| |  |  | | So our 540 Extreme isn’t a big enough big-block for you? Let us introduce the 572 Extreme. With over 690 rampaging horsepower and 700 traction-annihilating lbs/ft of torque, all on pump gas, have we got your attention? Mixing all of the right severe-duty parts into a potent, streetable combination, along with precise machining and balancing, all hand-assembled with the skill of more than 20 years of craftsmanship, you have an engine that makes more normally-aspirated power with a single 4v carb than any pair of tires can hold. And to prove this power, each and every engine we produce is broken-in, tuned and tested on our in-house dyno, so you have a guarantee of power and durability. Also take a look at our list of options to personalize the 572 Extreme to your taste. | |
