Thanks guys great input. It wouldnt be a play truck more of a shift to 4x4 when i gotta pull someone out or go through the snow. i know tires also play a big role in how well the motor performs. currently it has some heavy duty 20 inch rims and duals on the back. ive just got a set of 16.5s that im gonna put some 37.5 humvee tires on it. is this gonna bog it down to much even in when only in 2wd. sorry about all the questions but im not very good with motors
pic below is how the truck is currently sitting and the motor that needs to be cleaned
