people wonder what the largest displacement factory car engine was, here's the biggest piston engine, and the 2nd n 3rd biggest that I've come across

1910 Fiat S76, the "Beast of Turin", 28.4 liter engine that is about 1730 cubic inches, 4 times as big as my 426 cu in Max Wedge. Try and imagine 4 hemis, 3/4's a hemi, or 6 of the hemi cylinders per cylinder in this aircraft engined straight 6 cylinder. Yeah, that is huge, but made relatively little power or torque because engines weren't as understood and developed in the 1910's.An outrageous
