Default 1962 2503 engine options

I just purchased a 1962 GMC 2503 which appears to be all original and solid. It has a 351 without any letter on the motor, the plate on the kick panel driver side is missing. Does anyone know of 1962 2503 being built with the 351 option or do you think it has been changed?

I suspect yours is a replacement engine. Your original engine would have been a 305. Your 351 is most likely a non-Magnum engine. You can find more info at https://6066gmcguy.com/351v6.html
