    INSTALLATION NOTES:
  • Due to crate fitment, the carburetor is shipped in a separate box and needs to be installed by an engine installer
  • Clutch linkage boss is now drilled and tapped. When using cast-iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads for clearance
  • Requires addition of starter and fuel pump (not included)
  • Gen VI tall-deck block has machined mechanical fuel pump boss
  • Comes with a 14'' automatic transmission flexplate. Requires internally balanced flywheel for manual transmission applications
  • Designed for pre-1976 street vehicles or any off-road vehicle
  • Not intended for marine applications
  • You do have a strong transmission and rear axle, don't you?
  • Distributor with melonized steel gear MUST be used with steel camshafts, or engine damage will occur.

    The ZZ572/620 is the ultimate expression of Chevrolet Performance's engineering capability. They build the ZZ572 with huge 4.560-inch bores and add a forged 4.375-inch-stroke crankshaft. To make sure those cylinders are packed with every cubic centimeter's worth of atmosphere, we use a camshaft with incredible 0.632/0.632-inch lift and 254°/264° duration specifications.

    Aluminum rectangular-port heads with 310cc intake ports complement the airflow capability offered by the big-bore bottom end. They also feature 118cc raised exhaust ports and 118cc combustion chambers. The valves are big, too - measuring 2.250 inches on the intake side and 1.880 inches on the exhausts.

    Chevrolet Performance delivers the ZZ572/620 Deluxe with an 850-cfm carburetor, HEI distributor, aluminum water pump, and distinctive orange powder-coated valve covers that proudly proclaim the 572 legend.

    I have a 1972 corvette will the old 454 headers bolt on

    Asked by: cory269
    You will need to check, this is a tall deck engine and the headers will be in a different location than the original.

    You can get this all under the factory hood.
