Re: Attempting my first build 72 K5

Unfortunately, I ran into major problems with the engine that came from West Coast Engines. One day, I started the motor and heard a loud knocking noise and checked to see what was going on and noticed a big crack in my valve cover.

After pulling the engine and taking it apart, we noticed several problems.
1. Camshaft damage
2. Signs of Detonation
3. Obvious sign of head gasket leaking
4. Cam bearing having excessive wear (1500 miles on this engine)

Bottom line I don't trust this engine and I refuse to slap bandaids on it. I have local shop building my new engine.

We are starting with a Dart SHP small block 400 with 350 mains. It's going to be a 427 stroker mated to a 4L80e. The trans came out of a 2000's Yukon 2500 series 6 Liter. I have another local guy building the transmission for me.

I am going to start an engine build thread in the appropriate section so in case you all want to follow it, I'll post a link to it.
