Anyone know the correct interference (press) fit between the connecting rod and piston pin bushing? This is for the 265 flathead I'm building, but I think it would be about the same for all the flatheads.
Some bushings were bronze (or brass), while others are bronze/brass over a steel backing, so that could make some difference in the fit.
Also, should the bushings be burnished then honed to final size? My manuals say nothing about burnishing them, but I see folks online saying burnishing is really the best way, though they are not necessarily talking about our flatheads.
