I hate my slow *** stock truck...I want some pep and possibly some resale value. I found a LS1 bottom end (short block ish, has everything but the heads)that needs the crank turned and a bearing kit plus honed for 400 bucks. Will my heads and exc bolt on? Should i swap my cam? Is any of what i'm saying possible lol? I can do some rewiring, im not a complete idiot, i just put a geo motor in a 1st gen toyo mr2 (buddy was broke and had a blown motor) and it required some rewiring, but it was the exact same motor. This is different. maybe some one can give me a list of things i will need or even if this is possible or am i just talking out of my as$. So, first oil pan? will 4.8 headers bolt to a ls1? intake? heads? ls1 car cam to my truck? or should i just go buy some nitrus?

You have a great deal of reading to do. but yes. all LSX blocks are the same.
Might as well use an LS6 cam, it'll be a good all around cam. use everything else from your truck.

awesome. pan from 4.8 headers from 4.8 and heads from 4.8... how about intake? LS1 or 4.8(motor is off of trans am isnt the intake a ls6 intake)? with the bigger cam wont i need bigger valve springs and such? and my truck is a drive by wire bs, how will this affect the swap?

use the truck intake. which is why i said "Use everything else from your truck"

You can use the stock ls1 cam if you want, but if your swapping the engine you might as well upgrade to an ls6 cam/springs. or bigger if you wanted.

ok, sorry, i was just getting excited. I guess my bike is going on craigslist tomorrow (unless its a miracle and my income tax check comes in the mail when i need it to) so for prolly 1200ish total with me dropping it in.(ls1=400, cams=500, and machine shop=?)
around 350ish horse? if i cant find a ls6 cam how much difference is a lq4/lq9 cam? what year ls6 cam? the 01' or the 02'/z06 cam? the 02's cam needs alot to achieve its potential!

the 5.3/4.8 block is the same.

you will want to have it machined to the 5.7 specs, and then if you want, use a factory 5.7 rotating assy if you are just wanting a 5.7.

or, like myself, I am going to go with a forged 347 out of my 5.3, unless I can score a 5.7 block CHEAP.

I have a complete 6.0 sitting here I want to sell, cause ive thought about the 408 stroker, but I would like to see how bad I can make this 5.3...lol

Im still untuned for all my stuff, and look like a diesel blowing black smoke, and the soot around my tip...lol

I would honestly stick with your 5.3, put heads/cam, longtubes, CAI, and a 125 shot on it.
lower gears and a nice stall will bring out more in it too.
You will be smiling after that.

If not, there is always a maggie or turbo.
