And....here are the pistons back from cryogenic treatment and thermal coating.....


No fly cut needed for the 11.5:1's with the cams I have. Plenty of radial and PTV clearance. This thermal coating is good to 2700 degrees farenheight which I will hopefully never experience.

And here they are, happily nestled in their new home:

I should mention, I went with ARP because they are cheaper than OEM and they are manufactured to a better spec. It's not necessarily that they break, it's that they distort under load and can lose tolerance. The ARP's hold the tolerance on the big end better. I run pretty tight oil clearance so in my case that is very important, but for any motor at 10k it's critical; in my opinion.


RC51 Trans is well underway...

A beautifully polished crank that has been balanced to the new slugs.

Hopefully, this is the last time I have to do this for a while...here she is.


Looking at this photo reminds me that I'm short by one 6mm bolt. I better order that.
