[QUOTE="JKCOBRA98, post: 83446, member: 647"] [b]quick01snake:[/b] I know someone who put a DOHC 4.6 in his GT.. Nothing was required to install and run.. The only difference in the 96-98 and the 99-01 are the IMRC's. The 96-98 had IMRC's and the 99+ didn't. Yes these engines have knock sensors that the GT computer doesn't read but He had no problems with the stock wiring or computer.. He did however get a dyno tune done to maximize the performance. [b]TTAFB_SVT:[/b] The 5.4 will need a few things depending on how you go about getting the engine, shortblock/longblock, or complete Navigator engine. The intake can be purchased from HCI (Hamilton Clarke Industries). They already have the stuffto produce an intake that will fit the 96-98 heads.. These are the heads I'm using. They were the last time I spoke with them working on the intake for the 99+heads (DOHC). I however am fabricating/modifying an intake for mine. The motor mounts are the same. The 6Spd is your choice.

The only change is that the flywheel is a Cobra one as the bolt pattern is for the Cobra flywheel. I'm not going to upgrade anything in the rear end but if you are anticipating drag racing, I would upgrade some of the components in the rear end... Here is a link to a thread about all the swap.
