"All the V-12's workings can clearly be seen, from its pushrod-actuated tappets to the reciprocation of the connecting rods, thanks to a perspex window in the crank case. ... documenting Patelo's entire design and construction process. Assembling the V-12 is a fiddly tweezers and magnifying glass-assisted process and the attention to detail predictably stunning. With 1,220 hours of work into the engine though, we doubt Patelo is making many more tiny V-12s. "

Is it 4 banks of 8 cylinders?

OUTSTANDING piece of work, but let’s hope the President and the Democrats don’t get any ideas, if they see it.
