The most powerful big-block engine that Chevy produced for 1970 was the 450-hp LS6. Available only in the Chevelle, it had four-bolt main bearings, large-port/large-valve cylinder heads, solid lifters, a low-rise aluminum intake manifold and Holley four-barrel carburetor. Cowl induction, which gave the engine a breath of cold air, was a separate option designated ZL2. It came with functional hood pins and body stripes.
Some have suggested that the LS6 was underrated; actually producing as much as 500-hp, citing empirical evidence on competition cars. In any case, it was Chevrolet’s most powerful 1970 production engine. In this car it is teamed with a Muncie M22 “Rock Crusher” four-speed manual transmission. The most sturdy of the rock-crushers, it is a close-ratio gearbox and very desirable. It drives a 12-bolt 3.73:1 Posi-traction rear end.
Of course, there is more to a real performance car than simply a big engine. The interior is designed and laid-out to give you the feeling that you are truly in charge of the muscle machine. The SS suspension also assists in applying the grip to the tarmac and helps keep it pointed in the right direction, particularly when hustling the car through the corners.
Other equipment on the car includes power steering, power brakes, AM radio with embedded windshield antenna and windshield washers. The bucket seat interior is done in black vinyl and has the SS center console and all appear to be in excellent condition.
Painted Cranberry Red with black center stripes, it has excellent contours and paint. The brightwork is all very good. The engine compartment and undercarriage are absolutely spotless, substantiating that the low-figure odometer reading is test and maintenance miles only. This example sports correct Goodyear Poylglas tires on SS wheels, cowl induction hood, hood pins and stripes, and comes with an original owner’s manual and brochure.
“The performance starts as soon as you’re seated,” said the 1970 Chevelle SS brochure. This SS 454 Chevelle is bound to get a standing ovation.
