I'm building a pulling garden tractor with a 68 cube 3cyl turbo'ed engine as I have posted some questions before about. I did a search and I see on Cummins builds it was recommended .007-.009" on daily drivers and
.015-.020" for piston clearance on dedicated pullers.
I have seen for gas engines they normally recommend so many thousandths per inch of bore size. My engine is only 78mm bore compared to ??? on your big cummins motors. So I'm looking for a similar rule of thumb for hot diesels.
What is the bore size of a cummins? I could calculate from that.
Is there a similar rule of thumb for ring end gaps?
