CHEVY 409: BIG-BLOCK LEGEND

CHEVY 409: BIG-BLOCK LEGEND
It may have started out as an updated 348-inch truck engine, but it ended up as the CHEVY 409: BIG-BLOCK LEGEND! Two years before the Supercar hype and big-engined midsize cars, full-size ’62 Chevys, powered by 409-inch versions of the 348 W-Series passenger car and truck engine, carried the Musclecar banner for Chevrolet. While the engine first surfaced in the 1961model year, it was a late arrival. Just 142 Chevys with RPO-580 360-horsepower, single-four-barrel (Carter AFB) and solid-lifter-ca...

RPO Z11: CHEVY 427 LIGHT HEAVYWEIGHT

RPO Z11: CHEVY 427 LIGHT HEAVYWEIGHT
By checking off RPO Z11 on a 1963 Chevrolet new car order form, you could buy a factory-built racecar. Only 57 people made that choice before GM pulled the plug. Hemmings’ Mike McNessor writes about the rare RPO Z11: CHEVY 427 LIGHT HEAVYWEIGHT. She’s so fine my… 427? Clearly not 1960s radio gold. But among Chevrolet W-engine enthusiasts, more poetic words were never written. The 427-cubic-inch Mark I big block was part of the factory-lightweight 1963 Z-11 package built to win rounds in quarter...

’65 CHEVY Z16: ONE-YEAR WONDER!

’65 CHEVY Z16: ONE-YEAR WONDER!
One of the highlights of Chevy’s 1965 performance portfolio was the limited-production big-block 396/375 Malibu. Chevrolet had been slow to bring a high-performance midsize car to market in 1965. Toward the end of the 1965 model year, they revealed the potent Z16 Chevelle Malibu SS396, powered by an all-new Mark IV 396 big-block. While somewhat boxy, it was the most powerful car in the Supercar Sweepstakes. But there was a problem. Chevrolet General Manager Bunkie Knudsen’s foray into the marke...

MARK II: CHEVY’S MYSTERIOUS 427!

MARK II: CHEVY’S MYSTERIOUS 427!
The real 427 Mystery Motor, unlike the Z11, was not available in a car, or to the public. You had to have serious NASCAR cred to get one of the 20 built. In the 1960s, Semon “Bunkie” Knudsen always seemed to be one step ahead of GM Chairman Fred Donner’s anti-racing missives. While running Pontiac, he had supported the Super-Duty Group that later, after he left, managed to get 421 Catalina Lightweights to drag racers before the axe fell. Then he moved on to Chevrolet in 1961 and supported the R...

A guide to the engine that made Chevrolet The Number One Team.

’65 CHEVELLE SS Z16: STEALTH SUPERCAR!

Dan Gulino blogs about the rare 396/375 SS Z16 Chevelle, the Supercar that did an end-run around GM’s big-block/midsize car ban. Only 201 Z16 Chevelles were built in 1965 and Ronald Pace has one of the finest examples in existence. The Z16 was Chevrolet's answer to Pontiac's sensational GTO. The ‘65 Chevelle Malibu SS Z16 included a heavy-duty chassis, suspension, axle, and brakes, a four-speed manual transmission, and unique power steering components. The 396-inch L37 engine was conservativ...
