I have a 1955 Chevrolet with a 265 V8 that has some pieces marked as 'Made in Canada'. The engine was bought second hand in the 1990s.The number written on the block is very strange. I wonder if somebody knows if it's legit or made up by someone at some point....

It says:

I looked up the block casting # from the left rear of engine where the bell housing bolts on, if so, NO such number even close. Is the number you sent, the one that's stamped on the right front of block, below the right head?

Your engine is one of the three low compression (that's what GH suffix indicates) versions made of the 265 V8 in 1955 for overseas markets. Your unit probably comes from a 55 Chevrolet assembled in Mexico, perhaps Venezuela. Or one sent already assembled from the US to overseas market.

What you mentioned about a "G" I think should be a "C". It means that this engine was made in Canada. Both canadian plants: McKinnon Industries and Windsor Transmission Plant, used to supply engines (V8s and 6s, respectivly) to Tarrytown Assembly Plant, NY, for those units sent assembled to overseas markets, and to Bloomfield Packing Plant, MI, to be part of the CKD kits sent to foreign assembly plants, like GM Mexico.

I have found original V8 engines on mexican assembled 55-57 units that are painted not in the red we all know, but in the "blue flame" blue of the 6 cyls units.

Hope it helps.

Truck 265 engines were never painted orange but were the blue/gray color of a 6 cylinder engine and did run a lower compression ratio.
