I've converted a few motors from carbs to injection. I usually go to junk yard and try to pull injection parts from similar motors, Like I did 87 jeep 4.2 motor by grabbing complete injection off newer 4.0 jeep motor with the head and all wiring harness, computer etc. One i just did about a year ago was a 69 dodge powerwagon with a 318, I went to junkyard and took throttle body injection off 87 ramcharger including harness, computer etc. It's a lot of work cutting all wires out of harness you don't need and just keeping the essentials. In both cases motors ran great when I was done but it ain't for the faint of heart, On the Jeep there was a lot of internet knowledge, On the Powerwagon zero help anywhere to be found. I've thought about doing same to My 68 02 but just want to find simplest way to do it, Thinking of some 80's throttle body of 4 cylinder 2 liter that's OBD1 which makes it less complicated
