For those interested here's the tale of my engine. Brent (lykinsmotorsports) was nice enough to set me up with a custom grind comp cam, intake, valve covers, etc. Once the parts arrived I took everything off to remove the cam, unfortunately when removing the cam the rear cam bearing fell out. Yes that's bad so after a couple beers I came to grips that the motor had to come out. I thought about scrapping the block but Brent steered me to at least find out what was going on.
The motor arrived at my local machine shop a few days later and during tear down we discovered the cam bores were fine. It seems the previous builder didn't align the
oil hole precisely allowing that bearing to heat cycle and loosen. We also found low compression Pistons were used. With this news I decided to fully rebuild the motor including new 11:1 Pistons, bearings, seals, valve job, etc.
I got the engine back last week and bolted everything up. My builder was nice enough to come to my house for initial start-up and break in. She sounds like a cobra should now. The block is basically now a stock 1970 4V quench with original spec 11:1, edelbrock intake and Brent's custom cam really woke up this motor! I'm happy I kept the Cleveland.
