Reply to "4.6 3 valve install. 2008 gt. Anyone done one?"

Gentlemen,

I have been thinking of a 4.6 swap for a Pantera for some time, too. How about using a newer 4.6 3V out of a wrecked Mustang GT and get the Ford Racing Parts 4.6 3V installation kit that includes the custom-programmed computer, a simplified harness, a MAF sensor, and a drive-by-wire gas pedal? If you read the instructions for the kit, it works on standard 3V mod motors produced between '07 and '09. Quicktime will make a bellhousing for the application. You would need to work out coolant lines, fabricate headers and motor mounts, change to a return-style high-pressure fuel pump system, etc., but as I understand it, the Ford Racing Parts harness really takes the wiring and computer issues out of it (and has std tach outputs). I don't see this as being as expensive as it's made out to be. Sure, if you want 500 hp and custom components, I'm sure you'll shell out a lot more than what a good cleveland-based engine with the same power would cost.

Ford Racing makes "Hot Rod" camshafts for the 3V which add 30 hp to a stock engine, for an engine with a potential for 350 hp from a reliable package with an aftermarket to boot. Plus, the engine weighs around 435 lbs, dressed.

Does my thinking seem out in left field?
