Difference between 01 and 02 6.0 motor?

[SteveSierra]

I hope someone can answer my question.  Maybe much hasn't changed and I shouldn't be concerned but,

I have an 02 that was built in early July 01 and has EGR.  I heard later in 01, the 02's were built with different programming, maybe cam, different maf, etc.

My question is, when I start modding the motor, do I get parts for an 01 motor or an 02???  I hate it when GM does this crap!  They did it with the f-bodies in 01 too!!!!!!

Thanks

If you plan on going into the motor, when you order a cam, you'll just have to specify that you have an EGR system.  You can get a cam with the same lift and duration, but may have to go with one with a little tighter lober separation since you have an EGR system.  Otherwise, when upgrading from a stock cam, since you're going bigger, there isn't an issue.  I would suggest that you do get a steel billet cam.  If the 6.0L is like the LS1, the stock cam is hollow.

 

FYI, not that much changed between the '00 & '01 F-bodies that constituted any major difference in aftermarket parts.  The major thing was the LS6 intake which can easily be retrofitted onto prior '01 cars.

Thanks man

One of the things I heard that changed was the size of the MAF.  If so, then maybe the 02 intake kits wouldn't work on my engine.  I would need to order an 01 intake kit, I guess?

Unless the MAF housing diameter didn't change.

To my knowledge the 6 litres are the same 01 and 02.. A friend of mine just got a 2002 6 litre (feb.2002) and I have been all over it..It has the EGR and everything.. I do know the 01 and 02 5.3s are different.. The 02`s have the EGR deleted..

 

BTW,The maf is also the same diameter..99-2002 is 80mm.. No change yet..
