How is your top end speed? Did you loose any top end pull? Does it help any like in the 60-90mph range?

 

Haha, why would you ? You just loose top speed.

 

I don't think your top speed will change, at least not with the 4.6 you should get some good pull off the line and all around better powerband
I went with 4.56's and all i can say is WOW @ 75 mph 2250 rpm's then again i have a 5.4 and a few other mod's not in my Sig

 

3.73s
162mph

4.10s
178mph

Our trucks will never see that, but your top speed will change, everything elese "gets faster"

 

but how about in a rolling race like I said doing 50ish will I loose anything there or would I benefit

 

Benefit. Why stop at 4.10s? I think I'm going to go with 4.56s in a couple months here. I'm saving for the XCal2 at the same time to account for the gears and hopefully headers too.

 

Headers lota $$ for not to much in gains

 

Yeah I know. I plan to boost in the future, though, and the headers do help a lot when you boost. At least, that's what I'm told. Probably not worth it on your 4x4 though (remember DevilSun's ordeal.)

 

No headers for me but will supercharge @ 10psi middile of next year and true duall bassani Exhaust and a few other mod's in the work's ill post if they work out

My bad no highjacking im out

 

I do a lot of highway driving right now and I think 4.56's are a little steep for a 4 speed in this day of high gas prices, I just want more out of the hole rip, but I dont want to loose to much up top either. So I just want to know if the 4.10's would do it.

 

MPG went up with gear's +1 in the city and -1/2 on the highway

 

yeah but you got a 4x4 and a 5.4 I want to hear from some 4.6 4x2's, or would it be the same with my truck?

 

You gain top speed with going up in gears? I thought you gain low end performance in exchange for top end. Please explain.

 

These are apparently some new kind of "special" gears... you learn something new everyday.
