lets bump this back up...

as I recall ( do not quote me) the larger 168 tooth flywheel does fit the early bell housing since it is the standard chevy bell bolt pattern....

Just tried to fit an 11" clutch in the smaller bellhousing and it wouldn't fit. I had to use the larger bellhousing for the 11" clutch. The flywheel hit the bellhousing starter pocket.

Starter bolting to the bell housing is an issue I had not thought of as posted by bobscogin.

My line of thought was a starter bolting to the engine.

There are different starters from a small to larger diameter flywheel

I am questioning the 400hp to the bellhousing tranny mounts.
Seems to me the tailshaft is gonna break if it is not supported at the rear.

Still using the original front mounts, or has it been changed to side mounts on the Engine??

Whew!!!

If you think you may need to go to a larger clutch----might I propose early-mid 70's 4x4 bellhousing?
If I remember correctly---my 3/4 was supported at the side on the motor, bellhousing, and transfercase.

An adaptor is available from McCleod (and others) to adapt the small retainer to the larger retainer bore.
Trans bolt patterns are the same (87 truck belhousing in the 59 Avatar)

Just more food for thought.

if you are using side engine mounts and a cross member , then any bell housing would work?
