Hey guys im new to this fourm. I am looking at a 2004 GMC duramax ext cab. New wheels and tires. Injectors have been replaced. Mild built trans. 1 stage efi live stack on edge juice with attitude. He is asking 11,000. It has the LB7 motor in it. the truck has 255,000 miles. im just wondering if this would be a good buy.

 

with those miles and mods, on an lb7, id be a bit weary but even though the injectors have been replaced, plan on buying another set in case that lb7 wants to eat them like they normally do.

 

See if he replaced the head gaskets, my 03 lb7 has 138k miles and I replaced the injectors and head gaskets already, and I upgraded to the arp head studs which is a good idea
