MGA engine dimensions

["Mark J. Bradakis" <mjb@Autox.Team.Net>]

So I've got a pile of MGA engine bits, I think.  1500, 1600, 1622, hard
to say.  Being a Triumph guy I have pretty limited MG references at hand.
So what I'm looking for are bore, stroke, main and rod bearing journal
diameters for MGA motors.  Any handy web sites with such information?
I'd hate to sell some of these bits on Ebay with improper identification.

Thanks,
mjb.
