Running a crank trigger and MSD 6a Ignition
I picked up a MSD 6A box on craigslist for cheap. Supposedly rebuilt at factory.
The MSD 6A box has a lead for a crank trigger. I have the crank trigger wheel and magnetic pick up from the 5.0 L explorer. This got me thinking about using a crank trigger for the stock distributor.
I have the magnetic pickup and EDIS trigger wheel from my explorer motor. I need to use the bronco front cover, balancer, and pulleys -but the explorer magnetic pick up bolts right to the bronco front cover in the same location as the pointer and I think I could fab/machine the crank trigger wheel to the bronco harmonic balancer. This seems like this could be fabbed to work but:
If I did this and ran the bronco distributor and coil but used a crank trigger, am I going to lose all the stock ignition advance features of the TFI and bronco EFI distributor? Is this a big deal, as some people run with the spout removed? Or will the computer advance the timing as needed using the crank trigger?
