The VIN will tell you the year the car was made, whether it left the factory with a V8 or an L6 (but not which engine option), the assembly plant code and the six digits of the VIN that were sequential starting with 100,001. You already know the year and the sequence in that plant that produced it so the only unkown is whether it shipped from the factory with a V8 or a six. Look under the hood to determine that. If you find a much desired V8 (one that was factory rated at more than 300 horsepower) it will have the last six digits of the VIN stamped upon the engine's identification pad. If it doesn't then it will probably be a 235 six, or a 283, or a 327, or a 348, or a 409 as those where the engine options offered in 1963.
