Scroll down the pictures and look at the 12 cylinder engine block near the bottom of the page. Note the cylinder arrangement. Now I'm no automotive engine expert (just a back yard motor-head with an appreciation for 67-73 muscle) but the offset cylinder rows means that different pistons function at different angles with respect to the crank shaft, and it seems to me that means slightly different strokes and different lenght (and mass) piston rods for the different rows of pistons. That would mean some performance/efficiency tradeoffs for one row or the otheror both, but what the hell, its a 12 cylinder engine, who cares about efficiency and performance will still be ahead of the curve. Power:Weight will be good at least. Nevertheless, it seems a bit odd. Mabye I'm just up in the night, does it seem to be an odd arrangement to anyone else?
