Too cold to measure main and rod size.

Fifty years ago an old time racing guy told me that this was a good crank for a racing engine!

He said with a big smile: :

"The Beavertail crank cuts through the oil vapor easier and has less air resistance!!

Anything that reduces oil friction in the crankcase means more hp at the output flange. One of the big reasons for dry sump oiling.
Dry sump = 15 hp gain.
