Yep Butch - it's (the pattern) very stiff now.
It will be poured this week.
While I've got your attention, my old engineer mate said that all openings
in the cast should have a raised (thickened) perimeter.
That has been done that for the bolt holes but I was wondering about the
starter snout opening and perhaps an inspection hole somewhere.
Your comments suggestions please.

You will notice that the pad for top starter mount position
is near the top of the tall side -however I can round that corner off and
reset the side M.M. to a hight similar to the shorter side - if that makes
sense to you.

What I'm saying I might be able to modify this particular pattern instead

of

making a new one, by modifying that corner.
Just a thought!

George,.......Please take a bigger picture of the complete Bellhousing's
front and rear and take a larger shot of the Starter-MM hump area.....So that
I can comment further.......There's no reason to re-make the mold from what I
understand you're describing...NO WAY!!!
                                               Thanks George.
                                                   Butch
