So Im going to ditch the Avy for a new to me truck and I really want a 6.2, that being said, the nearest car dealership is 20 min away, the second closet is about 45 min. Im wondering if there are any obviously distinguishable differences between the 4.8/5.3 and the 6.2 based mostly on a photo of the engine bay... I am open to both GMC's and Chvevys

 

idk if u can tell a difference never seen a 6.2 lol but u can tell what motor it is by the heads

 

Im going to look at most of the cars via autotrader, so I was hoping to get something obvious, so I didnt have to talk to very many salesmen that would say anything to get me to come down to the dealership.

 

a 6.2 truck will have the tailpipe out the back under the bumper, rather than turned out behind the wheel. you may see that in a picture.

 

Awesome, thats what I was looking for.

 

And to futher elaborate on that, here is a picture attached below.

 

hmmmm...... Gay Pontiac huh????? Lol been there time or two.

 

Easiest way is to check the VIN.
5.3L, VIN 0, 8th digit, opt LMG
5.3L, VIN J, 8th digit, opt LY5
5.3L, VIN 3, 8th digit, opt LC9
5.3L, VIN M,8th digit, opt LH6
6.0L (VIN Y, 8th digit, opt L76)
4.8L (VIN C, 8th digit, opt LY2)
4.3L (VIN X, 8th digit, opt LU3)
6.2L (VIN 8, 8th digit, opt L92)
