I'm trying to research a 1961 Tonawanda (sorry) block stamping. On the flat machined surface at the rear of the block, just behind of the back of the intake manifold seal, facing up, is stamped "Y27". Nearby, there is also an "E" stamped in a different font.
Anyone have an idea of the meaning of those stampings?
Thanks,
Verne.
