Engine Identification Help

Can anyone shed some light on this engine serial number I23I33 ? Looks like a 1953 262, but this does not look like the car matching serial number that is typically found on the R/H front side of engine.

304299 is for 51-53. 310110 is for 1954.

Thanks, I will check the casting number this evening.
