This engine is a solid beast. The old guy needs some lovin’, just a little more than the normal rebuild, to bring it back to it’s glory.
Inspection, Teardown, and Cleaning.
Block Work: Bore, Hone, and Deck the engine block.
Head Work: Since this is a Flathead, all the work will be in the block, so Clean, Resurface and Paint the head.

Machine Work- Recondition Crankshaft, Camshaft, and Connecting Rods.
Order New Engine Rebuild Kit and Parts in correct sizes.
Last step, assembly!
A few shots Before we start any work. I love the Before and After comparison.
These are the down and dirty shots.
The head work is easy peasy on this Flathead. Clean it up, Resurface to a flat surface to mate up with the block. A second clean, paint it this cool red, add black touches to the casting letters, and we’re good to go.
We cleaned this bad boy up and it revealed some additional work is needed. The valve guides are shot, we need to install new valve guides, check. The valves are in bad shape, new valves on the order list, check. It needs some new valve seats installed, check. Bore and Hone the cylinders leaving a good finish with proper crosshatch. Second clean in hot tank to remove any particulates. Deck the block surface so the head mates up nicely. Last we put a coat of primer, then a few coats of paint.
