[PSB]

Fitting a 4.6 into a Cobra isn't the problem (...well it is a problem, but it can be done), it's getting the supercharger to fit under the hood. I guess you could just cut a big hole in the hood and leave the SC sticking out, but that'd look pretty tacky.

JBL is a great choice - wish I could have afforded one. I think I remember reading somewhere that JBL is working on modifying their chassis to accept a 4.6L.
