Why Do this Conversion

Parts List

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.

Building The Trigger Wheel and VR Mount

I used my drill press to drill the 4 evenly spaced holes in the trigger wheel. I lucked out because I basically eyeballed it.

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.

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.
