Does anyone know if the lower/upper intake assy from 89-93 mustang will bolt up to a '67 engine? I'd like to do the efi conversion but I was trying to avoid the complete engine swap. I've been reading about efi conversions, and it seems alot of people find complete donor cars for the swap and they swap the whole engine. But then i read on mustang plus website about their EFI conversion, where it seems they did exactly what I'm talking about - adding the intake assy from an 89-93, but it does say in their write up something about water inlet being a little different and then something about rough idle due to cam differences. So I don't want to waste time going this route if it won't work or the results are poor.
