Yes, but most of them were 260s and smaller! You're not as likely to find them around these days, either. The 6-bolt bellhousings (and blocks) are much more plentiful here. Of course, with Japan buying so much scrap, it won't be long before the Clevelands are all gone too!
1965 was the changeover from 5 to 6 bolt. My 1965 "x" was factory 5 bolt, but i have since converted to six. Incidenty, the toploader bolt pattern is also different between 5 and 6 bolt.
All Clevelands and 99.9% of Windsors are identical 6 bolt
There is no such thing...at least that is the official statement. My own guess would be that it is an early 289 upgraded with a 302 rotating assembly.
The best bet for a 5-bolt block would be to source a new block and rebuild it using a 6-bolt block rather than trying to find a 5-bolt bellhousing.

strange.....302w out of a zd fairlane the input shaft to the tranny was broken and thats when i found the later model c4's had 6 bolt bell housings they also had larger dia shafts too so the convertor was no go as well.
