Chevy Big-Blocks—the Mark IV and a New 427

by Ross Mills

Chevy’s Mark IV engines roared into the automotive scene with a bang, featuring a variety of big-block beasts. The 396-cubic-inch version made waves in the Corvette and Chevelle with its 375 hp output, while the 427-cubic-inch monster, available in the Corvette and the unassuming Biscayne, delivered neck-snapping performance. Dubbed the Bisquick, the Biscayne transformed from a taxicab lookalike to a speedster with 425 hp. Even with aluminum heads reducing weight, these engines proved old-school horsepower ratings were more optimistic than realistic.

Rev up your engines for a ride through the iconic Pontiac GTO era, 1965-1967! This muscle car’s journey starts with a sleek redesign in ’65, adding a functional hood scoop for that extra “vroom” and an optional tachometer for those who like to live on the edge. In ’66, the GTO strutted its stuff as a standalone model, offering pillared and pillarless options, plus a convertible for those who like wind in their hair. By ’67, it boasted a 400 CID engine and new safety features, making it both a beast and a beauty on the road!

Chevrolet’s first big-block V8, the “W” series, roared to life in 1958, stepping in like a heavyweight champ to lift increasingly hefty cars. With its unique scalloped rocker covers and offset valves, this wasn’t your grandma’s engine—unless she liked her Sunday drives with a side of 350 hp thrills. The “W” series went from a modest 348 cubic inches to a hulking 427, proving that in the engine world, size does matter. It’s like the Hulk of engines, but with less smashing and more horsepower.

The 1966 Pontiac GTO, affectionately dubbed “The Goat,” didn’t just break sales records; it kicked them to the curb with a whopping 98,946 units sold. Despite Pontiac’s attempts to market it as “The GTO Tiger,” the quirky nickname stuck like gum on a shoe. With two beastly V8 engines and four transmission options, this car was a gearhead’s dream. The tri-power option met its demise midway, replaced by the XS engine, but it didn’t quite roar with consumers. Only about 35 XS beasts were unleashed by the factory!
