First pass, top of second gear, somthing let go, but the engine was still running. Took us a while to figure it out, but we lost the back of the cam...Pulled the engine out today. Might be going roller..... Last edited by Dragula; 08/18/13 04:05 PM.

The only other damage we were able to find were the lash caps. They took a beating. Just simply sheared the back of the cam off. Three seasons on that cam. The lifters lifted right out. Block looks good. I am sure we need a new cam bearing though....

At least the parts we know we need. Going to a roller cam this time.

Right now we are just looking to get a cam and a couple of push rods on order. Bearings and gaskets I think we have, and I am going to port match the intake to the heads while they are off. We might even put new rings and a quick hone on it, we will see. Springs also need to be checked, but they all looked fine, I didn't see any broken ones.

Drove it home on 6 cylinders. Pulled the valve covers #7 & #8 rocker were not moving. Required a full rebuild though.
