New Owner of someone else's start

Hi All,

New member here. I bought a project start from someone else and the maker of some of the conversion parts will not help with instructions. So I am here because this seems a merry bunch of go getters and otherwise communicative group

So far, I am tracking some bellhousing/cltuch/TBO potential issues that I may need moral support on. Potentially also need a 6spd conversion and I would rather send my money some where its appreciated if our resident expert is still pumping out parts.

Some photos of the starting point[You must be registered and logged in to see this image.]

Before I get too far down the "what does it have now path" here are some issues I am contending with:
- When they got the red car, it had the original 82 5pd LSD transmission
- They did need to replace the torque tube
- The motor was built and dyno run at 505 hp

SOOO one of my first contenders after I get the thing wired and running would be transmission choices. They set this car up as a racer buit I would set it up mostly as a street oriented car. I tend to lean towards a built auto for high horsepower but they spent a lot getting the shifter and torque tube set up.

Seems like the options are:
- Swap for a 86+ manual, would maybe be able to reuse the torque tube, axles, and shifter? ($4k??)
- Swap for a Z06 trans and modified torque tube??? ($4-6k???)
- Swap for built 928 4 sp Auto.... Do I need a new torque tube and axles again? Swap bellhousing and switch to torque converter?

Which transmission setup seems like to is the most power capable without going through crazy endeavors to make it work? The popular "other place vendors" want an arm and a leg for the conversion parts. I'm hoping our resident expert is still making parts. I hate to undue too many things that have been bought and installed by the previous owner... but the parts combo on it right now will destroy the transmission in a week.

Thx!

Torque is really the issue but i assume you have 400+ Lbft, so a change is needed.
I would go with a C5/6 transaxle; spares and aftermarket support are plentiful.
