" From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) " " I still wonder if the 4.0 isn't -really- 3 7/8" x 3 7/16" - 3.875" x 3.4375" " " ------------ " From: Frank Swygert <farna@xxxxxxx> " " Standard bore is indeed 3.875"! Most pubs round it up to 3.88", " including Chrysler's/Jeep's. The metric specs are rounded to a single " decimal -- 98.4mm x 87.4mm -- which comes out to 3.87401575" x " 3.44094488", so you're correct in surmising the stroke is close to " 3-7/16". 3.4375" is 87.3125 mm, so it's a bit larger than 3-7/16", " but not 3-1/2" (88.9 mm). 3-31/64" seems to be about right in English " fractional units... but suppose the stroke was rounded to 2 decimals -before- metric conversion? 3 7/16" -> 3.44" -> 87.4mm... ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
