Name is Eric and I own a few of the 67-72 Chevy and GMC era now several in the past. Current project being a 68 C20 I have a extra 1/2 ton SB frame and plan to combine the two. The only reason for this being that i haven't seen one. I have seen 1/2 tons with 3/4 ton axles on 4x4 trucks but this will be different. The powerplant is interesting and really seems to work well. 72 350 4 bolt main .030 over forged flat tops Vortec heads machined for .550 lift clearance. If you get the oppurtunity check out the Edlebrock "Air Gap" intake. They really do work well across the band. Hopefully i will get my act together and get some pics online to share with everybody such as you have. These trucks are about all I do if anybody has any question for me I would certainly be glad to be of service. Hey does anybody have a 14 bolt diff carrier they want to sell!
