So long story short, were doing a y block swap into a 56 ford with a 223. Its a 56 fairlane y block that's been rebuilt and should not have a problem going in. I just want to make sure that before we start the swap, that we have everything we need. We recently acquired a fordomatic out of a 59 or so truck. It has the external cooling lines, the non finned torque converter, and the truck type bellhousing with a vent on the top and side. It also has the mounting points on it. So the main questions are, are the 223 and y block torque converters the same, will the truck bellhousing work, and if they aren't the same, where can one find a finned torque converter that doesn't cost an arm and a leg. Thanks guys!
