A999 as a street/strip trans.

Got it, I think.
Trust me if the 999 comes through, I'm sure I will be pestering you with pictures before we cut anything!!!
Only reason I asked if it had to be slant 6 or not is I am looking at a few "core" transmissions Wednesday that are like 4 hours away. I want to get at least one as a backup if the 999 falls through. they are V8 transmissions and I wondered if one of those would work is all.
One other thing for you to consider or research.
If this is a street car, a friend of mine who is also very torque flight knowledgeable tells me there is currently available a higher stall converter that is still equipped with a lockup clutch. I have never heard of that and do not know who makes it, but it supposedly exists. Maybe make some phone calls. This would be great for a street car. Supposedly some new technology.
