Get some 4.10's and a 3600.
EDIT - on a 4.8 get 4.56's and a 4000.
It will rob low end for sure. .... how much and whether its too much would be debatable.
which i already have a 3000 circle d stall with 373s in the rear which price wise he told around 1500 for the complete install and cam and all. i was thinking more of a 224/224 112lsa how would that cam do and looking for a good lope at idle
If you want a raunchy idle and would still like to maintain most of your low-end power, and 3000/373 setup, take a look at GM's LS1 Hot Cam (218/227 .525/.525 112).
It has a fairly early intake valve closing event, so you'll get some decent low-end power with your 4.8.
Here's an idle clip:

this topic is over and over again. ppl dont realize a 4.8 is a tinyass motor. the gears and stall you run typically for a larger motor dont work so well with the 293. the 4.8 is modernday 302 if you think of it. short stroke so it can rev. you can get away with a decent cam in the 4.8 but you need the supporting mods. you need to spin the motor 7k-7500. doing so you need gears to help you thru the rpm range and large stalls.
a 3k stall is for a stock motor honestly. 373s unless your running 26" tires arent enough.
or you could settle for a small cam in the 4.8. even then your stall and gears are to small
so i ran a 15 flat with my mods now how much of a difference would 456 gears make i dont mind it reving higher on the higher i dont go over 70 which my tires are 30.5 height im just trying to get the most out of my 4.8 thanks for ur advice
depends on what hte ttruck is trapping now with rpms. you could expect 3/10s but that is a general estimate
quik its trapping out 89 to 91 which its
60 2.143
330 6.220
1/8 9.654
mph 72.04
1000 12.567
1/4 15.051
mph 89.63
if that helps
rpm wise going thru traps. installation of gears help or hurt a motor. ideally you want to be at peak power crossing traps. so you gear and tire for those rpmsQuote:

ok besides reving around 2400 rpms doing 65-70 mph how else would 4.56 gears affect me driving normal and full throttle i have 3.73s now will it shorten 1-2 mph shift and will it make it louder or quieter will light throttle thanks mike
