Hey all, I've got a question, What year did GM's vehicles switch from batch fire to sequential fire on the 305/350 engines? I'd like to pirate an EFI setup to slap on a 327 and drop it in a 66 chevelle... Can the early batch fires be converted to sequential??... Thanks for the help, and please reply dirrectly to DStreich at Compuserve.com Karl Streich
