Undersquare vs. Oversquare Engines

The 400 B engine is oversquare, the bore is larger than the stroke. The LA stroker is pretty much square in the configuration that I gave. it would be undersquare @ 426 with a 4.125 stroke.
thanks for the correction. but you said 408" on both so......
a better comparison would be 408 mopar smallblock vs 408 chevy smallblock.
