what kind of power do you want to make? The town car engine is Not the the same as a cobra engine. Cobra engines have different rods and crank.

I would first consider that , with Turbos on that motor would be scary . the only motor I would feel comfortable with a turbo on would be one out of a 2003 cobra. the prevoius years all has aluminum blocks and have had some trouble.

I Killed a 98 4.6l with 10lbs of boost.... definately pull it apart and beef up the internals.

It seems as if the 302 based engine would be cheaper to an extent
