Yep took out the three speed and replaced it with a 200-4r from an '89 Oldsmobile station wagon. only mod was to move the trans mount back, even used the same driveshaft. Really made a huge difference in the 250 6cyl. Went from 55-60 to 75-80 comfy cruise speed. Just made a trip from NC to OKLA and back. Awesome. Only thing that could have made the trip better......Air Conditioning! soon to come
