Decided to forge my short block over the winter. I'm currently at a 125 shot, and would like to work my way up to a 200 starting with a 150. I understand from reading older posts, 150 is my limit for the factory internals and fuel system. I've looked around and seen a MSD booster, as well as an upgraded fuel pump. For those of you running big shots, what do you suggest I do about a fuel system upgrade for my '04 Hemi Ram for more spray?
