Is the 2005 5.3 still dubed a GM slapper?
Looking into trading in my 2002 Sierra Z71 for a 2005.I want to know if anybody knows if the 05's are slappers like the former 5.3's.My 02 5.3 is a good one at 103,000 k's,still running strong and healthy.I guess this is a good one as no sound comes out of it cold or hot.

Thanks guys.I guess I will have to make up my mind.My 02 purrs like a kitten,not one noise out of it.I'm interested in the 05 because of better HP.Dealership told me 330 verses 295 for the 02.Anybody with the 05,how is the gas milage?

310hp w the L33, 295hp w/ LM7, TQ is the same for both motors as far as I have heard. I am avg'n 17.5 city driving and 20.5 highway. I have 500 miles on it now. I really wish I had found one with 4.10's, but the gas milage is good with the 3.42s. I hope this helps
