I finished taking apart the engine and I am taking the block to the machine shop in two weeks for cleaning and inspection.

As I am still looking for a cause for the oil pump damage, I did find some heavy wear to the thrust side on the crank. It looks like it has been machined down while the engine was running. This debris from the crank could have been what damaged the oil pump. This crank will not be reused.

Note: The piece of material on that bearing surface is just some material that I did not get wiped off at the time of the pictured.

I am going to have the machine shop price me out a rotating assembly for both the 3.79" and 4.00" cranks depending on availability. I already have camshafts spec'd out for both size cranks. Once I know the condition of the block (bores are very smooth with no wear ridge) and I know which crank, then I will get the cam on order while the rotating assembly goes back together.

Thanks for checking in!
