Rollers for a 5.4 V8
I have a 98 Ford Explorer with the 5.4 Litre engine that does just fine pulling my 20' Enclosed trailer until I hit some large hills. The damn thing slows to about 60 mph while reving to about 4000 RPM (not in overdrive). On my former engine I went to 1.7:1 Ratio Roller Rockers and gained a noticable gain in power on a 302 engine.
I know there are other mods I can make on this engine but to change out the rollers would be very quick and simple and fairly inexpensive. Any pro's or con's?
