Well, you'd get no complaint from me, if that was what I was going to
do. I am an honest man and would help you do what ever is necessary to
verify the motor is as stated. I am curious as to what you would be
looking for though. Since with two cylinders sleeved to less than
maximum displacement would you be looking to see if it is smaller and
farther into the allowed D displacement range? A pump check of the two
cylinders would certainly show that it is in spec. Check all the
remaining ones to verify? Or what? Or maybe just maybe this is so
insidious that I would over bore the remaining six to make it deeper
into the C motor size only giving away maybe 55 cubic inches to the C
class motor's maximum displacement. Yeah that would work.
You guys are funny!
