OK--

The 1900 was 86 mm bore by 82 mm stroke.

IIRC, there were both 67.5 and 68.5 mm stroke cranks around for things like
GTA Jrs.,  a 1500 cc marine racing engine (again, built to some class
displacement limit) ---etc.

BUT--86 x 67.5 gives 1568 cc, and 86 x 68.5 gives 1591 cc.

Suspecting that this might be the story if somebody was trying to squeeze
the 1900 4v head into some particular 1600 cc racing class---

Again, IIRC, the 1900's came only with guillotine throttles and Spica, but
mebbe the same class was restricted to carbys ??
