Of course, I know you like to stir the pot.
Got to think outside of the box my friend! Perhaps one of the vendors could create a body upgrade whereby the car is cut in half just behind the rear bulkhead and a 12 inch wide section of sheet metal is welded in all around (left, right, top & bottom), creating the "stretch Pantera". Afterwards, any motor would fit! V12, V10 you name it. Chrysler power, BMW power, Mercedes power, hey, you could install the same powerplant as the McLaren! dude! The answer for all potential engine modifications, the stretch Pantera! Plenty of room for a supercharger belt drive. Maybe even room enough for a Cummins diesel swap! Bigger is better, huh? What do you think DeTom? Would you be the first in line for that one? Why, I bet you could even eliminate the hump in the interior! Maybe it could become a dimple! Kirk Evans could market the bulkhead dimple kit. More room for the elbows, a place to stick your used chewing gum, stuff like that! Plenty of room for heat & sound insulation too, for those that want that luxury car quiet cabin ride. Or, plenty of room for the biggest oil cooler known to man. Yeah, that's it, the stretch Pantera!
Conversions could be 1/2 price for white Panteras!
