1970 Chevelle SS

How to spot a genuine SS Chevelle / El Camino
by: Daniel Carr (Part 3)

In 1970, there were two different SS packages available. One was the “Z25″ SS-396 and the other was the “Z15″ SS-454. There were only two engine choices for the SS-396: the 350 and 375 horsepower versions. It was a confusing year for 396 buyers. The 396 engines now actually displaced 402 cubic inches, but were still called a “396″ when installed in an SS. There was also a new 330 horsepower “LS3″ big-block “400″ engine option available for the non-SS Malibu and El Camino Custom. To confuse things even further, there was a 400 cubic inch 2-bbl small-block available (only in the ‘70 Monte Carlo).

The Malibu “400″ big-block was also actually a 402, and was basically an overbored version of the 325 horsepower 396 motor that had been available on the ‘68 and ‘69 SSs. The “Malibu 400″ package, produced from ‘70-’72 on the Chevelle and El Camino is fairly scarce today. The reason is that many of these big-block vehicles have been converted to SS clones. In stock form, the Malibu 400 and El Camino 400 carried “400″ emblems on the fenders.

A very limited number of SS Chevelles with the 375 HP 396 and the “L89″ aluminum heads were produced in ‘70.

There were two engines available for the ‘70 SS-454 : the 360 horsepower “LS5″ and the 450 horsepower “LS6″. The ‘70 LS5 Chevelle is actually rarer than the ‘70 LS6 Chevelle. The LS6 was only available in the ‘70 Chevelle, the ‘70 El Camino, and the ‘71 Corvette. It was never available to the public in *any* other cars. The ‘70 LS5 motor used in the Corvette was identical to the Chevelle LS5, but for marketing reasons the Corvette rating was 390 horsepower. There was purported to be one known LS6 Chevelle with the L89 aluminum head option, but it is now generally believed that this car (and its documentation) is fake. Chevrolet also had an experimental LS7 engine that was supposed to be available in the ‘70 Corvette, but never materialized. However, the LS7 heads were available over the counter at GM dealers in ‘71 and ‘72. No factory built LS7 cars were ever sold to the public.

The ‘70 & up SS now had a completely different dash than the non-SS models. The ‘70 SS would have either “SS/396″ or “SS/454″ emblems on the fenders (and on the tailgate of the El Camino). The Chevelle SS had a white “SS” logo in the black rubber pad on the rear bumper. Both the Chevelle SS and El Camino SS had a large “SS” grille emblem (without any engine size).

The SS models also had a hood with a large bulge in the rear center. Hood stripes were an extra cost option with this hood. There was also a “Cowl Induction” option available. It had “Cowl Induction” emblems on either side of the bulge and a door on the top of the bulge that would open automatically when the engine needed extra air. The Cowl Induction option was NOT standard on any SS – it was always an extra cost item. The Cowl Induction option came with hood stripes. You could, however, delete the Cowl Induction stripes at no cost.You could get the stipes without the Cowl Induction option (at additional cost). All of the ‘70-’72 SS cars came with hood pins, except for some of the early ‘70 models (those built around April of 1970 or earlier) that were not ordered with Cowl Induction.

The ‘70 SS came with the same wheels used on the ’69s.

1969 Chevelle SS For Sale

How to spot a genuine SS Chevelle / El Camino

From 1969 on, the SS was no longer a separate model. Instead, it was now an “SS” option package added to a 300 Deluxe model, Malibu model, or El Camino Custom model. 1969 was the only model year that the SS package could be ordered on the base model Chevelle 300 Deluxe (as a 2-door coupe or a 2-door post sedan). The only SS option in ‘69 was the “Z25″ SS-396 package. The ‘69 and up cars are harder to authenticate because the VIN can not be used to confirm if the car is an SS. 

There were two colors that were exclusive to the ‘69 SS. “Monaco Orange” (code 72) and “Daytona Yellow” (code 76). If either of these paint codes appear on the cowl tag (and the cowl tag is genuine) then that would prove the car to be a genuine SS. 

VIN tag doesn’t tell you much

If someone had a nice ‘69 Malibu, and a rusted out ‘69 SS, it would be easy for them to simply move the SS equipment over to the Malibu. As long as they did not alter or move the VIN plates or cowl tags, this would be perfectly legal, and since the VIN tag doesn’t tell you much, there would be almost no way for you to know. 

From ‘69 on, single-piston disk brakes were STANDARD equipment with the SS package. These brakes are easier to find parts for than the earlier four-piston disk brakes. 

Chevrolet literature indicates that the only way to get a 396 was with the SS package. However, there appears to be at least one late-production Chevelle that was built with a 396 and all the required SS equipment, but the “Z25″ SS-396 option was not listed on the car’s build sheet. It is believed that this car came from the factory with “SS” emblems, but that is not 100% certain. 

Again in 1969, the only available SS engine was the 396 (in the same flavors as in 1968). In 1969, however, it was possible (if you knew who to talk to) to order something called a COPO 427 Chevelle. COPO stands for “Central Office Production Order”. The COPO program allowed dealers to order equipment that was not usually available (such as special paint, special engines, etc.) Unlike the ’68s, the ‘69 Chevelles had their 427 engines installed at the FACTORY, not the dealership. This makes the ‘69 427s more legitimate in the eyes of collectors today. You didn’t necessarily have to go to Yenko or some other special dealer in ‘69 to get a 427 Chevelle. Your local dealer could usually get you one if you filled out the right paperwork. While the ‘69 COPO 427s had basically the same equipment as the SS-396s, they were not generally considered SSs because they did not have any external “SS” or “427″ identification. They were the ultimate sleepers. Any genuine ‘69 COPO 427 Chevelle is quite valuable today. There are also unconfirmed reports of a ‘69 COPO 427 El Camino. 

In addition, there was an “L89″ aluminum head option available for the ‘69 375 HP 396. Few were ordered. 

1969 SSs had “SS/396″ emblems on the front, back, fenders, door panels, on the dash above the glove box, and on the standard SS steering wheel. The ‘69 SS also had the twin-bulge hood like the ’68s, but the bolt holes where the hood hinges attached were slightly different. The ‘69 SS came with 14″ SS wheels with “SS” center caps. The ‘69 SS stripe option consisted of a black, white, or red stripe which ran along the upper body sides. There are also reports of a few ‘69 SSs with dealer-painted hood stripes, similar to the stripes used on many ‘70-’72 SSs. 

Another rare car, produced only in ‘69, was an SS Chevelle built on the 2-door post sedan, the “Chevelle 300″. This was the only year that a 2-door post sedan SS was produced. Most of the ‘69 SSs, and all the ‘70-’72 SSs, were built upon the 2-door Malibu pillarless coupe.
