🔍 It's the little things that separate a good restoration from a great one. Anyone can paint a car... but the details underneath tell the real story.

At Inline Tube, we manufacture factory-correct brake lines, fuel lines, transmission lines, fittings, clips, hardware, and restoration parts that help bring classic cars back to their original glory.

In the late 1960s, while Chrysler had the Hemi and Ford had the Cammer, Oldsmobile's engine lab was quietly developing something neither competitor had: a four-valve-per-cylinder production V8. The W-43 was a 455-cubic-inch Oldsmobile V8 with 32 valves, four per cylinder, pent-roof combustion chambers (not hemispherical, despite the look), centrally located spark plugs, a unique block casting with four-bolt mains and a raised camshaft position, and a custom valvetrain designed to handle four valves per cylinder off a single camshaft in the block. The standard 455's rotating assembly (bore 4.126", stroke 4.25") was retained. If it had gone into production, it would have been the first four-valve American V8 sold to the public. It didn't. The muscle car era ended first.

At least two W-43 engines were built. One was sent to Petersen Publishing in Los Angeles for valvetrain stability testing and photographed for Car Craft and Hot Rod. When the program was canceled, Oldsmobile reportedly didn't want to pay shipping to get the dead engine back to Michigan. It was supposed to be thrown away. The parts never made it to the dumpster. They disappeared for decades. In 2011, incomplete W-43 components surfaced on RacingJunk.com. James Kryta, co-founder of Inline Tube and a serious Oldsmobile collector, bought them. One head was missing. The valvetrain was gone. No intake manifold. No valve covers. Half an engine.

Kryta sat on the parts for over a decade before meeting Ed Koerner, former executive vice president of GM's North America engineering operations, who had started his career in the Oldsmobile engine lab in 1969, during the tail end of the W-43 program. Koerner guided the resurrection. A new cylinder head was cast. A new aluminum intake manifold was cast to house a 750-CFM Rochester Quadrajet, matching the original. New exhaust manifolds. New valve covers. Some components were 3D-printed. The engine was assembled, put on a dyno, and fired on the first try. It was then installed in Kryta's 1970 Oldsmobile 442 W-30 and debuted at the 2024 Detroit Autorama.

The W-43 never won a race. Never powered a production car. Never appeared in a showroom. But its four-valve pent-roof head design reportedly inspired Oldsmobile's Quad 4 engine, which debuted in 1987 and became one of GM's most significant four-cylinder programs. The idea that started in the 455 engine lab in 1969 resurfaced eighteen years later in a 2.3-liter four-cylinder. And now, fifty-five years after it was built and supposed to be thrown away, the W-43 runs again. In a 442. Where it was always supposed to be.
