I've heard the 7A exhaust cam may be an upgrade when used in the 3B and I'm=
curious where this notion came from. Has anybody dyno tested using the di=
fferent cams? Does anybody know that the lobes are cut to produce better p=
ower in the 3B? If so why wouldn't Audi have used it? Did it sacrifice lo=
w end for high end? My recollection is the 7A motor is pretty gutless down=
low - here in Denver around 5200 ft at least. I'm in the process of putti=
ng a 3B together for installation into my '84 urq and will have the opportu=
nity to use the 7A cam if I choose. All input appreciated.
