Remember there are two flavors of the C123 blocks. The late Super A/A1, SuperC, 100, 200 have the 3 7/16" lower sleeve opening and can go to the 3 1/4" overbore sets; the late C123 (ie: 130/230/140/240) are more the equivalent of a C113 with the 3 1/8" overbore kit installed at the factory. These latter ones can't go to the 3 1/4" sets like the early ones can. I haven't had a C135 block to play with yet but have assumed they are the equivalent of the early C123 with the 3 1/4" overbore kit installed at factory. They don't list as being the same part number though so there is some other difference, maybe a longer sleeve?

Dave, your C already has had the overbore kit installed in a past overhaul. Phil, the crankshafts are the same untill the x40 series when they switched to a different style water pump and front pulley with a narrow belt. That crank has a threaded end with a nut to hold the pulley instead of press fit.
