I know there is a trade off and with pros and cons to everything.
Sometimes it can be a bit confusing.
I know with the 456's I can push larger tires and change fuel economy, but will it help me make It up those long up hill stretches of highway here on the left coast without shifting down to 3rd gear?
Will my fuel economy encrease or decrease with the 456's installed?
This last trip from San Clemente, CA to Pismo Beach, CA approx 250 miles with the 60 loaded down, we achieved 16.9 Mpg.
Rebuilt 2f, 32/36 weber., heavy duty wires, excellent plugs gapped to 40,000th, timing is around 5 degress/retarded. Next is a MS box.
Back to the gears.
Can someone please explain what switching to 456 will do? The pros and the cons.
Thank you in advance.
