The 1962 Buick with the Wildcat 401/445 engine was arguably Buick's first performance car, although it was born in the Wildcat as more a luxury sports coupe than all out performance. Nevertheless, it began Buick's quest for power and even lended its name to several Buick engines of the mid sixties. The first Wildcat (officially named the Wildcat Sport Coupe) was part of the Invicta line, but included front bucket seats, a console, tachometer, and a rear floor lamp. It's body style was classy and attractive. Buick engineers adjusted the suspension to improve the handling of the Wildcat. Highlights included a frame which carried boxed cross-members with heavy side rails, coil springs on all four corners, and oversized 10 inch drum brakes. Standard power was the Buick LT401 cid V8, rated at a strong 325 bhp. Although this engine was also available in the regular Invicta line, the Wildcat came with a standard 3.42:1 rear end. A 4.45:1 rear end was optional for those wanting even more drag strip performance. Marketed as a "family-sized sports car", approximately 2,000 were sold. The Buick Wildcat was a full-size automobile produced by the Buick Division of General Motors from 1962 to 1970. It took its name from a fiberglass-bodied 1953 concept car. For its first year, the Wildcat was a 'sub-model' within the Buick Invicta series, mating the Invicta's longer full-size two-door hardtop Buick body (known as the "sport coupe," body production code 4647) with a high-performance 325 hp (242 kW) version of the 401 cu in Nailhead V8, known as the Wildcat 445 for producing 445 ft lb of torque. The Wildcat did share the LeSabre's and Invicta's trio of portholes on the front fenders, a design cue lasting only through the 1963 model year.
The 401 cu in (6.6 L) 401 was Buick's muscle car powerplant of choice, and was found in the company's Skylark Gran Sport and Buick Wildcat, among others. As unlikely as it seems, the air cleaner for the engine is annotated with "Wildcat 375" "Wildcat 410" "Wildcat 445" these inscriptions indicated not the cubic inches displaced but the ftlbf of torque produced by the engine. The "Wildcat 410" was the 2-barrel carbureted engine that was standard on the 1962-63 LeSabre. The "Wildcat 375" was a no cost option on the 62-63 LeSabre that had lower compression to run on regular fuel. Another Buick V8 had "Wildcat 375" written on its air cleaner but it wasn't a "Nailhead", it was the 4-barrel version of the 66-67 small block Buick 340. The "Wildcat 445" had a single 4 barrel carb. It was the standard engine on the Invicta, 1959-66 Electra, 1962-66 Buick Wildcat, 1963 Riviera and 1965 Riviera (the 64 and 66 Riviera models had a 425 in engine with a single 4 barrel carb. named "Wildcat 465" as standard equipment).
