NCAA basketball is over until Thursday. I will be able to see the relationship between the deck plates and the heads as to how round and straight the cylinders are.

The plates and the heads are real close, only a few tenths difference.

Better equipment = better results only if the operator is skilled and experienced. Jeff Taylor Performance is such a place. I went there with the liners everywhere, over .002 variation in places, the end result was the cylinders were round and straight and only .001 bigger. I got one more build or of my pistons.

I miss a lot from my youth, I’m sure everyone can come up with a punch line, but I miss my eye sight the most. After cleaning and inspection I decided to reuse the main bearings. I caught the light just right and the saw a piece of trash on the bearing that would not wipe clean. The bearing was starting to flake off. That would have been pretty after a few dyno pulls.

Is it a Polymer coating that was flaking? If so why did you re-use it?

I know there are many that have not experienced issues with King bearings and will vouch for them.
Due to the issues, others and I have experienced with King bearings, I have not used them since 2017. My "to go" bearings are ACL, Clevite, and when I can find them, Speed Pro. In 2017, we had issues with several Trophy Truck engines with King Bearings. Switched to Clevite and ACL and no more issues.

The pictures below are issues that some other engine builders have experienced with King bearings:
