1969 327 2 barrel 235 hp. Google it.

 

The 3956618 block was used in 69 for the 327/235, but also the 350 in 250,255 and 300HP versions. The CE on the pad denotes Chevrolet Engine or Counter Engine, so it was sold as a replacement engine. If the heads are original, it is not a 327. Short of a tear down, a look at the crankshaft flange will determine the displacement. I don't have a picture handy, but each different stroke crank has a different shape to the flange. 327 and 350s are similar with the 327 having rounded corners and the 350 is more squared off.

 

Thank you. The engine was removed from a 61 Corvette.

They are all vette engines.
