Hi all, this is my first post from down under, I was wondering if any body could tell me the differance between an MD7A and an MD7B volvo motor, we dont see many of the B models but there are still quite a few A models around.I am led to belive that the B model will rev 600 rpm more than the A model, but looking at the spec's I can't see where the differance is . Is this a simple and inexpensive alteration to gain extra rpm and hp or should one leave well enough alone. Cheers Taunto.
