Still on to another 'W' big block, the 409, compared to a bored SBC 400.
The 400 is known for it's low end grunt...and how does that compare to the option the 409 gives you...excluding the huge handicap or cost to build.
Feel free to discuss other similar displacement between the BBC and SBC divisions.

Mmm, fascinating question I don't know the answer to. At first I thought it'd be almost completely a function of bore/stroke, but then I thought, hey, the heads and intake you can put on a BBC are quite different aren't they? I'm really guessing, but maybe back in the Paleozoic era before they had trick computer models for optimizing head flow, the larger heads and intake (w/ typically longer runners?) on a BBC would inherently tend towards better breathing and torque on otherwise similar displacements.
This is pure speculation on my part, but I'm sure BRUTAL64 might have some input on this subject.
