Challenger R/T vs Camaro SS: Which 1970 Muscle Car Should You Buy?

1970 was the year Dodge finally showed up to the pony car fight and the year Chevy completely rebuilt its entry. Fifty-six years later you can still buy either one, and the choice is a lot less obvious than the forum arguments suggest.

Two very different ideas of a pony car

The 1970 Challenger was Dodge’s first real pony car, built on the brand-new E-body it shared with the Plymouth Barracuda. Dodge stretched the wheelbase to 110 inches, 2 inches longer than the Cuda, and gave it a wider stance and more interior room than any Mustang or Camaro. It was a big, broad-shouldered car; a Challenger R/T with the 440 weighed around 3,800 pounds with a driver aboard. The engine bay was designed from the start to swallow the 426 Hemi, which tells you what Dodge cared about. The R/T package brought a standard 383 Magnum at 335 hp, with the 440 Magnum (375 hp), the 440 Six Pack (390 hp), and the 426 Hemi (425 hp) on the order sheet.

The 1970 Camaro was a clean-sheet second generation that arrived late, in February 1970, which is why you see it called a 1970-1/2. GM’s designers went for a long-hood, short-deck European look with a single-piece front end and no rear quarter windows. It was lighter than the Challenger by 200 to 300 pounds and sat on a 108-inch wheelbase. The SS package came with a 350 at 300 hp standard, and the big-block option was the 396, which actually displaced 402 cubic inches that year but kept the badge because Chevy knew the name sold. The L34 made 350 hp and the L78 made 375 hp. Despite what the internet says, there was no factory 454 Camaro in 1970; the LS6 showed up on the order sheet but never made it into production.

The same basic argument had already played out a year earlier between Ford and Chevy, and if you want the backstory, the Mach 1 versus Z/28 debate covers how the segment split into straight-line cars and handling cars. The Challenger and Camaro inherited those 2 personalities almost exactly.

Production numbers and why they matter today

Dodge built 83,032 Challengers for 1970, and about 19,938 of those were R/Ts across hardtop, SE, and convertible bodies. Of those, just 356 got the Hemi: 287 hardtops, 60 SE hardtops, and 9 convertibles. The 440 Six Pack went into roughly 2,035 R/Ts. The rest were 383s and 440 Magnums.

Chevy built 124,901 Camaros for the shortened 1970 model year, with about 12,476 of them wearing the SS package and 600 of those carrying the L78 396. Add in the 8,733 Z/28s and you have a car that outsold the Challenger by 50 percent despite being on sale for 5 fewer months.

What this means for you: there are simply more 1970 Camaros out there, and the second-gen body stayed in production through 1981, so the parts ecosystem is enormous. The Challenger ran only through 1974 and sold in smaller numbers every year, so the pool of donor cars and original parts is shallower, though the reproduction market has caught up dramatically in the past 15 years.

The insurance problem that killed them both

If you wonder why 1970 was the peak and not the start, blame the actuaries. By 1970 insurers were applying surcharges of 50 to 100 percent on cars with a horsepower-to-weight ratio above roughly 1 hp per 10 pounds, and some carriers refused to write policies on Hemi or 396-equipped cars for drivers under 25 at all. A 20-year-old buying a Challenger R/T in 1970 could easily pay $800 to $1,000 a year for insurance on a car that cost $3,266 to start. A Camaro SS 396 started around $3,500 with the SS and L78 options and faced the same math.

Sales told the story. Challenger production fell to 29,883 in 1971 and the R/T was gone after that year. Camaro SS numbers dropped to 8,377 in 1971 and the SS badge disappeared after 1972. The cars you are shopping for today exist in the numbers they do because the market shut the door on them almost immediately.

What they cost now: driver versus show car

The Challenger market is brutally stratified by engine. A driver-quality 383 R/T hardtop, meaning a solid, presentable car you can take to a cruise night without apologizing, runs about $55,000 to $75,000 in 2026. A 440 Magnum R/T in the same condition is $70,000 to $95,000. A 440 Six Pack car starts around $110,000 and a genuine, documented Hemi Challenger R/T is a $350,000 to $600,000 proposition, with convertibles at over $1 million. Concours-level restorations roughly double the driver numbers for the common engines. Beware of clones: a 318 Challenger that has been converted to R/T trim is a $35,000 car no matter what the fender badges say, and the fender tag and VIN will tell you the truth in about 30 seconds.

