1971

The '71 year saw only modest styling changes. Inside, the SS model got new "European symbol knobs", and a four-spoke steering wheel became optional. 1971 Monte Carlo also saw the addition of a stand-up hood ornament. Mechanically, it was largely unchanged, although the small-block Turbo-Fire 400 two-barrel engine was dropped. Other engines had compression ratios lowered to allow the use of regular leaded, low-lead, or unleaded gasoline, per a GM corporate edict. Engine ratings fell to 245 hp (183 kW) for the base Turbo-Fire 350 CID (5.7 L) two-barrel, 270 hp (201 kW) for the Turbo-Fire 350-4V, and 300 hp (224 kW) for the Turbo-Jet 400. The SS 454 engine was actually raised to a nominal 365 gross hp (272 kW) despite the reduction in compression ratio. This increase in horsepower was a result of the 454 engine using the more aggressive camshaft from the 390 hp 454 used in the 1970 Chevrolet Corvette and full-sized sedans.

Chevrolet listed both gross and SAE net horsepower figures in 1971 with the impending change to SAE net ratings in 1972. The ratings compared as follows:

There has been no documented case of a 1971 Monte Carlo SS car with the 425 hp (317 kW) LS-6 version of the 454, with solid valve lifters and a longer-duration camshaft, previously found in the 1970 Chevelle SS 454 (where it was rated at 450 hp (336 kW)); however, they did come with an LS5 454. The Turbo Hydramatic officially remained the only transmission for the SS, but a heavy-duty clutch option on the order form suggests that it may have been possible to special-order a 454 LS-6 with a four-speed manual transmission (the four-speed wasn't listed officially as an "SS" option but was available as an RPO in regular Monte Carlos with the 350 and 400 engines). The exact number of such combinations, if any, is unknown since they were not officially listed as factory options but possibly assembled through Chevrolet's "Central Office Production Order" (COPO) process that had previously made possible model/engine combinations not officially available. However, there has never been a documented case of such a combination. Chevrolet records indicate that the factory only installed the LS-6 installations in Corvettes that year.

The SS 454 package would be discontinued after this year following production of only 1,919 units, but the 454 CID V8 engine would remain optional in Monte Carlos through 1975. The reason given for discontinuing the SS was that the Monte Carlo was marketed as a luxury vehicle instead of a muscle car. The SS nameplate would be resurrected 12 years later. Yet, at the same time that the Monte Carlo SS was judged a failure in the marketplace and discontinued, the Monte's reputation as a performance car on the race track was gaining strength because Ford and Chrysler were ending their factory-backed racing support due to declining muscle car sales and the need to divert dollars to meet costly Federal safety and emission regulations (General Motors' official policy had prohibited factory racing efforts since 1963). As factory support ended at Ford and Chrysler, the stock-car racing mantle switched to independent teams and sponsors, who overwhelmingly chose Chevrolets over Ford and Chrysler products due to Chevy's much greater availability and affordability of over-the-counter racing parts through the Chevy dealer network. And the Monte Carlo was considered the best suited Chevrolet model for stock car racing by most NASCAR teams due to its 116 in (2,900 mm) wheelbase (only one inch above NASCAR's minimum requirements at that time, the Chevelle 2-doors had a shorter 112-inch wheelbase) and long-hood design which placed the engine further back in the chassis than most other vehicles for better weight traction. Thus the Monte Carlo became Chevy's standard-bearer for NASCAR from 1971 to 1989.

Like its 1970 predecessor, production of the 1971 Monte Carlo also got off to a slow start due to a labor strike, this time a 67-day corporate-wide walkout that coincided with the introduction of the 1971 models in September, 1970, leaving dealerships with only a small shipment of 1971 models (built before the strike) in stock until the strike was settled in mid-November, 1970 and then slow-going in reaching normal production levels until around January 1, 1971. Model-year production ended at 128,600 including the 1,919 SS models. AM/FM stereo radios with 8-track tape players were optional.[5]


that sounding right to u from the wiki web site..
