theres a site somewhere that sells a step by step instruction manual on how to do it. I'll do a search for it and post again if i find it.
I don't think it's extrememly hard, as the automechanics class in my old highschool put a carbed 289 in a 87 ranger, and those guys weren't very bright
I'd expect carbing it would be easier, but wouldnt it be cool to pop your hood and show your friends an EFI 5.0L in there ?
