Default Case torque

Here is a new one on me. The case is torqued using cylinder torque plates to ensure proper case torque and pattern. Sure is neat to see it come together.

Yes. There is an STC for sertified engines for the ney nozzel. Or for us experimental types, JB's positive cam lube jets.

Yes Gill I suppose it is. One item we will never know. Definately will go into the life 'headscratcher' bucket.

Default LOP?

Any further comments from the shop on the condition after all the LOP running?

Gil I went and looked at the rods again and I think you could be onto something with this. I have a special socket I've modified that makes it a better fit..

I didn't see it mentioned, but what was the verdict on the cylinders and LOP ops?

I have come up with another mod better than the Ney nozzle. I had an .025 hole EDM'ed in the center of the tappets. Puts oil right where you need it under pressure. Got the idea from here...http://www.claysmithcams.com/edm-solid-flat-tappet/

The bigger 540's with the high-volume oil pumps tend to leak on the top split of the case and yes running a 1/16" ball end mill just above the cam will relieve the pressure just enough to prevent that from happening. That trick has been around a while and it works great.
