I liked this part....
"CAC: Of course not. Those babies are going a million miles! (all laugh)
MD: Well, I've got parts that went 500,000-mi. but I haven't seen any million mile engines.
CAC: Really! Five hundred thousand! That was with an LS2 or an LS1?
MD: It was actually a truck engine.
CAC: That would make an interesting article for a truck magazine.
JL: Do you have a web site called "TrailBlazer Action Center", by chance.
CAC: (laughs) The 500,000-mile, ah...was it a six-liter, a five-three or a four-eight?
MD: It was a five-three. Actually, we captured two vehicles.
CAC: "Captured?" You mean you just went out and found some owner who'd driven a Silverdo that far?
MD: Oh yeah. We had a hard time buying his trucks (there were two) from him. He didn't want to sell 'em.
JL: Before we leave the block-and this is part of cylinder heads, too-I think it's worth noting the compression ratio increased from ten-one to ten-point-nine. Due to improvement in combustion efficiency as well as in the control system; we're able to tolerate that. It has helped, not only in improving power, but in fuel economy, too. Compared to Gen 3, our brake-specific fuel consumption (BSFC), on average, between the two test points we look at for most city and highway driving, went up about 3%."
And that engine was a truck that was based off the LS1. Nice to know if you take care of a corvette, or chevy/gmc truck, it will last as long as you want.
Also maybe I missed it, I scanned a little. But what if the battery dies in the car, how do you getinto the car to pop the hood and put a new battery in? I know lexus and soem other car companies are using the keyless design so I know I am not the first to think of this little problem.
