I have an engine identified by a member here as follows:
That's a 235 made between 1957 and 1962 for the passenger cars with 3-speed transmissions.
T = Tonawanda Engine Plant
8 = Month (August)
06 = Day
A = Regular 235 for passenger cars with 3-speed transmission
There is a tag attached to the block that indicates that it has been rebuilt in the past, bored oversize, crank ground, etc.
I never ran the engine but was told that it ran.
I don't know that it is worth anything but you can have it if you want to come to Wisconsin to pick it up.
