Gear Ratio

[GregWeld]

Right! Sorry SWAIN!! Sheeeesh -- I have a bad habit of doing that! My bad!

Mario -- tire size is close enough for the purpose I was trying to demonstrate... a couple 10th of an inch diameter isn't going to change the basic tech session I was running there...

My point was really more about how critical - or really - about how much difference there is between all these seemingly 'simple' factors. Tire size - final drive ratio - desired cruise RPMs.

A buddy has a 454 bbc Imagine Injected 56 Chevy with 3:55's and a 700r4 -- My 56 runs a 427 sbc 700r4 with 3:73's... I can hear the difference and I like mine better... and I've ridden in both (DOH!) and my 3:73's seem to put a little more bounce into the step. Would I like something in the 4:10 range? NO WAY... Do I care about gas milage? NOPE! I do like to drive my stuff - but also want relatively snappy performance so life is a trade off. :>)
