I started considering this conversion when I switched my 1966 Bronco to Megasquirt. Having full injection when off roading is a must. With fuel injection you do not need to change jets or metering rods at high altitude. Now I have immediate throttle response and can stomp at any angle. I used a Holley-projection 700CFM throttle body.
I used my drill press to drill the 4 evenly spaced holes in the trigger wheel. I lucked out because I basically eyeballed it.
Building the Crank trigger wheel and VR Mount.
EDIS-8: missing tooth is exactly five teeth (50°) ahead of the VR sensor.
Having an extra timing chain cover made building the VR sensor mount allot easier. Most off this was just eyeballing. No formulas or calculations.

Finished Product
I was using an MSD mechanical advance distributor and 6AL before the upgrade. Now I can control timing curves through Megasquirt. I can also run much bigger spark plug gaps. The system is way more precise then running a distributor. I will be adding an MSD DIS-4 Soon.
