Interested in the project but probably too much of it is over my head. We have hypothesized and gathered parts from a Jeep 4.0 EFI, including harness & computer, to fit to a 250, and perhaps then to the SOHC 6. Not far along. Clifford intake machined for injectors. Modified dist with Jeep cam sensor that should work. I am a distant "neighbor" in Gardnerville, NV. Enjoying your posts! I have a 1938 Pontiac 4 dr, with a 1968 Firebird "Sprint" OHC 6, with 200 R4 fitted.
