    A 10-second car is quick, but the ZZ572/720R could achieve that with a couple of its spark plugs left in the pits. It is the king of all Rat engines and is capable of pulling your bracket racer or heads-up challenger down the 1320 in the 9-second range.

    The ZZ572/720R's true value lies in its ready-to-run status when delivered. Rather than waiting weeks for a racing engine shop to build a custom combination, we deliver the ZZ572/720R fully assembled; just bolt on the included Dominator-style 1150-cfm carburetor, along with a starter and fuel pump (not included) and you're ready to go.

    The ZZ572/720R is built with the best stuff we can find, including an all-forged rotating assembly, rectangular-port aluminum cylinder heads with 113-cc intake ports, and 2.25/1.88-inch valves. There's also a solid roller camshaft with 0.714/0.714-inch lift.

    If you're building the ultimate dual-purpose car, the ZZ572/720R is suitable for limited forays on the street. It has a 12.0:1 compression ratio, so make sure you've got access to 110-octane gasoline before hitting the local cruise night!
