Just purchased a '64 Impala SS as a hobby driver. Trying to nail down exactly what engine has been put into it. I've got a good idea from research . Here are the engine numbers -- Code F0128CD (and yes that's a CD) Casting # 3789935
It also has Double hump heads and a 4 brl on it. I think its a 1961 283 from a corvette. Let me know if I've got it wrong. Thx
According to Alvin Colvin's by the numbers it was installed only in a Passenger car (full size not a Corvette) in front of a manual three speed with an over drive during the model yearts 1960-'62 rated at 170 horse (no camel hump heads) or 1963 rated at 195 horse (camel humps were a posibility).
