turbo 400 vs 700r..pro's/con's - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 71' SWB driver currently has 3 on the tree. I am collecting all the necessary parts to change over to AT. The engine is a 350 that runs very smooth and is perfect for an everyday driver. Question is do I put a turbo 400 in or a 700r AT??? Can someone that knows AT's tell me what the differences between the two? If it were your truck what would you put in? Just because I'm "old school" I'm leaning towards the th400, but don't want to not consider the 700r if it is the better way to go. Thanks!
