Scott I setup the 350 in my '72 Cheyenne/20 with TBI for inside of $400 (now over 400 but only cause I bought an emulator, chip burners etc). Netted me 2 MPG better. Local Upull yard sells transmissions for under $100, go pick up a used 700r4 at that price it'll justify its own cost real fast, especially for the older trucks that made up for lack of displacement/torque in ungodly high gearing.
