Re: Is 2002 5.7 an LS engine?
I can't seem to find any info on an all aluminum LS being used in any truck or van, previous to the LM4/L33 5.3 in 2003, then again until 05 with the aluminum 5.3/6.0/6.2 options.
99-02 only returns the all iron 6L or the 5.3.
PM or post the vin, either the criteria it was decoded with was off, or the vin is misprinted or something.
