    There is/was an equation where you could determine the ideal V angle of an engine, but I've forgotten it and can't seem to find it. Any help?

    I think it assumed that opposite banks of cylinders shared the same crank pin.

    I think I've kind of figured it out. I believe the angle between the V needs to be a multiple of 720/#of cylinders. (unless you have something like an odd fire V6 which instead of 60/120 degrees between the V you have 90 and it fires at 90 between each bank and 150 degrees between the three 90s.)

    The only engine that I know of that shares the same crank pin/journal is the Harley Davidson V-Twin. It is that configuration that gives it that distinctive "Harley" sound........

    Pretty much every domestic 90 degree V8 that I can think of has opposite cylinders sharing crank pins. IE; in a small block chevy, there are 5 main journals and 4 connecting rod journals.

    I don't know the equation, but here's some food for thought;
    At one time Cadillac made either a V12 or V16 with 135 degree cylinder angles. I wonder what THAT crankshaft looked like????

    are you thinking of what the best angle for a given number of cylinders in a v configuration, as to why the 60 degree V6 is 60 degrees?
