As an engine builder i think the gm crate engine is a great sales item for their dealers. Not only is it flashy, but it keeps the gm , ford, or dodge dealers garages busy, and i see alot of sales of parts or complete engine sales after the customer has had trouble with them. the gm garages here bring me all kinds of things to fix for them. I currently have a 502 that burns oil with only 2000 kms on it, and a zz430 with "piston noise". I get alot of the 3.1 or 3100 3800 4.3, 4.8, 5.3, and 6.0 litre engines that need to be bored and new pistons because of factory "piston noise". Usually it only means boring the block to .010 or even honing it to .005 over. People need to realize that the engines carrying the "gm" "ford", or "mopar" logos on them new and sold from their performance catalog have never seen a company owned assembly plant. All these engines are cast, machined, and assembled by "farmed-out" contracts.
