For 1971, performance began to be emphasized less, and when it was, it was aimed at a slightly more luxurious market. Even the first of the economy muscle cars such as Road Runners now had power amenities as standard equipment. However, the economy-minded performance enthusiast was still out there, and that guy had a couple extra bucks to spend to score something hotter than grandma’s stovebolt-six Malibu.
For 1971, Chevrolet was well on the path of neutering the Chevelle. Even the front fascia was emulating the wildly popular Monte Carlo that had been introduced the year before. The Chevelle SS 396 and SS 454 gave way to a unified Chevelle SS — regardless if there was a 350, 402, or the last remaining tune of 454 powering it. The availability of a 350 was for those who wanted an SS with less of a hit from their insurance. But even with one of the 350 mills under the hood, it was still a pricey car — even before adding options.
Get heavy
Mid-year in 1971, Chevrolet introduced the Heavy Chevy. It was an economical yet sporty looking fill-in between an entry-level Chevelle and an SS. Available only as a 2-door “Sport Coupe” hard top, the most pronounced feature of this YF3 code package was bold tape stripes and “HEAVY CHEVY” lettering on the front fenders, hood and deck lid in black or white vinyl.
Interestingly, at introduction, if equipped with a vinyl roof or a black or white painted roof option, the tape stripes were deleted. Also in the basic package was a domed hood with front locking pins (essentially a Cowl Induction look-alike), black front grille without a Bowtie, and 14-by-6-inch square-slot rally wheels with chrome cap and lug nuts but without trim rings (think GTO Judge).
The base engine was the 200-hp, 2-barrel-fed, 307-ci V8. However, both flavors of 350 (in 2-barrel 245-hp and 4-barrel 270-hp configuration) and even the 300-hp 402-ci Mark IV big block were optional. The 454 was reserved exclusively for the SS.
In addition to the standard “three on the tree,” all other transmission options were available respective to the chosen engine — with all automatics being column-shift only. Priced at $2,804, a Heavy Chevy undercut an entry-level SS by $639 — back when you had to have had a pretty good job to make that kind of coin in a month.
Base-level fun
It’s been reported by some less-than-reliable sources that a Malibu Sport coupe could also be ordered with the Heavy Chevy package. However, sales literature and dealer ordering documentation state that the Heavy Chevy was a package for the basic Sport Coupe rather than the Malibu. Indeed, the 1972 dealership brochure emphatically states that the Heavy Chevy was the performance-model base Chevelle, while the SS was the performance Malibu.
The brochure also states that the base-level and Heavy Chevy interior choices were identical — bench seat only in one of four color or material combinations with color-matched rubber floor, while the Malibu and SS choices got a deluxe bench seat or buckets with carpeting. Finally, the YF3 package was a “restricted option,” in that dealers could only order the set groupings of available options and trim. So unless verifiable original documentation can be presented with it, any Heavy Chevy claiming to be a “COPO” or “specially ordered” with non-package options or colors is fantasy.
The Heavy Chevy was not carried over to the all-new 1973 A-body Chevelle, Malibu and Laguna series. The SS was delegated as an option package and the Laguna offered an S-3 luxury-sport package as your quasi-performance choices. At least a 454 was still on the approved options list — even if it was in nearly the same tune as those fitted to one-ton trucks.
Still cheap — if you can find one
Today, a Heavy Chevy is rarely encountered. With only 6,727 built in 1971 and 9,503 for 1972, that’s understandable. Only 30 of them are in the current YF3 registry. Yet when they surface, they don’t pull the money of even a far more common small-block-powered SS. Then again, in the years they were just used cars, a lot of them probably gained SS badges. Especially so when muscle car interest and pricing began to rocket — and knowledge of what’s correct and not wasn’t as readily available.
Thanks to corporate parts sharing (the wheels were also a staple of second-gen Camaros of the 1970s), keeping one alive is a non-issue. Even the graphics are now available in repop land. And as such, there is now also the probability of a fakey-doo being made out of Aunt Flossie’s 6-cylinder Sport Coupe.
With fewer top-tier muscle cars hitting the streets today, we’ve already started to see an uptick in values for second-tier sporty cars like the Heavy Chevy. Also helping is the marked rise in interest and prices of smog-era ’70s cars and trucks in general. As such, they should go nowhere but up in price at a higher rate than primary-tier muscle cars in the foreseeable future.
