1969 Chevelle SS

For 1969, the SS 396 became an option package on all Chevelles. Therefore, it was possible to order the SS 396 package on everything from the Malibu sport coupe (the most popular) and convertible to the Chevelle 300-series hardtop and pillared coupe and the El Camino pick up. All Chevelles got new styling which included new tail lamps. The 396 returned in 325, 350, and 375bhp tune but still suffered from poor handling and four-speed linkage. Late in the 1969 model year, the 396 was bored out to 402 cubic engines, reportedly to meet new emission standards. The official name and power ratings were not changed and the Chevelle SS remained one of the most popular muscle cars of the era. Of particular interest to drag racers was the availablity of a number of limited edition Chevelles. Known as COPO Chevelles, these Chevelle's were specially ordered from the factory by certain dealers or well- connected customers with standard L72 427 V8s rated at 425bhp. An estimated 323 Chevelle COPO 427s were built, all of which were often devoid of badges or other indications of the power that resided underneath.

1969 Nova SS

There were no major changes for 1969 for the Chevy Nova SS. The standard SS package with the 350 cid V8 cost just an extra $280 above a base Nova coupe and included a special suspension, red stripe F70x14s, and power front disc brakes. To replace the 350 with the L78 396 V8 375 bhp engine cost an extra $500, but even with the $184 close-ratio four speed transmission, $43 limited slip differential, and excellent $84 fast-ratio power steering, the total cost was still under $3,500. In 1969, a total of 5,262 Nova SS were built with the 375 bhp 396 while another 1,947 were built with the 350 bhp 396 engine. Total SS production for totaled 17,654 units.

The biggest news for 1969 was the very limited Yenko Nova 427. Unlike COPO Camaros and Chevelle's, the Yenko Nova 427 engines were not factory installed. Instead, Yenko ordered Super Sport Novas equipped with the 396 V8 with 375 bhp and promptly dropped in the Chevy 427 with 425 bhp at the dealership. As with the Yenko Camaros and Chevelles, Yenko rated the 427s at a realistic 450 bhp. Yenko Nova 427s were available with either the close-ratio Muncie four speed with Hurst linkage or a Turbo Hydra-matic with Hurst Dual-Gate shifter, mated to a heavy-duty 4.10:1 Posi axle. The Novas had 14x7-inch wheels, as opposed to the 15x7s on the Yenko Camaros and Chevelles but were available with the usual Yenko supplied headers, Atlas mags, and tachometer. On the exterior, they were dressed up with Yenko stripping, 427/Yenko badges, and "sYc" headrests. Built in both 1968 and 1969, they were extremely rare with only 37 built in 1969, well short of the numbers of Yenko Camaros and Chevelles. But with less weight than either -- even less than a 427 Corvette -- the L72 Yenko Nova was probably the fastest automobile Don Yenko ever offered.

1970 Chevelle SS

1970 saw the introduction of the most powerful Chevelle SS of all time. Responding to the lifting of GM's ban on engines larger than 400 cid in midsize cars, Chevrolet responded by dropping in a new 454 cubic engine into its Chevelle SS. The entry level 454 was known as the LS5 and packed 360bhp. The top engine choice was the LS6 version with 450bhp. The LS6 had a 800-cfm Holley four barrel on an aluminum manifold, 11.25:1 compression, solid lifters, four-bolt mains, forged steel crank and connecting rods, forged aluminum pistons, and deep-groove accessory pullies. No production engine ever had a higher factory horsepower rating. The standard Chevelle SS 396 continued with its 402 cid engines, although the 325bhp was dropped and the 350bhp version was now standard. Optional on both the 396 and 454 was a new cowl-induction hood, which had a rear facing flapper near the base of the windshield to feed air into the engine. The styling was new with a "vee" front end, functional hood pins, and five-spoke Rallye wheels. This was truly the pinnacle of the Chevelle SS performance.

Production: 53,599
Engines: L34 402 V8 350bhp@5200rpm, 415lb-ft@3400. 402 V8 375bhp@5600rpm, 415lb-ft@3600rpm. LS5 454 V8 360bhp@5400rpm, 500lb-ft@3200rpm. LS6 454 V8 450bhp@5600rpm, 500lb-ft@3600rpm.
Performance: LS6 454/450: 0-60 in 6.1 sec, 1/4 mile in 13.7 sec @ 103mph.

1970 Nova SS

The big change for 1970 was Chevrolet's decision to slightly modify the venerable 396 engine to meet new emission standards. The result was a slight enlargement of the big block to 402 cid although Chevrolet still refered to the engine as the "396" or the "Turbo Jet 400" to take advantage of its name recognition.

Production: 19,558
Engines: 350 V8 295 bhp. 402 V8 350 bhp. 402 V8 375 bhp.




As you can see, the Chevelle was the more popular 'muscle car' choice, cause it had the more options available.

I've always called the my Nova a baby Chevelle.


I'm not sure if I can help you anymore than that... other than they're two different cars.
