This may be a stupid question, but I just got my 84 S10 Pickup 4x4, and I was wondering what size tires would be too big for the 2.8 to do well fourwheelin. I don't want to put too big of tires on it that it has trouble since it doesn't have a ton of torque. It has a 2 inch body lift on it, and can fit 31x10.50 on it if I wanted to. Would that do alright? If I was to put another 2 inch suspension lift on it with possibly 33 inch tires, would that be overkill on the engine? Eventually I would like to do the 3.4L swap, and I know it could handle it, but I don't want to overstress my 2.8L while I have it. Thanks for your help.
