Wish my 4.3 was this clean...
 

A family friend just bought a brand new Silverado with the 4.3 in it. I still find it hard to believe that at heart, they are essentially the same haha...

Lol, I wish my engine was as clean as either one of those.

My was that clean...once. The day I bought it new off the show room floor almost ten years ago. Lasted for the first 500 miles until I took it offroad and had some fun. Haven't looked back since.

mine was clean like that too untill i started off-roading. now its a lost cause.

He's a construction worker, his engine won't stay like that for very long. And as for mine, i haven't been off roading (unfortunately)since i power-washed it haha.
