This is what happens when you run your stroked 90 13 laps around the yard with no or little oil. Not sure where it went but I do know it lasted for 13 laps. Waste of a great ported head, melted the cam to the head journal.

This is the product of that screw up, going with a bored and stroked 110 instead, waiting for machine work to get back from our buddy Roger. Will be eliminating the hi low case on this one also. Will add more pics when the machine work gets back.
