Be sure to check for bent rods. Also check the block deck and heads to see of they are flat.

Detonation

This wasn't the first motor I lost to a bad timing mark. The first build didn't have forged pistons so it was toast after 40 miles. The 2nd build lasted 700 miles...fingers crossed for the 3rd build!

I'd be looking for the correct balancer for the 327. They were much thinner and lighter. That 8" balancer might be stressing the crankshaft.

I would like to know which cylinders had coolant. I’d also like to know what valves were damaged, and a lot pictures.

L79's, L76's, and L84's all had 8" balancers

I always check the timing mark on a engine that I'm building using a piston stop before putting the heads on. I never trust it until I verify that it's correct. I even verify TDC on a running engine that someone brings to me for tuning using a piston stop in the spark plug hole.
