Hey guys my name is Robert i live in Wasilla AK, Just bought myself a 68 C10 CST (sorta). Sold my 02 silverado 1/2 to do it, best decision ever. Anyways my truck is a 68 CST C10 cab with a 67 front clip, and it has a 4x4 conversion sitting on a 6" lift with 35" tires, block in back leaf in front. It's got a mild 383 stroker, 4 bolt, scat 9000 crank, speed pro pistons and cam. Not sure what head, they have a single traingular casting centered on the front of the head. TH 350 tranny not sure what internal components, and a NP 203 transfer case, 12 bolt rear with 3.07 gearing. Altogether a pretty solid truck.
