i just picked up a 96 silverado extended cab long bed 4x4 with the vortec 5.7 and a NV3500 5 speed trans.

its got a 6 inch pro comp lift on 35" mud terrains, but my downfall, the guy was still running the stock 3.73's

this truck is such a dog on the freeway. ive got to keep in at NO LESS than half throttle to keep it a steady 60-65MPH on a slightly windy day. they say higher gear ratio = better MPG, but i think in my case i need lower gearing to up the RPMs more into the power range so i dont have to keep my foot in it....

this sound right?

what do you guys think, 4.11's?? 4.56??

keep in mind this truck has a 5 speed manual trans.

 

I'm not sure how the nv3500 is geared but since you say 3.73's make it a dog, i'd go with 4.56's.

I'm pretty sure you have an 8.5 bolt so you could always compromise and do 4.30 gear. Motive makes some and I believe Yukon does too.

 

second opinions anyone??

 

5 speed tranny on 35's. I'd go with 4.56's

 

i dont know about 5 speeds but i like my 4.56's with my auto!

 

sounds good. im going more for better mpg. i mean just going from common sence... close to half throttle at fairly low speeds, for highway speeds that is is definately sucking the gas.... so 4.56's sounds like a plan.

thanks

btw. do you guys think a CAI is worth it for the sole purpose of gas savings? its also got a flowmaster 40.. which is definately going, sooner than later..
