Bob Campbell General Chuck-Probably just a"typo", but when these engines were upgraded, the cylinders were "sleeved" down to a 28" bore; the stroke remained the same at 32" (not 22"). 1/24/2014 1:44:27 PM
Chuck Zeiler General Hi Bob, you're absolutely right, 32 not 22, thanks for catching that. 1/24/2014 7:27:16 PM
