Vehicle Specs

1970 Chevrolet Chevelle LS6 454 450Hp #'s Matching. A restoration that tried to keep as much of the original parts as possible in use which we believe was done around 2000 as the previous owner purchased the car in 2011 when he was told the car was restored 10 yrs prior. He purchased the car in 2011 at the Atlantic City NJ Classic Car Auction. He stored the car and drove it less then 500 miles a yr and was stored in a climate controlled garage. The most important bit, the matching-numbers 454ci (7.4-liter) LS6 V8, was saved, and it is presently fitted under the white stripe hood of the monster, working through a 4-speed muncie transmission and rated at 450 hp and 500 ft/lbs of torque. Connecting wheels to transmission is a CRV Coded LS6 Rear End. Code CRV decodes as a 3.31:1 axle ratio with positraction and was one of the three ratios that you can get with an LS6. Others included a CRU Code 3.31:1 Non-Positraction and CRW Code 4.10:1 with Positraction. We do believe that the rear is original to the car although we believe the ratio has been changed and is no longer a 3.31:1.

But not only the engine itself is original - so are things like the smog system, original intake manifold, distributor, heads and Holley carburetor.

The body panels we believe are the ones the car rolled off assembly lines with decades ago, restored and hidden under a 3-stage base and clear coat in the native Forest Green color. Offsetting that is a black interior (also the original interior color) with bucket front seats and no center console.

The LS6 used the same block as the LS5, however a 800-cfm Holley four barrel bolted to an aluminum manifold replaced the Rochester Quadrajet. The LS6 featured a beefy bottom end with four-bolt mains, forged steel crankshaft and connecting rods with forged aluminum, 11.25:1 compression pistons. Because of the LS6's high (6500) redline, deep groove accessory drive pulleys were necessary. Thanks to new Federal emission standards, the LS6 was hobbled with the primitive Air Injection Reactor (A.I.R.) pump plumbed into the tops of the exhaust manifolds that injected additional air into the exhaust system. By doing so, it reduced the products of incomplete combustion (hydrocarbons and carbon monoxide) and further combustion occurred in the manifold and exhaust pipe in the presence of this oxygen-laden air. Only the Holley-equipped LS6 received the A.I.R. system, which was one of the first items removed by owners on taking delivery from the dealer.

Buying an LS6 Chevelle required the customer to purchase mandatory options, and it wasn't cheap. The $503.45 RPO Z15 SS 454 package consisted of bright engine accents, dual exhaust with bright tips, black painted grille, wheel opening moldings, power front disc brakes, special rear suspension and F70 x 14 tires on 7-inch rims. The rear bumper had a black insert while up front the SS got a “power bulge” hood. Also part of the package was the base 360 horse LS5 with heavy-duty battery. From there the buyer selected the RPO LS6 454 engine that cost an additional $263.30 and either a M22 ($221.80) or M40 ($290.40) to add to the bottom line. Just to get the Bow Tie's biggest bruiser cost at least an additional $988.55 to a base price of just over $2,800. By the time other options were added, the SS 454 Chevelle could cost well over Four Large.

The standard interior featured a bench seat regardless of transmission. When the optional bucket seats were ordered, a center console was also available. Unlike most carmakers that would use the same basic dash layout in all series models, the 1970 SS Chevelle received a different instrument panel setup than the base Chevelle or Malibu models. Borrowed directly from the new Monte Carlo, the large, flat-faced panel housed the gauge package, which featured three large circular gauges for the tach, speedometer and clock with smaller gauges flanking them. To the right was the HVAC controls, radio and lighter.

The exterior of the SS 454 Chevelle featured sculptured lines above the wheel openings that pulled the car's look downward. The blacked out grille was split horizontally and dominated by a large SS emblem in the center. Chevrolet offered wide “Stereo Stripes” that ran the length of the hood and deck lid and included Cowl Induction, which featured a vacuum-operated door at the rear of the SS hood. It fed air from the high-pressure area at the base of the windshield to the big Holley carb.
