Did not get any info on my 120r pistons as to what clearance to set them up at in the bore. Anyone have the specs?

Hey Ron

For reference I have a set of 22868-00 going in shortly & the piston to cylinder clearance is .0015 - .0025. Thats for a 3.875 10.5:1 forged HC piston.

I'm thinking more like .005 would get it done AND sound like the old engine.

:redrolf: Well at .005 it would be good for a flaming burnout right out of the box. I think I'll ease into the .005 over the next 10 years or so. Thanks anyway.
FSG, you know where , has the sheets posted in the bulletin section. All specs and part numbers.
