I thought it was funny, I'm doing 60mph in 4th @ 2200 rpm put it in 5th dropped to 1200 rpm... I think I have room for better gears...lol...
yeah, I am planning on running 3.50 gears in mine. In my 55 I have 3.89's and that is too low for me, I need to shift before I get thru the intersection.
Running too low rpm's could hurt gas mileage because the carburetor will be running on the idle circuit which runs richer than the main circuit.
I am going with the 3.73 but I have an 8.8 been flirting with the idea of 4.11 since I will be running 18s
Im running 3.55's with a T-5 on mine and I noticed that my MPG slightly boosted after changing to 3.55's from 2.79s. This is what was probably happening to me.
I will decide between 3.25 and 3.55 gears... I think one of these will wake up the car, I want a quick driver that still has good highway maners... My t5 has a 2.95 first gear...
