Well I hope everyone had a great New Years Eve!

Anyhow, if someone gets a chance today could they please measure the center
to center length of an MGB connecting rod?

Center to center would be from the center of the small end to the center of
the big end.  Or, you can take the diameter of the small end (without the
bushing) plus the diameter of the big end (without bearing), and then the
length of the rod between the to ends.  (D1 * .5) + (D2 * .5) + L = Center
to Center Length.

And if anyone can do the same for a Twin Cam rod, I would be quite grateful!

I'm attempting to gain perspective into historic engine design principals,
and what information I have gathered on our British cars so far, shows that
they really didn't care all that much about things like rod length.  Yet the
Germans and Italians were arriving at "ideal" 1.75 rod/stroke ratios in the
1960s (or as far back as my data goes for the moment) for their engines.

Happy New Year,

Kai
