• 1964 Vintage Buick Electra 225 Convertible

A powerful GM Performance Parts ZZ572 crate engine is the 620-horsepower heart of a beautifully restored 1964 Electra 225 – one of the famed Buick “Deuce-and-a-Quarter” full-size luxury vehicles that have achieved popularity with collectors and urban customizers. The ZZ572/620-powered Electra 225 was displayed among 11 new Buick Lucerne concepts at a special event held during the Specialty Equipment Market Association (SEMA) convention.

 Along with the 620-horsepower engine, the modified Electra 225 features a Hydra-matic Turbo 400 automatic transmission and a custom radiator that’s outfitted with twin electric fans. The car rolls on chrome 20-inch Boss Motorsports “312” five-spoke wheels and Michelin Pilot Sport tires. The body and interior of this imposing “Deuce” retain their factory-stock good looks, wearing a new coat of factory white paint and re-chromed trim. The top is white, with a black boot cover. The interior also is black, with the vinyl upholstery re-done to a factory appearance.

“The growing interest in Lucerne among the tuner market inspired us to take one of the most recognizable classic Buicks and build a companion for the 11 Lucernes displayed at SEMA, said General Manager Steve Shannon. “Our touch on an old-school classic like the Deuce highlights the potential consumers have with GM Accessories.”

The ZZ572/620 crate engine – GM Performance Parts number 12498793 – however, is far from factory-stock. It’s the largest-displacement big-block crate engine offered by GM Performance Parts – and the most powerful engine designed for street use. It features cavernous 4.560-inch bores and a 4.375-inch stroke, with forged rotating components. Aluminum, rectangular-port heads provide tremendous airflow and the engine aspirates through an 850-cfm Demon four-barrel carburetor. A hydraulic roller camshaft and a 9.6:1 compression ratio contribute to docile street manners and pump gas friendliness – with a tremendous reserve of 650 lb.-ft. of torque only a tip of the right foot away. The engine also wears a GM Performance Parts front dress kit and chrome air cleaner.

Cross member and steering gear modifications were required to install the big-block engine. It is one of approximately 7,200 Electra 225 convertible models sold in 1964 and it originally was well optioned from the factory, including air conditioning – a relatively rare combination with a convertible in its day.

More than 40 years after it left the factory, this updated Deuce retains its vintage style while delivering a thoroughly modern blast of performance.

Apart from greater length, rooflines and rear-quarter panels really made Electras stand out from other standard Buicks. The razor-edged roofs seen on 1962-1964 Electras were softened a bit, and rear roof ars wrapped around slightly at the back to impart a hint of limousine-style privacy.
