....cool beans willy..just give it to me straight!...I been at work all day (working and posting)lol..yea I already was swaying away from it...if it starts to get too complicated...walk away... once I get those gears ill post...ok 2:30 cali time..im clocking out...thanks Stang brothers!There a difference in a 4v head and a 2v head. The GT500's are 5.4 4v motors. The adaptors i have seen are to adapt a 5.4 2v manifold on a 4.6 2v. The other thing is the location of the S/C pulley. It wont lint up with your 4.6 2v belt system. Someone would have to make a custom intake manifold or custom adaptor to make everything work.
Depending on what you want to do with your car I would piece together a centri kit for some easy, cheap boost. But personally I would do gears, headers, ect before boost. So you have the supporting mods already. But to each their own.
