I need some help from the motor heads on this board. I have found a 90' something, single cab 2 wheel drive truck to pull my trailer. I was talking to the dealer and he said the 300 4.9L is better than the 302 motor. What do you all think? He said there are a lot of problems with that motor. We are looking for a truck in the early 90's any brand would be fine. We want to stay in the 1/2 ton range also. I pull two ZTR's on a 16 ft tandem axel trailer. Just want to make sure I have a big enough motor to pull without struggling. Thanks. kooba.
