Looks like a 322 since it has a harmonic balancer instead of a crankshaft pulley.

The final number in the serial number will tell you which model it was put in originally. The serial number is stamped into the drivers side of the block, in the center, just below the head.

Ya know, you will get faster answers if you post in the Buick Post War section of the forum.

I wish it was a 364 that would be ****! I am thinking this is a 322ci motor from a century. a 264 is a special motor.

I only have block casting # that go down to 1169334, however I do have head cast #'s that go earlier.

That number sounds like a casting number on a manifold or something. You need to look for the engine serial number which is located on a machined surface on the top outer edge of the left cylinder bank between the middle branches of the exhaust manifold.
