F3 Engine in a F2 Frame
Okay I finally gotta hold of a F3 engine. So decided its time to go ahead and start putting this thing back together. Now I am reading conflicting things. My goal is to use the F3 engine with the F2 carbs. My understanding is that I will need F3 harness and ecm. I read somewhere else that the F2 and F3 harnesses are he same as well as ecm. I still plan to use the speedo for the F2. Can anyone provide some info on what I need to actually do here. I would greatly appreciate it.

The F3 wire harness has the throttle positions sensor that goes to the carbs, where as the F2 does not. And the F3 has a little different ignition timing or cam timing. Get yourself a F2 manual and F3 manual and compare the timing issue. I would think that if they were the same or very close, that it wouldnt make that much, if any difference. I would think the F2 harness would work on F3 engine w/ F2 carbs.
