Searched here and could not get a good answer. I have a 3.36 gear with my 700r4 in my El Co right now. Peg leg and will be going to a Yukon Posi unit I bought. While there should I go with 3.55 or 3.73? I like the idea of running at 2200 at 70. But know that it will only be like 2450 at 70 with a 3.73. Actually less drone from the damn Flowmaster at 2400.
Had them in a Mustang GT with the same .70 last gear in the 4WR70 it had years ago and they were a great blend. In fact less throttle around town means better overall mpg. The Stang had a 3.08 gear and moaned driving it or just not seeming to not work right. Seems the same with the El Co. Just not crisp at lower speeds around town. Stangs Gears are 2.84, 1.54,1.00, .70. Where the 700r4 is 3.06, 1.62, 1.00, .70. Did not see any difference in MPG at 70mph either with the Mustang. Of course we are talking Fuel Injection and better Aero.
I think I am talking myself into them? Can anyone give me some experience with a similar combo? I have a 350, Vortec Heads, Comp 268HE Cam 1600- 5500 range, 10.1 C/R, Headers, 600 Holley and a Jegs high rise.
