I'd take on a B any day! But don't ask me to lift the hood. My 1500 is now 1800. /ubbthreads/images/graemlins/laugh.gif A 1600 or 1622 would be competition for the B, but the early 1500 is a bit lacking in the power department.
I'll tell ya one thing though. An MGA with the same CC as an MGB is one fast car. On our local drives I drop just about everyone in all makes and models going up the canyons.
And I also agree that the MGB is a sports car, it's just a more modern one, designed with comfort and modern anemities in mind, as opposed to the purpose-built sports cars of the 30's and 40's. I wouldn't sell my B for any reasonable amount of money.
