So I have a 292 in my 59 F100 with a Ford-o-matic. I dont much like this transmission so I have begun collecting trans parts. I have done my research looking for the proper torque converter but I am still unclear. I talked to the guys at Ford-Y-Block and read elsewhere that the proper torque converter is an 11". I cant find an 11" torque converter for a C-4. I have found plenty of 10.5" or 11.45". Has anyone done this conversion that can give me a part number or at the very least verify which one I actually need? I know this is a common conversion so someone has to have the info. I have looked through a good amount of c-4 forums both here and at other ford forums and cant find the answer. i appreciate any info. Also if you have any nice to know info regarding this project please pass it along. I think when I do it I will do a build thread and include a complete parts list with suppliers and part numbers to help anyone in the future. Thanks.
