This truck was used as a farm truck for quite a while. It ran well when i bought, but around a year ago it decided to go crazy! SO... entire new brake and fuel system later, the engine sounds terrible. I'm pretty good with electrical stuff, but engines are not my forte. I'm considering a swap because my neighbor has a small block chevy 350. Any thoughts on the matter? I love the way these trucks are engineered, but the swap is instantly more power...
