Monster motors were the order of the day in the late 1960s, and GM's 427 was a part of that class. The drawback to a big-block's burly output was, and still is, the increased weight of the engine. While big blocks are a hoot for straight line shenanigans, a small block car is often a better all-around performer. That goes out the window for most of us upon tapping that vast well of torque, and there was a solution direct from GM. The ZL1 was a 427 rendered in aluminum to save weight and carried a 430 horsepower rating. The ZL1 is the stuff of legend, commanding the sharp intake of breath when mentioned with the Corvette, and reverent silence should the COPO Camaro be cited.
GM Performance Parts is whipping up a limited run of all new ZL1s, built from the same tooling as the original. A total of 427 of the Anniversary 427 Big Block engines will be produced, creating a new piece of automotive unobtanium while leaving the ZL1 mystique intact. You might even argue that the new engine run will add to the lore. We'll get to see just how much of a clamor there might be for these new engines when the very first Anniversary 427 Big Block crate engine, serial number 001, goes up for bid at the upcoming Barrett-Jackson auction. The remaining 426 engines will be available soon from GM Performance Parts dealers, and will likely be snapped up like rabid moms going after Hannah Montana tickets.
