Guys;

Here's something I failed to mention:

Scott/Pushers/Tandems,....The 6 o'clock Starter and MM style Bellhousing
can be cut-down in width by 3" as indicated by the yellow dashed lines
(See attachment).

Butch,
Would you recommend welding in a plate rather than leaving the end open.
My thinking is eliminating possible flexing and optimising stress transfer.

******Yes George, by all means, since the weight penalty is minimal after
adding a couple of Inspection holes....However caution must be taken upon
welding these plates on:

The preferred way is to cut the Casting, fit and weld the plates PRIOR to
machining. If this becomes an ordeal to do:

Fitting and welding on the Plates to a machined Bellhousing can be done,
providing the Bellhousing is properly bolted on a scraped engine rear housing
that has a good, clean mounting face on it......This is a job for a "PRO"
guys, somebody like Ed.......I personally wouldn't touch it with a 10ft pole,
even though I'm an above average welder (ARC, MIG, TIG and Oxy-Acetylene).

BTW Pushers, you can cut an add'l 1" off on the R/H side of the Bellhousing
if you want to make it narrower and lighter......(See attachment)

Butch

Paul;

You forgot to add the Attachment with my previous post......Here it is again.

Butch

Your right! Sorry. Are you going to do some 3D's?
