Go for it. I'll hold your beer.
Let me know if i can help.
I have the engine and t5 from a 88 turbo bird, if you need measurements of something. Good luck buddy.
and some FYI for you. Even though the transmission you have is most likely a world class unit, it still likely has the smaller 4cyl input shaft. Still will handle most anything a slant 6 will ever throw at it.
