I would definately prefer a 390 because I need to be able to pull heavy trailers with this truck. 215 sounds good as for HP if that is accurate. From what I here the HP on the 302 is right at 130HP so the additional HP will help. Torque is more important for towing though. The 360 runs smooth and strong without smoking. Selling the 302 when I can (does not smoke and runs well) but just not the strong engine I need for my towing needs.
