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.

Gto 400 big block or small block?
There is no such thing as a small block or big block Pontiac. Outside dimensions are all the same from the 326 all the way up to the 455. The only real difference in the blocks is the size of the mains. The 326-400 run a 3" main...while the 421-455 run a 3.25" main. If you are "comparing" it to say a small and big block Chevy.....dimensionally it falls in the middle.
