It really depends on what you want to use the truck for as far as bombs go. I use mine almost exclusively for heavy towing at high altitude and anything more than 350 hp I can't seem to keep temps under control at least on my budget. Putting money into 'fuel in' is cheap, plan to spend more on getting cool air in and exhaust out, you'll be happier in the long run.
