while talking to my brother about corba's today, and this combo, he told me that his farther who is a big mustang fan, 9sec street machine with a novi 2000, has a 99 corba motor complete from oil pan to intake, was this a good year for the snake, and woudl the block be aluminum block with forged internals, any links of for 90 gt swap for a 4.6, only reason I'm considering is because I could probably get this complete motor dirt cheap! what would have to be done for that kinda swap other than motor mounts, ECU and wiring harness I know there pretty big considering the size of 302, as far as cleareance in the engine bay

You would be a fool to pass that up. I believe that all 99+ cobra engines have forged cranks, rods and an aluminum block. I am not 100% sure about the pistons, those may only be forged in the 03+ don't take my word on that though. Even the most die hard 5.0 fan has to admit that the Cobra 4.6 is one of the best things to ever come out of Ford. With your weight you would be trapping close to Mach1 times, if not better. Throw a supercharger on it and you will be damn near untouchable. People pay a premium for the 4.6L 32v DOHC engine so if it is any less then $3,500 ****** it up now!! Whats he want for it? How many miles?
The '99 Cobra's had Forged Crank only. The rods and pistons themselves are nothing special and won't hold up to a lot of nitrous or forced induction abuse. They were rated from Ford for 320hp. See if you can find out what car it came out of and run the VIN to see if it had the "Fix" done. When the '99's came out, they were down on power initially and were recalled to have the exhaust systems changed, intakes modified and the ECU's retuned. Pretty much all owners complied, but if it hasn't had this done, it might be of concern. The exhaust and ECU probably wont' be a big deal to you, since you're going to be changing and playing with them anyway, but the intake manifold might not be a venture you want to tackle.
Despite what many have been led to believe, the 4.6L DOHC even with the aluminum block is still a pig of an engine. Heavier than any engine stuffed between the strut towers of a Mustang before it (Save for the '03-'04 Cobra) since the era of the big blocks. Take that into account if you're doing this with the impression that this aluminum block behemoth is going to lighten things up on the front end at all for you.
If you want the DOHC under the hood because you'd like a unique ride, then by all means take part in the swap. But if it's purely from a performance aspect, you're probably further ahead spending whatever you'd sink into the transplant in beefing up your current 302.

Good Info, Because he's like family and he brought if from a guy going through hard times I could get the motor complete for around 1500,mileage is right around 62k and it is aluminum, the only reason I was considering doing the swap was 1. the cost of the motor, and what kinda abuse the shortblocks can take. It would cost me the same to rebuild 2 or 4 bolt main bolt if not alot more just in the block prep work to hold that kinda HP rating reliably. 2. I could use an Eaton Supercharger, which you can pick up dirt cheap compared to the kenne bell. Unless you know of another EFI Roots, twin Screw Blower for a 302. I don't know of one. I could part my engine out, or sell it out right complete and cover the cost plus extras!

The relatively new thing used on HD Diesel engines to achieve torque throughout the RPM range is a variable turbo. Cummins Turbo Technologies (i.e. Holset) creates Variable Geometry Turbochargers (VGT's) that can change the amount of backpressure on the engine and can spool up faster or slower depending on the engine controls. Borg Warner and Garrett have been working on similar ideas where the vanes on the turbine wheel actually move to spool up faster or slower. I can't wait to see someone figure out a way to slap one of these turbos on a Mustang. Or better yet an aftermarket company selling these Variable Turbo's and controls for Mustangs.

Yup...the VGT designs are excellent. I know the ford diesels dont use them but they use sequential turbos...one small and one large. If you have ever heard one of these take off before. You hear the small turbo spool right off idle! The same principles apply with the VGT design...but all encompassed in one turbo!
A lot of the trucks that come through our shipping/recieving dept have those. Ditto on the sound. I love hearing those things spool when they start up.
