Painted the block, had a lot of trouble with getting good adhesion with the VHT engine paint, and I imagine it will start to flake after it's run-in for a while.
Sent the cab off for sand blasting, thankfully no major surprises.
Towed the cab to my work where I had it epoxy primed.
And bought a bunch of aftermarket sheetmetal (hood, fenders, doors, core support). Which I regret doing, as the gaps are poor and are going to require a lot more work to get nice.
Some progress on the motor
My favorite part! Borgwarner S480 kit from KBracing, specifically made for the 67-72 C10.
Had to mock it up after wrapping the hot side.
