4L80 in a '71 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 350 in my 2WD '71 but recently a 4L80 came up for sale at a good price and I would like O/D. If it is in fact the old mechanical type that he claims it to be would this be a difficult conversion to make? I'm expecting to just move the engine mounts forward.. seems like everyone agrees that's the easiest way to go? But what I have no idea about is if there's kickdown linkage or anything else would have to be changed aswell?
