how do i make efi work on my 318?

If you want to run TBI, I would suggest a GM based system. The mopar TBI system wasn't all that great and there's little support for it now.

and the GM TBI system was good? Granted it was fairly reliable although I did make lots of $$ repairing them in the 90's, they are a pretty sad excuse for injection unless you put it on a firewood truck...1973 J-2000 pu with GM 350 TBI engine. It starts well but as far as any performance, consider it an electronic turd. Granted, it is better than the Chrysler TBI but thats like saying getting shot in the leg is better than getting shot in the chest....they both suck.
