thats a PATC turbo 9" raptor converter, was available 2000-6000 stall so youll need to pull and look for some marking and then contact them to find out what it is
It might have some numbers on it that can be a clue as to what's inside. If it was built for the V6 it's probably similar to the 9" Art Carr's which worked well. A 9" will spool easily. They need to be built on the tight side to couple power of a 9 or 10 second car.
