"Cam swap will get you 10-15 hp. Fifty hp from a cam swap is a pipe dream"


Porky has a right to his opinion, but....... The only people that think like him are those that run mild cams and never exceed 4500 rpms. Thats fine for them.
Look at any magazine article where they take a stock rebuilt 383, 440 or even a 340 and look at the results. The biggest gains are almost always after they switch to a bigger cam. Pathetic results like a 10-15 HP gain from a cam swap would be a huge waste of time for the expense. You'd get 10 HP just by switching to 0w20 synthetic oil.
