This thingy?

It is an electric piston ring trimmer. It's used to custom fit rings by adjusting the ring gap to the desired measurement. For years we used the hand crank method but this little tool allows for incredible accuracy and speed as well.

Yes, that. Cool tool.

True engine porn! Looks amazing.

Very cool Henry! A VERY lucky guy is getting that engine!

WOW , thanks for sharing Henry. That is just beautiful.

Very cool! Quick question if I might, Henry? I don't think I've ever read about this mod? What's going on here?

He is drilling the case for the cross-drilled crank. Notice the larger oil galley hole and the grooved bearing on #5.

When we cross drill the crank (a mod that adds oil flow to the crank to feed rod bearings #2 & 5) we groove the bearing for constant oil supply. We also increase the volume of oil to the bearing/journal by increasing the diameter of the feed hole.

Some people groove the crank as illustrated on our SuperCrank but for street use we find grooving the bearing easier.

Nice! I did notice the bearing on #5 was different. I just wasn't sure why the case mod. Please keep it coming. I'll be working on my case soon. Need to get a sealing kit from you , Henry. Will call...

A small correction just for clarity: the modification in this engine is on the # 4 main bearing.

Jim is correct. The bearings are counted from the flywheel forward with the thrust bearing bearing # 1 and the nose bearing being # 8.
