After 6 months of sitting in my garage on jacks and wondering if it would ever move again, my sand rail lives! After replacing almost everything on the engine above the block, and a lot of the wiring (not to mention fixing a lot of half-assed stuff from the previous owner) it roared back to life tonight. I still have to put the new disc brakes on it so there's no movement yet, but at least I know the engine is still ok.
