Twenty-four valves, six individual throttle bodies, and a 3.2-litre straight six that runs to an eight-thousand-rpm redline. The S54 landed at the tail end of the era when a naturally aspirated motorsport engine could still be sold to the public with a warranty on it — no turbos, no assistance, nothing between your right foot and the cams. Here it is drawn as a technical study: cam cover, front accessory drive, the row of intake trumpets down the side, every line laid in by hand under a 3.2L INLINE-SIX header and a blue-and-red stripe.
