I am looking for a good tranny builder around the southwest part of the state. My c6 pump and front seals went out and created cavitation issues. I priced used c6 big block bellhousing trannies locally and I am either quoted around $800 for 1 off a wrecked truck that won't even have a new filter, or I am told a 351m engine is a small block like the 302.

Needless to say I am looking for a knowledgeable builder or else I am ordering from broader performance, expensive option and my wife points out I have spent more on parts than for my truck.
