Big O Posted January 2, 2007 Report Share Posted January 2, 2007 Hey guys. My coworker is looking to buy a new silverado and has some questions about the differences in the new motors. He was saying there is 4 different levels of the 5.3 and was asking me the difference. Is there a spec somewhere that I can give him to use as a tool to evaluate the difference? Thanks in advance.

Big O Posted January 2, 2007 Author Report Share Posted January 2, 2007 when the wifes TBSS was in the shop they gave us a Tahoe to drive and it had DOD, and I hope it wasn't a 6.2 because it was pretty gutless Quote Link to comment Share on other sites More sharing options...
