Jack,
You mentioned the Kettering V8. I was not familiar with this terminology and looked it up. I was wondering if you would agree with the history given on this Wikipedia page:
en.wikipedia.org/wiki/Oldsmobile_V8_engine To me, it seems all credit goes to Oldsmobile, and I was under the impression that the 331 Cadillac was the original true "small-block" OHV V8.
It goes on to claim that the "small block" design continued in the large displacement Olds 425 and 455 engines, only because they had a higher deck hight for longer stroke. Well, deck height isn't everything, as there still needs to be adequate crank clearances.
So what's a "big block." Anything over 650 pounds? Or whatever you decide to call it?
