07 makes a little more power
That is the only difference?
Here is my issue, I bought an 02, now when I go to fire it, it wont, tore it down, there is so much rust in the PS cylinders it wont allow it, so I am trying to get the JY to give me a new one, which they are screwing me around on it.
So I found an 07 with 9K miles. If it is a bolt up, then cool, PCM and intake/harness are all done prior.
Oh no, the 07 is a gen 4, knock sensors are on the side of block and it has a 58x reluctor wheel instead of the 02's 24x
if its a Gen IV no its not a direct swap like the 99-07 classic 4.8 (Gen III)
you have to buy a 58x to 24 converter 275.00
you have to move your knock sensors to the side of the block (drill retap)
you have to buy a 90mm dbc 4 bolt throttle body 200-500 depending the deal you find.
i put a Gen IV 5.3 in my 94 chevy an i found all this out after the motpr was bought an torn apart. i had to change DOD out so
i could put a cam.
LS7 lifters/Trays
ARP head bolts
Head gaskets
Hardened pushrods
Well, even if it is the same LR4 not the LY2
This is out of the old body style " classic" not the new body style. By google and GM it should be the same, since they are both LR4's
yeah ya gotta specify 07nbs or 07nnbs it helps, '02 and '07 classic are the same unless it comes out of a z71

Thanks guys, I appreciate it. I was kinda thinking they were the same, but it is always best to get a second, third or fourth opinion from Knowledgeable sources.
