There are other things to consider here. First of all, the iron block LSx motors are truck engines. This means that swapping them into a car is illegal here in California (and possibly other states as well). There are no such problems with the LT motors. Also, LT motors have the advantage of simple, OBDI electronics. And as for the aftermarket, I don't think it could be called bad for ANY of the GM V8s.
