Thanks efi-diy, do you have more information on the price of an efi system, or know where to get info? It does have the HEI already and a reply I got from another of my postings said that the coils for the V8 and 6 are the same. I was thinking of maybe putting a six speed transmission, but I don't know how much trouble that would be. Does the inline 6 have the same bellhousing bolt pattern as the v8? I appreciate any help or suggestions.
