Well, just looking around quickly on
www.car-parts.com, I can pick up a 6.0L for the same price as a 5.3, so it looks like it might be a better route. I looked on AA, but can't find an adapter for the Gen III to TH400, but I'm sure they make one, then after that it's an Atlas. TomH, what did the swap end up running you, if you don't mind me asking. I'm thinking $6-$7K?
