4.10 gear question
Shouldn't I be able to spin the tires without using the clutch with 4.10 gears in a 96 LT4?
I'm talking about traction control off, at about 3K rpm, in 1st gear, on dry pavement, with all season tires, then nailing it without dumping the clutch.

I would say it depends a great deal on the tires.....and looks like you are stock......but I would say probably not on good pavement and warm temperatures with good tires...
..on the other hand, pretty easy to spin with some moderate revs and dumping the clutch
...and yes I ran 4.10's on my near stock LT4 for several years before the mods

Yes, I had the gears put in so I know they are there.
Maybe it's just suspension geometry or weight transfer differences, but when I do the same thing on my 95 Camaro LT1 6 speed with 3.73 gears, it will roast the tires. And it feels faster.
I'm going to take it to the dragstrip. That will prove or disprove my perception. I'm thinking if I'm not at least in the high 13's, then something is wrong.

I have driven plent of LT1's that from a roll in first at 20MPH with good tires that will not spin the tires. Some tires work really well and the car will not spin but it will accelerate very well which is what you are actually after in the long run.

Good luck...let us know how it does

Best pass tonight was 13.85. That was with very little wheelspin and with very good shifts. Probably the best I could do.
It looks like the web consensus is that I should be around 13.3.
A little disappointing, but not really horrible.

Density altitude and your original question in most cases no.
Its stock. 13.8 isnt bad for your first time out especially in this heat
You gotta take a few variables into consideration...not great air out here so no way a stock Lt4 is going to do much better than that. A heads/cam/header LT4 on drag radials will just crack 12s, other parts of the nation will be much quicker so dont be too quick to judge your car a turd.

Your MPH is what indicates the HP you are making. You should be at 105-107mph if otherwise stock. FWIW, when my LT4 was stock other than 4.10s I ran a 13.009 at 106mph. Stock everything it ran 13.38 at 105. To answer your original question mine would roast the tires if I floored it from 15mph in 1st gear with just the 4.10s. Lastly, your rev limiter is 6300rpms. You should be shifting as close as possible to that at the dragstrip for best times.

Wow the elusive 12's!!!! I only had my car to the track once when near stock and that was with the 4.10's.....my best as I recall was a 13.3 and 2.0xx 60 ft....another forum member that day with stock gears and near stock LT4, and a lot better driving went like 13.1's
Yes
you need to be shifting right at the 6300 redline, I forget right now, but the actual rev limiter is just above that, 6400 I think??Your MPH was ??? BTW 13.8 in bad air would be pretty good

Temperature was right around 80 that day, not too humid (but how much role does humidity really play?).
I shifted at or near redline, never hit the rev limiter though.
My final MPH was 105.
Still, the car just doesn't seem to be pulling hard enough. It's almost like when then engine gets a load put on it, it retards the timing or something. In between shifts, it seems to pull really hard right after shifting, like it will jerk you back pretty good when you first hit second after shifing from first, then kind of die out. Same with 2-3 and 3-4. Of course this is with the traction control off.
Got no SES lights or anything to help. Thanks for all the input, appreciate any more thoughts any of you have.

Tapping the limiter won't hurt anything, you might creep up on it in 1st some day on a clear road, just to see if the tach is on.
That MPH seems pretty good though, so maybe you just need to shift quicker, etc. A 1.99 60' is good for street tires (in my opinion anyway).
