Personally I liked my 3.42's. I cut 2.0-2.2 60's with them on a 29" street tire in my 5.3, mild cam and TT3000 verter. I ran 14.3-5 in 3000+ DA with that setup.
I later installed a 6.0 with a slighty bigger cam and ran 13.2-3's with 60's in the 1.95-2.1 range on 29" street tires and 3.42's.
Sounds like you plan to keep this truck as street friendly as possible. I'd keep the 3.42's if you are running nothing larger than a 30" tire around town. Otherwise the 1-2/10's you gain from gears isn't worth the sacrifice in daily driveability, mpg etc. Especially with that blower you will like the 3.42's. People can argue with me all day, but that's my tried and trued opinion.

As some know, I can multi-quote w/. the best of em. So since I couldn't make it on PT, I see quite a few replies. Here ya go.
I manually shifted for runs 2 & 3.
I wanna say I "X"ed traps in 3rd. As I said, prepartion was nil cause of work. Next Wed. or soonest Wed. thereafter, I'm goin again. This w/e, fuel & shift limits will be raised. I wanted to toy w/. how it sits, so on way home today, no traffic, put in 1st to see what happens. Tried to run it to 6K, but it sputtered ~5800 in 1st (hit limiter, so I think 1st is lower limit than other point(s). I tried again just ahead. Target 5800 on 1-2, I hit it almost perfect, shifted & chirped em. That was beautiful. Startin to see what I'm missin.
1 of these days, 1 of these days. What stall / converter do u have?
I too was wondering when is rental & how much? Just call me, or for once, pick up phone, Joe!!! 
He's pretty sharp. I've learned some stuff from the times I've been there, including that last dyno session.
02slow4.8, I think u have my #, if not, PM me. If Joe doesn't confirm date & $ for rental, I'll be goin again this Wed. or following Wed. I've got some ideas & things to get.
My tonneau installer said w/. certainty it's 110#. I asked, & he seemed confident since they do quite a bit it sounds & he wanted to verify what one weighs, tho it wasn't mine he weighed, he said it was a RCSB Chevy lid. Dyno / tuner Sean, told me the aero u gain, more than offsets, weight penalty. I'm not so sure. Not at least til I weigh to verify myself.
Ya, I don't really count the 1st run, but rushing screws up thinkin & therefore, consistency.
I'll find out soon how much is left. I plan on another Wed. T-n-T or this rental.
Pre cam MPH: 89.08, .43, .65, .68, & only one over 90 (90.17).
Pre cam ETs were 15.132, 15.1322, 15.085, 15.0088 & 15.142. Only changes were no spare nor jack on some runs. Temps were ~67° falling later to 61°, & last run was ~57°. DA ranged 1061, 992, 733, 648, & 422.
So if u want corrected: 14.969, 14.982, 14.987, 14.927 & 15.104.
Another day, I should mention w/. stock stall & trans, (no lid, no jack, no spare), my best ever was 14.8.
He tuned so I could run 87 or 91, it automatically compensates. How IDK... detects it in gas?
Corey, I normally did run 87; & started using 91 more, almost exclusively @ dyno / track. That was prior to cam. Since cam, IIRC, I haven't used any 87, just 91 & this time 93. Whole reason we changed plugs cause I was pickin up lil knock at dyno.
i am still rockin the 3.42s but they are hurting me in the 60ft area..2.0 is the best
up the shift points my 1-2 is at 6300 and 2-3 is at 6100
I maybe be off 100rpm on my shift points but that will get you close
3.42s run the quarter in 2nd gear or does it shift into 3rd and cross the traps?
mine goes in 3rd and crosses the traps within 100ft i bet so it kinda falls off then crosses

I pulled out my last slip i ran and compared it to your last one, its ridiculous how close it would be between us..
Now with that said i dont have headers, cam, efans, 1/2 a stall
. You have a lot there left, keep at it and im sure you will get it where you want it before the huffer goes on with the loss of some weight and shift point change..

I did not remember Sean tuned your truck, I want to meet him, he has some interesting experence/ideas about LSx stuff

Unless the bed cover is heavy don't take it off. I would say 50 lbs is better then the extra drag of having the gate and cover off.
It isn't dialed in I don't think because even't a baby cam should net you more then .2-.3 & if you go from your first time you only gained 1-2 tenths. Maybe it was just the rushed pace of getting there late but somewhere there has to be at least .2-.3 for you to pick up. Good luck and hopefully you get faster next time out.
p.s. What were you mph before the cam? That will help decide if you are making more power now.
...Wasting your money on high octane fuel when you don't need to is foolish and if anything will hurt performance a tiny bit because it takes longer to burn. I don't know if it is at all noticable but unless tuned for something above regular never waste your time with anything higher.

See prev. comment to custm2500 on lid weight. I think I can par that down next I go (soon). I wasn't sure how nice cam would be, so I had extra fuel in case, so I don't get caught out in the sticks outta gas & no one to help me. The weekend is different, cause if that happened, I've options.
I run 100 proof from the pump, 5 gallons and just over a 1/4 tank at the track
Get those 4.10's. Yes, I run 3.73 and 4.10's would reduce my chance of ever putting it to the ground but my setup is slightly more radical.
Lose ALL the extra weight. The amount of 'drag' is nothing compared to the amount of energy required to get that extra weight moving.
Tuning.

Or how bout NA in snow or boosted in snow?!?
Tom, you're shifting way too soon. Try adjusting your shift points to 5800, then 6000, then 6200, see what works best. 3.42's with your tall tires are hurting your 60 ft times, you already know that. Drag radials would really benefit you.
Still, that's a decent improvement for only a cam swap. Congrats!! There's a little more in it for sure.

I don't think I'll go as high as 6350. But 6200 maybe. I gotta see. 6300...

I might would do 6300. It just worries me. This may be wrong, but fear of valves floating I guess. Give me some better details: XR265 high lift, mildly stalled, bolt ons, N2O outlet plate 1XX pills...? Like cam specs, stall, shot size? And what kinda 1/4 do ya run?
