Back in the olden days short stroke engines were very common (a 302
was a 327 with a shorter stroke).

Those really aren't representitive of the "olden days". The old,
straight 6
and 8 engines had relatively long strokes with small bores ...

I was referring to the performance engines of the late 60s when power
was the only real goal. The 302 was developed for the 5 liter racing
circuit (Can Am?)

Gotcha.

But the 307 was a dog of a Chevy engine. Under square. A 302 (305) CID
engine was a 327 with a265 CID crank. Whereas the 307 was a 265 with a 327
crank. The reason for Over square on high reving engines is to keep down
the ring speed.
