Default Crown Vic front end?

Was watching the guys on Gas Monkey Garage hack up a Dodge truck. They welded in a Crown Vic front end and it immediately brought to mind a long and intense thread here about "Mustang II / Pinto" swaps. They acted like they use them all the time. Anyone know if it would work on a classic Mustang? Technology has to be good because its from a "cop car" (that's what the TV said, and they can't lie on TV, right?)

Default Crown Vic

There is a pretty recent thread on this topic. Short answer seemed to be, fits nicely for an old truck, too wide to adapt to a Mustang

Crown Vic's are the last of the "full frame" cars. You can cut and paste frame to frame but not really weld the front half of a frame to a unibody car (Mustang). You can drop a unibody down on top of a full frame though. There's a company that makes such a frame for old Mustangs. Or was. I never saw the point of that myself.
Later model P71 (police) versions are very little different from civilian models. A heavier sway bar and stiffer springs. Both of which civilian equivalents could be had by ordering the taxi or "towing" package on a Crown Vic or Grand Marquis. At some point they had brake heating problems so police brake calipers got steel pistons when non-police got phenolic pistons (yawn, who cares). There's a P71 specific forum where they nitpick all this such stuff all the time. I've driven many a P71 "Interceptor" and if you ask me they drive and handle like wallowing pigs. Not impressed. Nice big front brakes on the later ones though. I expect the partial frame swap isn't a bad way to go on an old hotrod truck.

i'd rather swap a vette craddle than a crown vic one if going to all the work. there's a few guys on the F150 boards replacing their twin I beam w/ the CV stuff. that makes a lot of sense because it nearly bolts right on.

Doh! Missed that we were discussing the 2003+ aluminum crossmember swap-in. Not the cut+paste of the older Panther chassis. My mistake. That crossmember is indeed a pretty neat almost self-contained assembly. Unfortunately almost 10 inches too wide for an old Mustang with no practical way to narrow it.

I autocross my Grand Marquis seems M3s, 370Zs are about 4 seconds slower through the course than me. Realy built for open track so its off a bit. Still has all power options.
