I recently towed a 28 ft 5th wheel trailer from Okla to Mexico and back with a 78 F250 with a 460 engine. Having never owned a 460 powered Ford, I was most impressed. On some long inclines, however, I could have used just a bit more power. I am leaning toward keeping this old truck versus buying a powerstroke, dodge cummings or other diesel, but got to find a way to get a little more power. What is the best and most cost effective way to do so? Headers? Larger carb? Heads with larger ports? RV cam? I've worked on cars and trucks for years, but have never towed heavy loads long distances. OK, you 460 experts out there, how about some suggestions.
Thanks, Mark.
