Was looking to possibly buy a Shelby

Maybe you should show me another engine that makes the same (or more) horsepower and gets the same (or better) economy.

The LS7 is just fine. It weighs around 450#, makes 505bhp, and will get 26mpg on the freeway in my experience.

Oh, it has a 5/100K mile warranty, too.

Go find me this "modern" engine that can equal that for $15K.

It doesn't exist.


Did you actually do any research on why the corvette has the engine that it does?

Have you actually compared the physical weight of the LS series engines (about 450#) to their competitors? Have you compared mileage? Have you compared power under the curve?

Noone gives a damn about displacement, it's a means to an end. What designers care about is power/weight, and the LS-series engines are KING in that department. Compare them to any N/A engine out there and you will find that the only one's that better them in physical power/weight cost roughly $50K and are found in AMG's. The LS7 costs $14K.

Now you bitch about mileage. Bring up skip-shift. Bring up all that crap.

Well why don't you go look at a 'vette with an LS3 and a slush-box? It gets 1mpg less in the city than the stick. It has no CAGS. It has an efficiency-robbing hydraulic tq converter.

CAGs. It's not doing all that you think it is.

Just because the LS3 and LS7 use old concepts does not mean that they are not cutting edge engines. Your tires are still round and all that. Doesn't mean the rubber around the rim is as old a design as the wheel-shape, if you get the drift.
