Hi guys...I have a '50 Buick Super that sits on a '65 Wildcat chassis (401;TH400;posi rear). I'm thinking about changing out the TH400 for a transmission that has an overdrive (700R4). Any info on what to expect, where to get necessary adapters, etc...would be greatly appreciated. Thanks!
Try Marty at nwspeedequipment.com. he is also a member of this board. They make the adapter and much other Nailhead stuff. There is another place if believe called Bendtsteds who makes adapters for nearly all engines to chevy trannys.
