Vortech and 10#'s of boost cost the 'ole 4.6 it's stock life. I'm thinking of going bigger displacement and turbo. I read of a fox guy who threw a navigator motor with 4v heads (nice little internal package too) and a 88mm turbo all together and made 713rwhp at 13#'s. What am I getting myself into here? Purpose is biggest bang for the buck (obviously). Suggestions on whether a 5.4 DOHC swap would be worth it or just go the shortblock stroker direction? Best strokers I've seen were 5.1L, which is fine too, but carry's a price tag of 3-4k depending on where your looking. I've seen junked cars with worthwhile blocks and heads for around a grand. What do you guys think?
