After about a month of working on this stepside GMT800 Silverado, the engine is back in, its running, and after today, it'll be ready for tuning. In this episode, I add 2005 and newer silverado electric fans while keeping the AC operational just like the factory intended. This requires an additional sensor to let the computer know what the AC pressure is, so it can control the electric fans when the AC is engaged. The 4.8 LR4 in the stepside features a 220/224 cam, a new oil pump, Comp 918 beehive springs, LS7 lifters, BTR trunnion upgrade, all new gaskets, ARP head bolts, gapped rings, and a whole lot more. The goal to compare against is the 300whp Gen VII big block, and while I'm not positive we will make as much horsepower as the Uglytruck, I think the 4.8 has a fighting chance.
