One of my local customers did that conversion, took out a good 727 and put in a GM 250 4 speed over drive, lots of money and problems making it work and shift the way he wants it to. Two different converters and lots of labor so far and he is still not happy down
This went into a 1963 M.W. Fury with 3.23 gears, he said originally he wanted better mileage, it is a real nice drive to show car and doesn't get driven over 3000 miles a year. He later change the rear gear ratio from 3.23 to 3.55 to make it accelerate better confused
The parts and pieces cost a bunch over what he will save in fuel cost if he doesn't start driving it over 30,000 a year work
My message is be careful of what you do to your car to make it better shruggy
