HISSMAN said:They are good, but I was made aware of an early test done with the GT500 motor. On one of the 5.4 test motors they used Terminator heads, with a custom lower intake and the M112 Eaton that is the same as what is on the Terminator. The engine power output to the flywheel was in the 430's. at about 9psi. I think this may have been to derive a base tune file for the new heads and blower using parts that they were comfortable with and new exactly what flow numbers they would be dealing with. Now, once they had the revised Ford GT heads, and new Eaton blower mounted in place of the terminator parts they saw about 480 crank HP at the same boost levels and same tune. This was around the time that they started throwing out the 475hp number that the GT500 would be ranked at. After some more fine tweaking they finally got the numbers to around 500 Flywheel hp. So, without changing anything at all in the tune or boost levels the GT500 heads and Blower alone are worth about 50 HP. This shows how much better the new heads and Eaton are. I would say that the heads were worth at leas 35hp of the total gain.

If that happened, I would definately opt for them in a swap. My ultimate desire is to have a swap kit available to drop in an aluminum 5.4 with the GT500 heads and a whipple 3.4 without having to do a lot of fabrication.

As far as I know the GT block needs modification, Ford might release an aluminum GT500 like they did for the Terminator?
Either that, or I'm lost.
But +1 to being interested in OP's idea. epper:

I like to tinker and figure things out, when I am done it can be closer to plug and play for anyone who wants this kit. it may not be equal to a stock GT in stock form but it can easily be made to out perform one at the fraction of the cost.

I'm in Ft. Wayne, IN and wouldn't mind stopping by and seeing this as well as talking to you about this project in a little better detail!
Hermann and Al P. are going to be bulding me one badass 5.4 as soon as I get the motor to them!

absolom said:i'm needing to put a 5.4 DOHC out of a navi in a 65 fastback, but i want a whipple on top good for around 600-700
we'll be rebuilding the engine with a stronger bottom end, but i'm still confused as to exactly what heads and intake i'll need to run
