Is a Pontiac a small block?
Depends on which Pontiac engine you are referring to. Any GM engine 400 cubic inches and under are considered a small block with two exceptions. The 396 is a big block and there were certain 400's that are big blocks. Two versions of the 400 were built.WRONG. All Pontiacs from 326-455 are the same size block externally. The only major difference is that the 326, 350, 389, and 400 have a 3" main bearing size. The 421, 428, and 455 are 3.25" mains. Now...if you are talking about comparing a Pontiac block to say a Chevy block....the Pontiac is larger than a small block and slightly smaller than a big block.

The 400 Chevy is a small block engine. The 400 BIG BLOCK Chevy does not exist! 402 big block Chevy does. it seems in the early 70s Chevy put 402s in their pick ups and they had 400 badges. this opened the can of worms known as the non-existant big block 400.
What horsepowertorque 400 Chevy engine?
Depends on the year, and what model it was installed in and if it is a big block 400 or small block 400. Need more information to provide an answer. The 1970-1972 400's are the most desirable motors to find. The early ones produced up to 265 HP stock. Chevrolet did not make a big block 400, i believe the other answer is referring to the Pontiac 400, as it is considered a big block. These engines can be torque monsters with the right setup. I have a 1970 motor with fresh rebuild and a single plane edelbrock torker 2 manifold. I have not dyno'd this engine, but it is great on the street and fries the tires in my 70 Pontiac lemans.
Can you put a Pontiac 400 block number 481988 in an 89 camaro rs and how would that be done?
No such engine as a Pontiac 400 Big Block. The back of the Pontiac engine block has a different bell-housing bolt pattern than the Chevrolet. Pontiac and Olds bell-housing bolt pattern match. Chevrolet and Buick match. Unless you have a dual bolt pattern transmission (GM did make them) the Pontiac engine won't bolt up to the the Chevrolet transmission.
