750HP,
I don't know the price yet of Chevys latest crate engines but if you want 100 additional HP and can get a hold of Raceing Gas.

ZZ572/720R
…AND THE R STANDS FOR RACE

Engineered by GM Performance Parts and GM Racing exclusively for sportsman races, the new ZZ572/720R is built around an all-new Gen VI tall deck Bow Tie cylinder block. This all new race block is filled with a forged 4340 steel crank with 4.375 inch stroke, shot peened forged 4340 H- beam rods, and forged aluminum pistons with full floating wrist pins. Plasma moly piston rings are standard is the screened and louvered windage tray. GM’s first purpose built drag race engine filled with hard core race parts for hard core performance and long term durability.

The redesigned rectangular port aluminum cylinder heads result in a race gas only 12 to 1 compression ratio. A solid roller cam with 0.714 inch lift actuates the stainless steel valves. And, of course, hardened chromemoly retainers, roller rocker arms, and duel valve springs are used to complete the valve train.

A new Gm tall deck single plane intake manifold and 1095 CFM King Demon carburetor deliver enough air and fuel to make the 720 horsepower at 6250 RPM. Ignition is handled by a multiple spark discharge ignition. And an SFI approved torsional damper is installed at the factory. Out of the crate and into your racecar – it’s that simple.

Race gas fueled, high revving horsepower, all from GM, the ZZ572/720R is the engine that will get you down the track consistently, pass after pass, season after season.

Available in a short block, long block and deluxe engine configurations in 2003

Reptyl,
I like the picture of the McD's Cobra.
