Going bigger displacement, need help! I was thinking either nitrous or a rebuild and big displacement would be the next move for me, and I am pretty sure I have decided to go bigger. 
Now, I have a 99 5.3L. I would like to be able to bore it, because the stroker kits for this truck are rediculously high (well, as compared to an old SBC).
I've been told I can have the block resleeved and what not and the I can bore it, but I don't know how all of that works. Can some one please explain the process to me as far as "max boring" a Gen 3 motor?
What am I looking at in terms of cost?

i really wouldnt reccommend boring a 5.3 block because it can only be bored to the equivalent of a 5.7 liter block.so you may as well get a 5.7 liter block for cheap(there everywhere) and build an entirely separate motor.this way you have no down time because when your done all you have to do is swap in the new motor and you'd save yourself a bunch of money.if you hade the cash you could bore the ls1 block to go bigger if you needed to.a common thing to do is take a 5.7 liter block and swap out the crank to a 4" so you make a 382.hope this helps good luck
your block is iron, you dont have sleeves. the 5.3 can be bored out to 3.900 and you'll end up w/ a 346.
honestly i'd either look for a 6.0 block and build off that or throw on a magnacharger on your 5.3

Thanks for the info!
I am just curious as to for just how "cheap" I can get this LS1 block? Cheap as in 350 bucks, or cheap as in about 800? If I couldn't bore the 5.3L, I'ld want a 6L. (I think) The 6L is an iron block, while the 5.7 is aluminum. How much weight savings would there be?
Does the extra revving capabilities and lighter weight provide more advantages then the 20 or so extra cubes?
And you are right, I could use these 5.3L heads on top of that LS1 block....

~80lbs difference. used ls1 blocks go for 300 - 400 bucks, i've got my 98 block for sale.
"Does the extra revving capabilities and lighter weight provide more advantages then the 20 or so extra cubes?"
of which setup?

I can't afford the radix, so I'll have to let that one go.
JRP:
Do you not see an advantage to the lighter LS1 block and higher rev capabilities?
Also.... what are the differences (in terms of material) of the reciprocating components of the 5.3, 5.7, and 6.0? Are the rods, pistons, and crank iron too, or just the block?

Just curious ---- how much are you selling that LS1 block for? How many miles, etc?
What is truck freight on something like that run? What do those assembled blocks weigh (the LS1) -- 300 pounds?
I don't want it now, but I will be doing something when I get back from basic.

Not bad, how much did you pay for the block -- so that I may gauge the market.
---------------------------------------------------------------------
Another question:
If I were to go with an LS1 shortblock, could I just slap on my LM7 heads..... I've heard they flow the same as an LS1 head, but just have smaller valves. So, could I just get whatever work I needed done on the heads to accomodate bigger valves, and just benefit from the raised compression? Is that all there is to it?

usually its worth your while to get a block that has something wrong with it since your going to do a buildup anyways you get the block cheaper and just junk or sell the messed up stuff.to be honest i think im getting a awesome deal getting my block fixed.
