I'll see your 2 cents and raise you a nickel!

I have about $2500 in the LS1 motor and Magnacharger Radix supercharger. Using an LQ9 (escalade motor) instead of the LS1 with this supercharger won't net any more hp, but will have a bit more torque. The added 20 cubic inches difference for the 6.0 over the 5.7 pushes this specific supercharger out of its max efficiency range. The LS1 will allow me to spin this baby into higher rpms for more horsepower. Then add in the fact that the aluminum block of the LS1 weighs almost 100 pounds less than the iron block LQ9, and it makes my decision a bit easier.

If I decide to use a larger motor, it will either be an aluminum LS2 6.0 block, the newer L92 6.2L block, or a lot larger cubic inch LSX iron block.

A friend of mine bought a Magnum SRT8 last year and with no mods, gets an average 24mpg. It has that advanced Multiple Displacement System and is incredible. Why doesn't Chevy build something like that?
They are doing it right now and expect to see it in the dealers early next year: Pontiac G8.

Re: LS7 Engine

Re: LS7 Engine

The LS-6 BB was 450hp...the LS7 was considerably more depending on how you optioned it.

You are right about it never being a production motor...it was special order only.

Re: LS7 Engine

Who says LS motors can't be made pretty? I have to disagree...
