Welcome North of 40 to the Stovebolt addiction. Lots of crazy things can and do happen to these old trucks in 60+ years. Since 47.2 - 55.1 trucks are fundamentally the same over those years there are lots of parts that will easily swap from year to year. Your truck is a Canadian-built 53 with a USA-built 54 235 block and a USA-built 53 235 head. Upgrading from the original 216 to a “full-pressure” 235 was and still is a popular swap. All / any 53-later 235 head will fit any 53-later 235 block. I had a 56 block with a 53 head motor in a 55 truck years ago.
Good job on the numbers research.
