I bought my truck used so i didnt have much choice on engine size. I was wondering if anyone has any ideas on how to up horsepower.i'm not looking for anything extreme just to add some. (You can never have too much power) Thanks

dual exhaust is always a good way to get some good power for not to bad of a price. airaid is another thing that would be good too and would be cheaper than exhaust...some people tell me that airaid is like dual exhaust all over again

What about a chip? any ideas?

i think the deal with the power chips are that you need to make other adjustment first do make the chip work to its potential.
a complete air and exhaust system.
I heard those throttle body spacers are good.
180 thermostat, better plugs and wire setup.
all the outer upgrade motor stuff.

Low restriction air intake and exhaust. Duals aren't necessary, just go with a true 3" mandrel bent system. You can also port your MAF, that will help out too and it's free. Go to http://www.LS1.com for more info. Yes, that's mainly an F-Body site, but the 4.8 is a version of the 5.7 used in Vettes and F-Bodies. All the same tricks work.

Also check out SLP, they have a line of parts for LS1 engines.

You can also make better use of the power you have with a transmission shift kit and torque converter with a slightly higher stall speed. Yank and Precision Industries are two good ones I remember from my F-Body days. I had a 98 Firebird Formula with the 5.7 LS1.

Same thing with gears. What gears do you have? You might want to install a set of 4.10's, especially if you have larger than stock tires. The LS1 engines like to rev, so those gears might put it more in the powerband.
