Finally got the rotating assembly done yesterday! Put in those new King bearings in the rods. Plastigauged everything and got .0016-.0020" so that's all good. Everything turns over smoothly and looks great.




Pretty darn sure it is zero decked. This is it at the top of the stroke.


And I put a straightedge over the the piston on the deck and it didn't touch while rotating the assembly.

Next up is the head when I get that back from Tom.



Anyone know what this hole is right here? It's on the driver's side right below and toward the rear of the freeze plug. Coolant or oil?


Also anyone know what these are? I'm pretty sure they're ARP head studs because the bottom thread fits the head and top says ARP haha. The machine shop gave me back 3 with my pistons and I'm not sure why.
