  • Do 164 tooth flex plates interchange between 1977 351 Windsor and 400 Ford engines?

    I know the bolt patterns are the same and balance weghts changed on the 302 in 1981 to 50 oz from the 28.2 and that both Windsor and Clevelands used the 28.2 oz. What I want to know is are the dimensions the same from the flange surface of the crankshaft mount to the bolt mount for the torque converter and is the balance weight located in the same place on the flex plate relative to the bolt pattern.
