Hello all! I have a mint, custom built 1977 CJ5 with a 1978 231 even fire V6, Th400 tranny complete with ratchet shifter and shift kit, custom frame, and original, beautiful steel body. I had the engine all rebuilt 2 yrs ago, and probably have about 1500 miles on it. It has a kennebell 4 bbl intake, w-a holley 600cfm carb. It flies like the wind, but there is no doubt I'm pouring the fuel to it, and wasting money, and compared to throttle body, losing major performance. My question, to you guru's is does anyone know of an engine I could easily find, and salvage what is needed to swap over to efi, or should I break down and spend the big bucks on a premade, ready to install kit? It has a temp sensor, and a plug on exhaust manifold to install an 02 sensor, but does not have any spark knock sensor. Any ideas? Comments? Suggestions?
