[Roadsters] What year is my car?

[Paul]

  Most of the old time racers did use the 3 main blocks.  But here in Ohio,
there just aren't many flat dash roadsters willing to sacrifice their
engines.

If I recall correctly, BSR always used the 3 main block because it produced 
less friction a therefore a bit more power. Since the crank was short enough

and stiff enough, there was really no extra whip with only 3 bearings.
