Yes, mine is from a V-8 motor and it's entirely possible the GM switched things in mid year. To go around the Hydraulic clutch system, the '64 230 bell housing worked just fine. Note: The rubber boot for the clutch arm was missing(they always are) so I searched the swap meets for a year until I finally measured the opening. There are at least 4-5 different rectangular/square openings all different. They seem to be off by a 1/4"-1/2".
I ended up calling Mid America Corvettes and asked them to measure the rubber boot. It ended up that a 1963 Corvette boot fit the 230 bellhousing. Go figure!
