I've been working on a Belt Drive that still uses the factory cam sensor and phaser ring. I've been running one on my motor for the last 18 months and it's been flawless! I will be taking the motor apart soon to evaluate the parts, make any tweaks and then see if there's any interest to make them. The only thing, is you will need to run a belt driven oil pump, like a Petersen R4 Single Stage or similar, as the Belt Drive is exposed and a factory oil pump is withing the timing cover, driven off the crank.

Loose the distributor BS. It can't get any simpler with the Coil on Plug and an MSD 6013 Ignition Controller. And like mentioned else where, it is programmable!!
