Thanks for the tip! I'll do that when I'm on the lot.
What I'm doing is shopping over the net, checking inventory on the (many!) Chevy dealers in SoCal. The web sites describe the car, let you see a "sticker", and give you the VIN. I don't know if I can trust their "sticker" or written description ( they often call an interior Custom Leather when it's really the Sport Leather ) but I would trust the VIN as being accurate for a particular car, at least as it relates to the basic drivetrain. That's why I wanted to be able to decode it
What I'm trying to do is find a 4.1 rear end, and don't want to travel 75 miles to a dealer only to find the car's description was in error. Am I wrong in thinking the rear end ratio would be coded in the VIN?
Wow! I did WEB searches, and found VIN decoders for lots of classic cars, but nothing for current vehicles. Hence my post here. That was exactly what I was looking for! Thanks a million!
Of course, the bad news is (and I have to admit I'm a little surprised) the engine is specified but not the rear end gears!
Thanks to perusing this list, I know a 4.1 rear end will result in 2200 rpm @ 70mph, while a 3.73 will yield 2000 (roughly). I'll just have to verify that I got what I wanted on my first drive after break-in when I can go that fast
Thanks, gandolphxx, for taking the time to help me out. I have gotten lots of great info from your other posts and look forward to "mod-fever"
Anyone have a VIN decoder for the current GM vehicles? I want to check an Avalanche VIN out, but the link given in this thread does not work. I what to confirm the build ate form the VIN any ideas??
No, nothing in the VIN will specify any date. It can be reasonably guessed with some other data collection of VIN numbers and the associated production dates, coming close to an average daily production figure, etc.
