1985 Chevy K-30 Military CUCV 1-1/4 T 4X4

Finally completed a monster rebuild project here in Maryland, and wanted to upload a pic to ya to work into your reader's truck section.. It's a 1985 Chevy Military CUCV K-30, equipped with a 6.2L 'J' engine. The engine has less than 5,000 miles on it as pulled from the truck prior to a body-off frame complete rebuild. I added a Banks Sidewinder Turbo system and 3" Banks exhaust from Diesel Injection Service in TX. The 4.56 gears and the Turbo make for UNGODLY torque and towing power from this beast. I added factory air conditioning and velour dash for the custom touch.

I have to say thanks much for all your help in providing me with the best in information on engine reconditioning before placement back into the chassis. I had to buy four of these trucks at a government auction in order to get my hands on it, but it's made spare parts sourcing very easy.
