273 Build

I took today off and spent some quality time with my 273. I miked the crank and the rod and main bearings for oil clearance. It's the first time I've checked oil clearance with a calculator and not plastigauge. LOL I checked for crank straightness and it was within a half a thou also. I also miked the pistons and bore for proper fit. That was pretty easy because the Egge pistons were within .0005 and the bore/ hone job from the machine shop was within a half a thou also. All the piston to bore clearances were .003 with one hole @ .0035.
(what's a half a thou between friends) LOL I installed the crank and torqued down the mains except for #3 (the thrust) and pried the crank fore and aft to set the thrust then torqued #3. The crank spins with ease and has .0065 end play.(spec is .010) Perfect! I did screw up though. I was file fitting my rings with a new filer and the end gap went from .006 to .018 too quick. I ordered a new set of rings. Better to be safe than sorry. I will snap a photo if I get a chance. Mike