The Camaro is kinder to the wallet. A driver-quality 1970 SS 350 sits around $40,000 to $55,000, and an SS 396 with the L34 is $55,000 to $75,000. The L78 cars and the Z/28 push into the $80,000 to $110,000 band for excellent examples. There is no Hemi-equivalent ceiling here; the most expensive 1970 Camaro you can buy is a documented L78 SS or a show-quality Z/28, and either one will leave you with change from $150,000. A show-quality Camaro SS costs about what a driver-quality Challenger 440 does, which is worth sitting with for a minute.

Chevy’s history explains some of the gap. Among Chevy’s finest muscle cars the big money chases the Chevelle LS6 and the COPO cars, not the second-gen Camaro, so you are buying into a body style the collector market still treats as a driver. For a buyer that is a feature, not a bug.

Where each one rusts

Both cars are unibodies and both will try to dissolve in the same general areas, but each has its own habits. On the Challenger, the lower rear quarters behind the wheel openings and the trunk floor extensions go first, followed by the rear frame rails near the leaf spring front mounts and the cowl area under the windshield, which leaks into the floor pans on the driver’s side. The rear window channel traps water under the stainless trim and rots the package tray and the top of the quarters from the inside. Most of the Mopar unibody problem areas carry straight across the lineup, and the Charger rust guide is a useful checklist for a Challenger inspection even though it was written for the B-body. Check the torsion bar crossmember and the front frame rails where the K-member bolts up; repairs there are structural and expensive.

The 1970 Camaro’s weak points are the rear window channel and the rear quarters, where the lack of quarter windows means a huge panel with nothing but a thin seam at the top. The front subframe mounts and the floor pans under the carpet rot from inside out, and the lower front fenders behind the wheels pack up with debris. Cowl rust is common on cars that sat outside, and it will show up as a wet passenger footwell. The good news is that nearly every panel for a 1970 Camaro, including full quarters, floors, trunk pans, and complete subframes, is available new, and body shops have done so many of them that the labor is predictable. Challenger panels are available too, but the fit on some repro quarters is still inconsistent and the hourly rate for a shop that really knows E-bodies runs higher.

Driving them back to back

Get both cars on a 2-lane road and the differences are immediate. The Challenger feels like a smaller Charger: wide, planted, and softly sprung with torsion bars up front that soak up bumps well. The 440 pulls from idle with 480 lb-ft of torque and never feels stressed; it is a 14.0-second quarter-mile car in stock form and a genuinely comfortable 400-mile-a-day cruiser. The steering is slow and the car rolls into corners, but it is predictable. Interior room is a real advantage; a 6-foot-3 driver fits without folding.

The Camaro is tighter in every direction. The steering is quicker, the body is stiffer, and the lighter nose means it changes direction with intent instead of eventually. A 396 SS runs the quarter in the high 14s with the L34 and about 14.2 seconds with the L78, so it gives up a little to the 440 Challenger at the drag strip and makes it back on any road with a corner in it. The cabin is snug and the back seat is a formality. If you are the sort of owner who upgrades brakes, sway bars, and tires, the Camaro rewards every dollar; the aftermarket for second-gen handling parts is deeper than for any other muscle car short of a first-gen Camaro or Mustang.

The recommendation

Buy the Challenger R/T if you want presence, comfort, and the long-term appreciation curve. The E-body is one of the best-looking American cars of the era, it has room for people and luggage, and the 383 and 440 cars are still priced below where their rarity and reputation suggest they will end up. Skip the Hemi unless you have Hemi money and a Hemi-grade documentation habit; a 440 R/T delivers 90 percent of the experience for a fifth of the price. Budget $65,000 to $85,000 for a car you will not have to apologize for.

Buy the Camaro SS if you plan to drive the car hard and often, if you want to modify it without guilt, or if your budget caps out around $60,000. It is the better driver’s car, the cheaper car to own, and the easier car to fix on a Saturday. The 396 cars have the sound and the stripes; the SS 350 has the lower price and a chassis that does not care which engine is in front of it.

Both cars were killed by the same insurance tables within 2 years of launch, which is exactly why they feel so uncompromised now. The only real question left is whether you want the car that looks best parked or the one that feels best at 70 mph on a back road with the windows down.
