Frequently Asked Questions

• How much torque does a ZZ4 hotcam have?

  One package was a ZZ4 that they installed the LT4 HotCam into. It made 3 extra ponies and lost 2 ft/lbs of torque. Not even worth the time to swap it. They also had a package where they swapped the stock ZZ4 heads for a set of FastBurn heads. That picked up 30HP and 7 ft/lbs of torque with no change to the cam.

EOLine: This is the most distinctive part of the ZZ method.

• What kind of engine does the performance zz427 have?

  Chevrolet Performance has recreated that classic Big-Block combination in the Z427/480 - including the 480 horsepower rating (and it just might be a little on the conservative side, too). Like the original, it features a forged steel crankshaft and high-flow, oval-port aluminum cylinder heads.

• What kind of spring does the zz427 / 480 use?

  Wrapped around them are ovate-wire, beehive-style springs that play a major role in valvetrain stability. Whereas the original L88s used a dual-spring with a third, inner damper spring, the ZZ427/480’s beehives provide adequate control, even with the faster ramp speeds of the roller camshaft.

• What makes the zz427 / 480 better than the L88?

  Whereas the original L88s used a dual-spring with a third, inner damper spring, the ZZ427/480’s beehives provide adequate control, even with the faster ramp speeds of the roller camshaft. Even so, their lighter mass allows for less pressure, heat, and wear on the springs.

• What's the difference between a corvette and a zz427?

  The ZZ427/480 uses a dual-plane intake that is slightly higher than the factory Corvette version. Another benefit is the 770cfm Holley carburetor that utilizes vacuum secondaries and center-hung floats. An electric choke provides better low-temp operation and makes itself scarce when not needed.
