What was the gear ratio in your old truck and what is it in your new one?

Your pic looks just like mine. Did you put the blower on yourself? I was thinking in 94 they come blown. Mine is a 93 model, build #508. I get 12.7 if I keep my foot out of it. I say low miles for a 93, 124650.

He said both were FX4's, so most likely the same gear ratio. 3.55ls? Supercrew has 3.73ls.
