Today we take a look at my father's L78 396/375HP from his 1970 Chevelle SS that has sat disassembled since before I was even born! I would see this engine on a near daily basis during my childhood sitting on a workbench in the basement. This engine is the reason I went and found a Chevelle of my own and it is time to finally put this thing back together! First, though, we need to get to the bottom of what we have and what can be reused in the build.
