Fits On/Installation Notes:
Our baddest, most powerful Big-Block engine is ready for the strip!
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 ZZ572/720Rs 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 youre 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 113cc intake ports and 2.25/1.88-inch valves. Theres also a solid
roller camshaft with 0.714/0.714-inch lift.
If youre 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 youve got access to 110-octane gasoline before
hitting the local cruise night!
