McCulloch Piston Chart - doug tenney - 03-04-2017 I saw today on FB that Steve Miller is rubbing together some old Mac parts and seeing what turns out. Yeah, I know that's nothing new, but in this case he asked about piston dimensions: "mc6 stroker piston questions . putting together mc6 with a 7 crank have friend might have correct piston except were not sure what to look for ..anyone have pin height or from dome to first ring land ..specs ..can we see by eye the differences ..?? also lookin for mc10 stroker crank" Turns out that Scott Kneisel made a chart last year, which he posted on the old forum (RIP). (Dave Luciani may have had a hand in it, or may even have his own chart.) Anyway I posted it here. Thanks, Scott! tap chart pix to enlarge RE: McCulloch Piston Chart - Ryan Johnson - 03-04-2017 Thanks Doug and Scott! I was wondering just the other day if something like this was available.

They are thin. Figure this out before you confuse yourselves more. Mc-10 Power Kit Piston P/N 48833 (std. bore) Mcculloch specs. Oversize are the same plus oversize. above top ring - 2.1165/2.1170 below top ring - 2.1190/2.1195 bottom skirt - 2.1195/2.1200 The Mc-5/6 head gasket was increased to .080" in production line engines using P/N 48816 head gasket to reduce combustion chamber temperature. |
