Is the 4.6 Cobra engine found in any other Ford Product
 

I was told that some of the 1995-1996 Lincolns used the same long block assy as the Cobra Mustang. That the intake and runners were the only difference. Is this true? I need a Cobra engine for a 99 Mustang and hate to pay $6500 for one.
Secondly, is it difficult to swap a 3.8 to a 4.6 in a 99 LX.
Third, will a 5.0 go into the 99 LX without extensive modifications to the motor support towers, or will it bolt up by just changing the motor mounts.
Thanks for the help.

Only the Cobra has the 4 valve 4.6 all others are 2 valve. I would think that a Cobra 4.6 would fit in there with out needing to much stuff. I would think you will need some difirent wires for the new Cobra 4.6.
