I am in the process of developing a Megasquirt FI system for my '80 Mustang with a 429. I have opportunity to acquire an '89 Multi-port 460 intake manifold-complete. If this would fit It would eliminate a lot of work.
My heads are early 70's (D??? - something). I have been told that the FI heads are different and the manifold will not fit. When I look at Blue Thunder and other places I find no differentiation (except CJ - Boss).
Does anyone have any input - advice?
THANX

The intake and exhaust ports on the fuelie heads / intake have been raised a bunch vs the earlier versions. The intake is not compatable with the passenger car heads with out mods.

You will need to convert a victor to efi. The stock fuelie intake does not flow worth a tinkers damn.
