I was wondering if there is any advantage putting a 20r head on a 22r motor. I need to find a way to get a little more low end torque. My old truck was had a 20r in it and my new one has a 22r in it and they are pretty much the same truck besides the motor. The new one just feels gutless compared to the old one. I have the same size tires but the gears in the 20r were 5.33 and the gears in the 22r are 4.88s. My old truck had so much more power in the low end that at 1500rpm's it would still keep pulling. Now with the 22r if im not over 3000rpm's the motor is bogging. I had dual transfer cases in both trucks and i have simular problems when im on the streets or off. I have to reem the piss out of the 22r to get up the same hills that I putted up in the 20r. I have a header im about to put on the 22r. Any other ideas?
