Do you think like Tim "the tool guy" Taylor? More Power! More Power! More Power!
How would you like to turn the key on a crate engine that pumps out 720 hp right out the box? How about a nine-second bracket car without any mods?
Chevy's Big Block ZZ572/720R claims to do just that.
According to GM, when their Performance Parts engineers sat down to design the engine, they were told "To build something nasty".
The ZZ572/720R is a powerful big-block engine that delivers 685 lb.-ft. of torque at 4500 rpm. The short block is built with a 4340 forged steel crankshaft, shot-peened forged steel rods, forged aluminum pistons with full-floating wrist pins, stiff dual valve springs, and a louvered oiling windage tray.
Of course, you could spiff it up by adding a 1090-cfm Demon four-barrel carburetor, tall-deck single-plane intake manifold, HEI distributor, aluminum short-style water pump, and 8 mm spark plug wires and cast aluminum valve covers.

Just be ready to crack the checkbook wide open...the ZZ572/720R will set you back between $14,000 and $19,000 buckaroos. And that's not taking into consideration the cost of all the speeding tickets you're libel to rack up with all that power right under your right foot.
Just remember: more power means more restraint on your part. Good luck!
