I'm finally getting my car done. I have my choice of ratios as I have one of each in my stcok pile. I'm building the car mild enough so my wife could drive it if she likes. I'm leaning toward the 3.55s so its a little quicker off the liune but I'd also like to drive at 65 mph for 40 miiles or so every once and a while. I've been out of the game since I was a teenager so I could use some knowledge on how these ratios differ. Thanks....
