Hi I have a good 3 speed toploader in my 73 250 and it's time to get it rebuild does anyone know of a good speed shop that can rebuild and build it up a bit? I know these transmissions are ledgandary but I'm looking at around 700hp for the new 427 going in. I found David kee but all he does is 4 speeds any help is appreciated thanks everyone in advance
