OK Tom you do the pattern and work a deal with Tracy. It will
save him some machining time and a bunch of long 1/4 bolts not
to mention a few pounds. I will help with initial financing,
act as liaison with the foundry and provide some marketing
help through the news letter.

If it looks a bit like the Ross it should as Ross got it
pretty much right. All walls are .2 inch except where
necessary for bearing mounts.

BTW it loads the gear set through the back just like a car
transmission. It can be retrofitted with Tracy gear sets already
out there if someone would like to upgrade. Me for one.

We

think that this is a better position do to the heat from the exhaust

pipe

from the turbo if mounted at the 4:00 position and also it better

the engine.

Now comes the tricky part Richard. Getting all the bolts in there
and still keeping the casting pattern simple.

Well now, you guys are coming very close to the way the automatic tranny
13Brew and 20B engines originally were made. Just use their
bellhousings, a longer shaft, and a round adaptor plate on the nose (the
small end of the bellhousing) to fit Tracys. Use the auto tranny starter
and you are good to go.

Those parts are rare or very expensive if bought new.
We would like to use readily available and cheap parts.
