You think you have seen most of the characteristics of the 216 inline six cylinder of the early Chevrolet years then up pops something that you have never seen. What was the reason for an identical engine number stamped on the same block, on the same side, about 9 “apart?
While visiting Jerry’s Early Chevy Repair Shop in Independence, Missouri (816-833-4414) we noticed this double stamping. The 216 six cylinder had just been returned from a degreasing and reboring of the cylinders. Thus, this 1946 block was perfectly clean so the numbers were all exposed.
NOTE: The normal engine number, as we have seen, was on early Chevrolet six cylinder blocks beside the hole for the distributor. However, this engine also has the same number under the side plate gasket! It is not seen until the gasket is removed. See photo.
Why would a Chevrolet engine factory take the extra effort to stamp this number behind the side cover gasket? So unusual. Any suggestions are appreciated.
Yes, we thought a law enforcement person could see if the original numbers by the distributor had been ground off and re-stamped. However, certainly much extra effort taking a full side plate off a 216 engine block to see a factory number was not for a roadside check!
The usual place for a 216 and 235 stamped engine number
A surprise find. The same number on this block was behind the side plate gasket.
