This is awesome! Are you going to repaint it school bus yellow?


Are those giant plywood head gaskets in the back of the shop? SBC and flathead maybe?

No 4 exhaust push rod was stuck holding the valve open. Couple quick taps and freed it up.

I once worked on a 305 in a squarebody that looked like the owner had never changed the oil, ever. It had turned to big chunks of crust between all the rocker arms, taking up almost all the open space under the valve covers. I chiseled it all out and shop vac'd the chunks and crumbs. It was all pretty much black like very dirty used oil.

I'm surprised to see how yours looks inside.. definitely neglected on the oil change intervals, but all that rust is wild. What's that liquid? Penetrating oil of some kind, I hope??

When I drained the old oil out I had to heat the oil pan to get it to drain out. Thick like molasses.
