How much does a pretty new 4.6L cobra engine go for?

whoa nellie!
From my Ford Racing Performance Parts 2004 catalog, page 171, 2003 Mustang Cobra 4.6L DOHC supercharged engine assy from throttle body to oil pan, 390HP@6000RPM, 390ft/lbs@3500, part # M-6007-SC46**
$11,999.95 I'm sitting a little lower on the wallet side just thinking about it! yeouch! Wait, did you mean 'pretty, new' as in attractive and right from the factory? Or 'pretty new' as in just a few miles on it?..... Significant difference there, I'm sure.

Pretty new as in installed, but not driven hard, and very few miles on it
less than 5000

I think your going to have a hell of a time finding a super low mileage 4.6 cobra engine. Anything that came with some decent power and a factory supercharger is going to be spendy and rare. Might get lucky at a large swap meet but I imagine your still going to pay 5-7 grand at least.

Just get a n/a dohc 4.6 and put a kenne bell supercharger on it. That is way better than finding a cobra motor. You might want a bullet proof bottom end in it though. I saw an 03 cobra that a guy put a kenne bell on. Dynod at 712hp 689trq to the wheels. ran over 30 lbs of boost. For a while then he threw a rod on the freeway.

4.6L Mustang
I am working on a manifold for this engine and bought a regular 4.6L (not a Cobra) complete 2000 engine for $1,600 out of a wrecking yard. Don't know how many miles are on it but it is relatively clean so I don't think it has all that many. My suggestion would be to get a standard 4.6L and put an aftermarket centrifugal blower on it like a Vortech or a Powerdyne. This would be cheaper....and easier....than trying to find a low mileage Cobra engine. Contrary to popular belief, there is no problem running a blower on a bone stock engine as long as you keep the boost around 7 psi. Seven psi boost on this engine is probably good for an extra 100 or so horsepower.
If you go this route, make sure you get a 1999 or later engine as they have better heads than the earlier ones.
