I don't build these bottom ends. I would hand a bottom end to a machine shop and build up from there. Honestly there's too much there that I wouldn't want to do in the bottom end. After that point, sure. I'd put one together for you. As for transmissions. I can assemble it, again though..the VB and channel plate would come from TEP. There's no better builder that I'm aware of for a transmission than TEP.
