Actually no knurling on that deal. I think I recall 3 new pistons though due to something not being right on a few top end interstate runs when letting off and seeing the lil white sparks from the tail pipes.
Funny though as I do have a old knurling machine that I use when doing some vintage tractor work. Wont even mention the valve guide knurler, might cause too much excitement.
I must ask... I see this egge deal with 273-s often. What gives?
