The 3.slow is a slow pig. Sucks down gas and really not too much power. If you have an automatic then god bless you. A little more info would give us a better idea. If you are running bigger tires then you might want to regear. Always a good option to swap in a 3.4 or a 4.3 chevy(but who wants to do that hahaha) Best of luck Cheers!!!
