I traded a 2004 Silverado Z71 in for a 2007 Silverado Classic LT. My 04 had the 295hp 5.3L Vortec and a "T" as the 8th number in the VIN(the numeral that will tell you what motor you have). I looked at the VIN of my new truck and the 8th numeral is "Z". I think that "Z" is the code for the High Output(310hp and aluminum block) 5.3L Vortec. I looked at the sticker and it only says "5.3L Flex-Fuel Vortec V-8". The guys at the dealer weren't sure about whether or not I had the HO Vortec, but they told me that I should research what an 8th digit of Z means. They told me for sure that I can run on Gas, E85, or any mix of the two..... that's kinda cool. What the hell does "Z" mean for the 07's? Do I have 295hp or 310? Thanks!
