Tiny,

Acting on the information from the forum I scrubbed and scrapped clean the boss beside the distributor looking for a number. There isn't one. All thats there are the machining marks like I would expect to see from the flycutter when the boss was machined at the factory.

Either someone has ground off the numbers (although the boss is nice and flat) or this engine never had numbers.

I know from research on the body that the panel truck is definitely a 1953 3805 1-ton panel. It was originally configured as a bus with 3 windows along each side. You can see pictures at http://www.141.com/triumphs look for the link to the 53 panel on the left.

Based on the block casting number of 3764476 it appears to be a 1956 to 1962 235 ci engine.

I checked with the motor vehicle department here in Arkansas and they told me in 1953 they used the engine number for the title.

Kinda puts me back to square one since this truck has NO numbers.

You might say I'm at a loss as to what to do at the moment. eek
