Hello everyone my name is Jon i live in arizona i own a 01 1500 2wd with the 4.8. I have been working on cars and trucks for the last 15 years ive owned a 79 custom delux (pos) lol, A 91 k1500 shortbed stepside with the 5.7 and the one i spent the most time and money on was a 96 eagle talon esi with a n/a 2.0 that i put way to much money into and still got beat by moms in mini vans lol and then to have someone pull out infront of me and total it, Its a touchy subject lol. but not to bore you with import stuff I decided to get another truck and now i have this bug crwaling up my ars to start messing with things so i have some questions? I just need the basics of whats what on these trucks .

(1) are the 4.8 and 5.3 both LS1 setup's with just a differant bore ? So external parts would be interchangeable between the two. Or is it like the tiny differances between the 350 and the 327.

(2) What about parts i have been looking at jegs and summit will the parts they have listed for the LS1 work or is it one of those its the same but differant things. I look for it under the model and not much comes up yet i look up the 4.8 and i get abunch of stuff . grr

(3) also ive noticed a rather rough idle is that common with these motors ? I've changed the plugs and wires fule filter with no results. Ive been told that the injectors have a tendancy to get carbon build up on the ones tward the front of the engine is that true ?


Well thats enough for now and i apoligize if thses should have been posted in a differant place . Thanks in advance
