My Tahoe is an 06. I plan on getting a short or long block and refreshing it to drop in. My budget is tight. Are there any differences between years I should keep in mind? I have a feeling I need a 2002 or later but I don't know why. Is that the case or does it not matter?

 

Look for a 02 up, pref a 05-07 classic..

 

can you tell a difference from the outside of the motor which year it came from? i got a 03 with a 6.0 swap that a dealership did in 09... so i dunno which dang year motor they used...

 

Thats what I thought. I found an 03 shortblock I'd probably need to go through and freshen up but I think I'll wait until I can find an 05 or later. Thanks.
