bellhousing/engine mounts.....
after reading teh bellhousing/starter thread, and looking at all the pics, i just remembered a question i had about bellhousing to engine mounting holes, small blocks in general,, but i'm interested mainly in 283's...
i have a 67 block, was out of an automatic car,,, it doesn't have teh top center hole drilled and tapped,,, anyone know when that was changed? was it just for automatic applications, or did chevy stop drilling/tapping all blocks on a certain date?
thanks....

Top center hole
A lot of bell housings also do not have that top center hole drilled. I bought my 621 bell housing brand new in 1989, and the top hole is not drilled for a bolt.

I don't recall when/if that changed, but it didn't have anything to do with manual vs. automatic transmissions; the Machining Department at the engine plant had no clue about what transmission any block was going to use - they were all machined the same at any one point in time.
well, it did end at some point,,, the manual vs. auto, makes sense...
i guess since they stopped drilling/tapping it, its not necessary...

was something attached at the right side, old front mounts, in some 64 small block application?
