So, yeah i dug this up from the dead, what were you guys stock 4.8 times - bone stock? I ran mine (i have some added weight) and ran some "go home and cry in a corner" slow times, just seeing how a very bone stock 4.8 with 3.23 rcsb is supposed to run.

Probably not going to run very good with those tall gears. I ran my rcsb 5.3 all stock with CAI and cat back exhaust with factory 3.42 gears and G80. I think my time was right at 10 seconds if not a little under in the 1/8th. So with a smaller motor and taller gears you will be a little off that time I would imagine.
What were your times? Im guessing they should be around mid 15's with a rcsb.

I sat down today and came up with a list of things that i can remove from the truck, whether stock items, stereo equip, etc, and i have almost 400 lbs of weight worth of just removable stuff. 100 lbs of that extra weight is in the wheels. i'm thinking with the stock wheels and pull that extra weight, i should get at least a 16.5. This is my first go around with a "heavier" vehicle. In my integra just having a 150 lb tool bag in the trunk caused me to run .8 slower, so not really sure how linear the weight removal will be in my 1/4 time with a stock truck.

yea its horrible all the way around, embarrasing horrible. Mods start as soon as Christmas is over with. 60' was 2.6, i'm trying to get an idea of what times should be with a rwd v8. My integra was running a 15.1 @97 with stock internals, just bolt ons, those cars have zip for tq and a lot of high rpm hp (8200 factory redline). I'm guessing high 90's with a truck would be mid 13's?

Yeah thats a terrible 60. Mine was like 2.2 and I was spinning a little bit to boot. My first mod would be 3.73's or 4.10's I think. This will help your 60, your trap speed, and your overall et. Search around here for moded times. I know people are running mid 14's with bolt on 4.8s. Or you could just turbo it, that seems to be the real popular thing to do with the 4.8's these days. Lots of people making real good power with them.

Everyones time i see posting for a bolt on 4.8 are high 13's or 14's on average, and claims of mid 15's stock, just curious how they got these numbers because it looks like they ended up with Wednesday cars and i ended up with the Friday car, haha, while working on it they said its F*** this S*** o'clock and went home.

More than likely they have lower gearing from the factory than you and are probably running a smaller/ligher wheel/tire combo. Judging by your pic it looks like you have 20's at least so that is a lot heavier than the lighter mag wheels that come stock and the extra height means your high gears seem even higher. Most guys with 20's run about a 31" tall tire, for comparrison I run a 29" tall tire on my stock mag wheels and I bet my wheels are about half the weight of most 20's. So lighter rotating mass/shorter tire/lower gear = quicker in the quarter.

My ext cab 4.8 with 3.42s went 16.3 at full street weight plus my all my crap for work in it, spare tire, tailgate, steel wheels. With a k&N, longtubes, and wheatley tune, lighter aluminum wheels and some weight reduction it was running consistent mid 14s. Best of 14.4 but mostly 14.5s and 14.6s. With the same mods on tahoe 20s(heavy)wheels, it went 15.1 at street weight with the 3.42s. I put in 3.73s and a locker and that helped out alot, but never went back to the track. The 4.8s love low gears, that along with a higher stall will get it moving.
