Ragtop, YES that is a good deal. However some junkyard TH400s probably go for $150 and up, so it isn't a once in a lifetime deal. Pull the pan and make sure it isn't scrambled. Otherwise buy it, have it gone through and sell it to make some good bucks or keep it for a BB car. I bought a good condition used one for $300. I think I could have done better, but am hoping this one is in as good a shape as the guy promised so I can run it as is behind my BB. It came from a 68 BB Camaro. I have since read that the early (64-67) variable pitch TH400 is noisy and more difficult to rebuild, so look and see if it is a 68 or later, which are all fixed pitch. If you send me the stamped code off of the tag, I can tell you what car/engine/year combination it came from.
