For those playing along at home, this issue finds us wrapping up our LB7 Duramax short-block build. Last time around, we dropped our trashed engine off with the skilled hands of L&R Engines in Santa Fe Springs, California. The block was disassembled, cleaned, and machined before heading to assembly. L&R’s resident Duramax expert, Frank, then installed the crankshaft, camshaft, and associated hardware. Our build continues as we prepare the rotating assembly for installation.
