I don't listen to a 40 year old radio. Dosen't make sence. Just do a turbo lsx motor. Over 1000 HP at the wheels on a stock looking/driving vette. http://www.lingenfelter.com/C620054271038hp.mpg
Its just a 573 not a pro stcok motor. A prostock car witht his motor whould be slow. A pro stock has way more horsepower.
Put a turbo on a 572 and see how it perfroms.
It whould be way faster than a turbo'd lsx.

I love getting over 30mpg hw mpg with 400hp, with my ac,cruse and radio on 
and theirs no reason you couldn't do that with Lingenfelters turbo lsx, well maby hw mpg would drop to the mid to lower 20's

Big Block C5 by GM
The factory has already placed a BB in a C5. GM tech put an all aluminum BB the new "ZL1" style with twin turbos, and all under the hood. It was and or still is a very neat piece. This car {a yellow Vette coupe} was at the Detroit Autorama a couple of years ago in the all GM display. So they do fit!

you're saying you WOULDNT want to see this beast wedged in a C5?

A short deck BBC might fit with the right intake. You'd have to have an LT1 style EFI manifold fabricated.
The tall deck blocks are .4" taller than a regular block (like the 454 and 502) that .4 might not sound like much until you try finding intake manifolds, distributors and headers. I know for a fact that hooker 2" primary headers that fit fine in a 69 Camaro with a 454 will not fit with a 572 tall deck.
With the right parts you can build a short deck block with 540cid. This is the motor I'm building for my 69 Camaro. It has a 4.5" bore bow-tie block and 4.25" crank. I don't knock BBCs they are awesome in cars that fit them, and are an inexpensive way to get huge HP and torque numbers. I just don't know why GM chose to build a tall deck crate motor, it makes no sense to me. There are serious fitment issues in the majority of the classics.

I guess gas mileage is the only thing that you guys have. Do what you want your c5 Maybe clean your wheels they have major brake dust build up.

But I would ask why? I can only think of 2 reasons a person would think of this.
1. for a show car. 2. To build a drag race car. The trouble with #2 is the drive train would never hold up to the tq of the 572. high hp vettes have a problem getting traction now as it is, and the extra weight in the front and combine it with the tq of the 572 and your going to get beat by "smaller" Ls motored vettes who get better traction. Also the Independent rear suspention on a vette is not the best set up for drag racing a straight axel is. are you going to change that also? You would have so much money into a project like this you could probably by a used pro stock car and race it instead. If you wanted to build a killer street car this wouldn't work well either, because you could never maintain traction. I can allmost break traction at will with my stock c5 a unbalanced high tq c5 would be very dangerous. IMO
p.s.
would you like to sell your LS6 cheap

GM should have built a 540" crate instead, this is 95% of the displacement of the 572, but does not have the fitment issues of the tall deck block.

Thats a short deck block. Look at the distance between the head gasket and the top of the water pump boss.

Your car might have to look something like this 
SDPC will be selling the ERL 'Superdeck'. It will easily support 500". We had one on display at PRI. I can't find the pictures right now. It will be pricey though.
