Top End Engine Kit, Power Package, Intake, Heads, Cam, Timing Chain, Head Bolts, AMC, 448 HP-512 TQ, Kit

The Edelbrock Total Power Package concept is second to none. To make things easier in parts selection, Edelbrock has taken the guesswork out of top-end component selection by actually placing the power package components together in complete kits. They include almost everything you need to make serious horsepower. These kits are available with different cams, intakes, and heads to deliver the torque and horsepower you're looking for. Horsepower output will vary depending on combinations of accessories used. This 448 hp 290-401 AMC top-end engine kit is application-specific.
