if it were me, i'd go for 94-95 5.0. but then he's not me. i used to sell car parts, and believe me the 4.6 is decent...if you can keep the intake from cracking.. but he should do some serious soul searching b-4 he gets a 4.6. i hope i didn't offend anyone criticizing the 4.6, but 5.0 is a much more reliable motor and parts are plentiful.
