You say you are going to do a lot of around town driving and no high speed driving and nothing over 55mph. Don't mess with a 700r4, just put in a turbo hydro 350 tested tried and true. The 700r4 is for computer engines that run slow, about 1500rpm. A carburetor engine needs to run above 2000 rpm to work well. Most people don't know this because carburetors were phased out in 88. A Q jet 350 and a turbo 350 are the perfect combination for occasional use and slow speeds around town. No wiring headaches, you can fix anything on it, and it is going to sit most of the time so why make thing complicated?
