  I think the 350 should have two notatios, the bowtie 350 was quite
different enough to be seperated. It's Siamesed cylinders lead to the
400.

 What about the infamous 409?
Plus there is now the 502 and 572 in the Big block line-up.
These are a stroked 454 and a new over the counter design respectivly.
Other wise a good synopsis of the differences. I think some of the car
companies should REALLY get together to decide what the qualifications
are of a sb and bb. Ford has 4 distinct families, two of which are
recognized as BB but one of the last two hangs between confusing people.
(Is a cleve a huge smallblock or a small BB? who can know...)
 And I have almost gotten into fight over Pontiac motors. I don't care
what they say, Just because they only have 1 size does NOT mean pontiac
only has smallblocks. If anything they only have BB 's  :>
 Same for olds etc etc... There has to be a better way of defining these
motors.
