Re: Does Changing Firing Order make more Power?
The top sportsman engine builder in the country was asked the reasons he installs 4/7 swaps in his customer's engines.
"Because they expect it" was his answer. It may pick up a couple of foot lbs of torque, but not much more than that. It may run a bit smoother, but bearings look the same at tear-down with either cam.
