So I think I won't have any issues with that.
This is the unit I used...

All I had to do was drill one hole in the block for the mounting bracket. Set the backlash for the gears and mounting plate, and set the timing as per the instructions. It wasn't too easy, I had my brother help me, but it was kinda of a pain in the ***...
