SB vs BB who wins?

Well yeah, but compared to the Chevy big block, one could argue the Hemi was almost experimental. Every single Chevy big block got the same style head. Even on the W series engines, the 348 and 409.
Plus they didn't make enough for the average guy to have them.

Funny though I remember back in the day when mags would do a 460 vs 454 vs 440 it was always mainly between 440 and 454 and the 440 did come out on top for some of the shootouts but never too far behind.
