Commando Con Rod Lengths

Can somebody please tell me the length of a standard commando conrod centre to centre journal to little end, and also the centre to centre distances of Jim Schmidt's longer conrods ? I would like to do a calculation which involves that knowledge.

I think you could find here above....hope this help.

Thanks for that - got it. I want to try and calculate the shape of the advance curve in a commando which gives a constant starting point of the combustion event in relation to the revs. I don't have the software to produce it these days, so I'll need to find a copy of Basic A somewhere.
Jim's long rods are 6.400 inch, and the standard ones are 0.525 inch shorter.
