I have an interesting block.
The casting number ends in -5911 which is indicative of a late '53- early '54 235. It is wearing a CAR bellhousing and a a smaller clutch assembly. It is a higher-pressure 235 with NO Tenneco sign-shaped oil plate, has the old high water pump of a 216, and had a -5913 head with the 4 valve cover screws. It was originally painted honest-to-goodness BLUE... not grey, not light blue, not orange etc. That blue still shows on the block in places. The original valve cover is here too and it is the later 235 type.
The engine serial number is kind of indistinct (poorly stamped) but it appears to be
Vinbuster returns this as a 235 built in.... 1960 , no less, in Norwood OH.
An old-style water pump block THAT late???
Replacement engine, or dare I say... Corvette?
