Here is my bagged 78 GMC Sierra Grande. 6500 pounds of pavement peeling awesomeness. 1/2" lines and valves all around running two 444 viar compressors to a 5 gallon reserve air tank, truck is run off of nitrogen primarily. She'll jump pretty good. still ahve some more bugs to work out as far as re-construction, I bought the truck half done with the c-notch already in place and a fedw other things so alot has to be re-done. I have a rust-free bed for it along with new fenders and a hood, and a driver and passenger door from a suburban with power windows. Anyway, here's some pics, along with a rendering of how she will look in the future at the end I'll update this thread from time to time with prigress, I yanked the 454 Big block out in favor of replacing it with an LQ4/4L80E combo and eventually going to cummins swap it. well, the LQ4 decided to eject a rod out of the block the other night so now i am shoving a 5.3 in it. More pics to come in the near future.
