I had an A-500 built and when I picked it up the guy gave a me a core converter. Turns out he built the trans with HD parts and I'll need someone to rebuild this converter or I need to know who builds a converter that will work for my project. I'm only looking for 2000 or so stall. It is a lock up converter and I'm only running a 300 hp 360 through it for now. Any and all help much appreciated.
