Got a new Truck (new to me)
For myself on the ‘91 W-150 my son was driving, I wired in a MSD ready to go or you can do a MP Chrome box or the like. Let the OE distributor connection just hang there.
I also didn’t disconnect the OE computer. The wiring was backed up already for the injection. When I ran the carb, I used a Edelbrock fuel pressure regulator and made my own fuel lines to counting the return. EZ stuff.
