Unfortunately, if the mains are shot you probably need to have the crank turned. Just replacing the mains will not really solve any problems.

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.
