ukwildcat53 Your Engine Cast # will be below and in front of your distributor like here ... The Engine Cast # will tell you when it was used in production... As example mine current engine is 3769716 and it was used from 1958-1962 and is a 235 CI ... Many of these old truck engines were replaced as mine was twice... Yours might be the original engine... Either way the Engine Cast # will be in the same place...

You can also run your Vin # through The VIN Buster ... Your vin plate is located here on the left side of your cab between the door hinges...
