Thanks for the reply. I already found a lot of info on the web regarding this engine. I was hoping there was a visual inspection that would tell you if in fact this was a 406 engine. I'm thinking about buying a 1961 Ford Sunliner. The owner says it is a 406 c.i. with the tri-power set up. I know the 406 did not come out until 1962 and then only mated to a 4 speed. This car has a auto trans. I'm thinking the engine is probably a 352 or 390 with the tri-power set up. To be sure I'll have the owner give me the engine casting numbers and look them up. The owner insists it is a 406. I think he is wrong and just wants to sell the car. Thanks again for your help.
