It's all in the details, sleep well!

Several things happening on the LS build front. Spent several hours cleaning the crank, set the main bearings and checked clearances with plasti-gauge. All checked out around .001” (spec range is .0008” - .0025”). Also checked the end play which ended up being .003” (spec range .0015” - .0078”).

Surprised to come home yesterday and see the new Sealed Power piston ring set on the dining room table. Went down and checked the top and second ring in #1 cylinder to see how they compared to the previous set.
Top ring gapped out at .020” and the second gapped at .022”, which is a huge improvement.

Good work Buddy

The rings picked up by the machinist have end gaps much larger than the OEM specs.

That is not a happy feeling...

 

[PabloCruise]

No, the gaps are much larger with these new rings

I am picking up what you are putting down...

Improvement, but still not in line with gap spec for OEM bore, or what Sealed Power is spec'ing, eh?

Did you consult Scripture for end gap guidance when bored 20 over?

So that screenshot is from Summit’s website. I have yet to find anything giving me a 100% answer that the OEM gaps must be mirrored when the cylinders are bored.
The other screenshot is a book I’m reading about LS building. The formula he has puts the “ideal” gaps somewhere around .017”. Out of the 8, I had one at .018”. The rest at .020”, I’m not sweating it.

Might as well keep posting here, the OP has been too busy waxing his bench vise collection to post pictures of his pig project.
