Even the Ford guy voted. Just cuz I picked this little gem don't hold it against it.

20" HREs all around, IRS rear in a custom frame. I just see your car as a a true protourer. A comfortable smooth street car that is still very competent on a track but not a track first focus.

Sure the supercharged motor is heavier but it's not like you went on a weight savings binge anywhere else. Why not have smooooth power and good milage for those road trips with a bunch of on demand low end grunt.

700hp it will still be a missile

Makes you want to rethink building the 'iron lung' doesn't it?

I chose the 427/440 option because the sound of that thing at WOT will bring a tear to the eye of God himself.

Very sweet setup Greg..I don't know how I missed those pics/specs. Cant beat the supercharger power and looks with ability to keep drive-ability, mileage and have 700 HP.

I GUESS you know what my vote is :-)

[Steve Chryssos]

The blown 376 will fill your Chevelle's cavernous engine bay so nicely. And they are very well built engines.

I voted 427/440. I'm a big fan of the 427.
Although, that 376 with the supercharger looks pretty tasty too! You have some deciding to do bud. Good luck.

Nope Just reminds me you need a supercharger on an LS to make the same hp

I do like your name for my little daily driver motor "Iron Lung"

Not really, here is a 700Hp NA LS7 that runs on pump gas.

If I recall yours used racing fuel to achieve those numbers. Actually, there was a 427 side oiler that dyno tested before my LS3 418 with Harrop TVS2300. I used 93 octane pump gas and my Hp numbers were much higher and with a peak torque of 787 ft/lbs at 3900. Never tested with racing fuel..
