It's a Pontiac something based on the way the exhaust manifolds come off the head. Any stamping on it? Here's a good site for ID numbers.

Pontiac fer sure.....
look at the face of the block next to the water pump (in the pic) for the engine code. the VIN derivative is lower down next to the harmonic balancer. Hard to see most of the time.
That's the way it is on my '68 bonnie

The CI should be cast on the side od the block. Looks like a 350, 400 or 455. Pontiacs are great motors; they are torque monsters and are very dependable. The old Goats were fast as hell.
A little more:
Displacement ID's were cast in the side of the block starting with the 1968 428. A 428 was cast on the side of the block and in the lifter valley was a 28. In 1970 the 350 and 455 had their size cast in the side and a 50 or 55 in the lifter valley. The 400 also has the 400 on the side and 00 in the lifter valley, but not until 1971.
