[Tigers] overdrive toploaders (more)

[Thomas Witt]

Someone please correct me if I'm wrong.

>>>I wonder what kind of weight savings you get with the aluminum case?<<<

I think if you run the aluminum case it has the wide mounting ears only. 
And if you are running a 260 or early 289 the stock bellhousing (5 bolt) 
will only accept the narrow ears.  Thus, you need to find a special unibolt 
(5/6 bolt) bellhousing that is only available in cast iron (?).
 It could leaves you with the option of either and aluminum case and a cast 
iron bellhousing, or a cast iron case and an aluminum bellhousing. If you 
run a later 289 or a 302 it shouldn't be a problem.
My understand is that the gears are all swappable between any case.

Going from memory here so please correct if needed.
