Hi folks,Long time no post,I am looking for some ideas.I have a 1990 f150 e/c short box.302 aod trans.I mainly use this truck for hauling my boat and car trailer around.It only has 134000 Kilos on it.It runs and drives like a new truck,But!!! Not quite enough power at times when hauling the car trailer over the mountains.Here are some of the modds I was thinking of.Converting it to mass air with cold air intake,long tube headers with true duals free flowing exhaust,gt40 heads,373 gears in the back,shift kit in the tranny for towing,This is where I need some ideas,what is a good cam for this set up.I don't think an rv type cam is not quite enough for these modds.I think I need a little more cam than that.What are your thoughts? Thanks
