This 1985 GMC Caballero is for sale in Newington, Connecticut for $7,900. Under the hood sits a turbocharged 3.8 L V6 and THM200-4R four-speed automatic transmission from a 1987 Buick Regal Grand National. These engines were rated from the factory at 245 horsepower at 4400 rpm and 355 lb-ft of torque at 2000 rpm. The seller also states the hydroboost braking system, air conditioning, and probably 8.5-inch rear end was swapped from the Grand National as well.

This is a fine looking car from the outside. The interior is a little tatty, understandable for a 30+ year old car. The install looks like it could be factory from the limited pictures.
I hope the conversion isn’t recent as GM has a 3.6 turbo with about 410 HP and almost 400 pound-feet,
and a newer version 3.0 twin turbo with about the same numbers which are almost twice what they installed. The person that did this swap must have been a real G.N. enthusiast. Nice car, good looking build-out.
I agree with Texas.
