1985 GMC Sprint Caballero Diablo

1985 Chevrolet El Camino GMC Sprint Caballero Description

This car is so rare that I listed it under El Camino so it will be seen. It is not an El Camino but its twin the GMC Sprint Caballero Diablo. This car is not original but is in the next best class which is Resto-Mod in that it has an upgraded suspension, drivetrain, motor and transmission. From 25 feet away, the car looks original. There are minor nicks and slight dents but nothing that stands out and the nicks have been touched up. This rod is for jumping in and enjoying without worrying about hurting it. Whatever you do to it, it can be fixed and enjoyed some more. This beast is not for a museum piece. The motor, stall, transmission and everything about the drivetrain are perfectly matched. It is not too radical as everything is medium-high pulling HP from many different sources. At Wide Open Throttle it won't shift into 3rd until 97 MPH, then it is like a rocket. The SSBC front brakes will stop this beast on a dime and they look good too. It is hard to get a motor this hopped up to generate enough vacuum to run power brakes and a/c without a racing vacuum pump but I accomplished this by going all roller gaining horsepower from many sources and running a medium cam. This is no paper tiger. A serious, insanely responsive build. Buy it and all you have to worry about is creature comforts and looks. The bare bones from the ground up work has been done. Also has a sprayed in Bed Liner!

The GMC version is the rarest of the El Camino's. It has been mostly garaged. It has total command of the road and handles very well.

It has approximately 80,000 miles on this engine. Call if you have questions 318-348-6308, Dave. The car had 49,000 original miles when I bought it and I put in a new speedometer when I upgraded the engine. The speedometer just recently quit working and I had been thinking about getting Digital Dash by Dakota Ind.
