Best of the Disco Era,‘70s Cars and Style at HOT ROD Power Tour 2017

HOT ROD Power Tour 2017 rolled from Arrowhead Stadium in Kansas City to Iowa Speedway and the Davenport fairgrounds, and the cars stealing the show belonged to the 1970s: the last high-compression muscle of the early decade and the blower-scooped, white-letter-tired street machines that followed. The decade Detroit almost gave up on turned out to be the crowd favorite. Read on to find out why ’70s survivors and tributes drew the tightest crowds on the tour.

Parking lots at HOT ROD Power Tour 2017 held the usual mix of restomods, late-model muscle, and survivors, but the cars drawing the tightest crowds at Arrowhead Stadium, Iowa Speedway, and the Davenport fairgrounds belonged to a decade Detroit would rather forget. Blowers poking through hoods, tunnel rams, raised-white-letter tires, gold valve covers, and paint loud enough to hear: the 1970s were back, both in the cars built during those years and in the ones dressed up to look like them. The decade began with the last real muscle and ended with the street machine, and the tour showed both ends. Why does a period once written off as the low point of American performance keep stealing the show?

From a Museum Parking Lot in 1995

HOT ROD Power Tour launched in May 1995 as an eight-day cruise from the Petersen Automotive Museum in Los Angeles to a Power Festival finale in Norwalk, Ohio, with any hot rod fan free to join at whatever stop was closest to home. The format was a dare as much as an event: drive a hot rod across the country and see who makes it. Nobody involved expected it to become the largest traveling car show in the world, but the come-one-come-all rule turned out to be the secret. By 2017, the tour was in its twenty-third year and the formula had barely changed.

The 2017 Route Through the Heartland

The 2017 tour kicked off at Arrowhead Stadium in Kansas City on Saturday, June 10, rolled to Iowa Speedway in Newton on Sunday, June 11, and then continued to the Mississippi Valley Fairgrounds in Davenport, Iowa. Each stop doubled as a full show for the local crowd, with the field made up of cars that had driven there that morning rather than arrived on trailers. Those first three venues, a football stadium, a race track, and a county fairground, gave the ’70s cars three very different backdrops in three days.

The Last Hurrah, 1970 to 1972

The early 1970s were the final years of unrestricted muscle car horsepower. Tightening smog regulations, rising insurance rates, and the shift to lower compression ratios after 1970 meant the big engines were on borrowed time, and enthusiasts who understood that bought the last of the high-compression cars while they could. That is why 1970 model-year cars in particular sit at the top of the decade’s hierarchy. On the tour, a 1970 Chevelle, Charger, or Cuda represents the peak of the factory muscle era, built just before the rules changed everything.

Bigger Cars, Bigger Presence

The decade also saw American cars grow in size and weight, bringing back a road-filling stature not seen since the late 1950s and early 1960s. Full-size coupes and personal luxury cars swelled, and even intermediates put on inches. To modern eyes that bulk reads as presence, and on a Power Tour parking lot a long-hood ’70s coupe with a big-block under it draws attention simply by occupying so much space. The cars that seemed excessive when new have aged into something imposing.

Blowers, Tunnel Rams, and Gold Valve Covers

While Detroit was losing horsepower, the street was gaining style. Superchargers through the hood, tunnel-ram intakes with dual carburetors, raised-white-letter tires, wild multicolor paint, and gold-anodized valve covers became the visual language of the late 1970s gearhead. Much of it was as much about looks as speed, but it defined the era’s aesthetic so completely that a modern car wearing those cues is instantly recognizable as a ’70s tribute. Power Tour 2017 had plenty of both: real survivors and new builds dressed in period costume.

The Dawn of the Street Machine

As factory performance faded, enthusiasts took matters into their own hands, and the street machine era was born. Instead of waiting for a manufacturer to offer horsepower, owners built it in the garage with aftermarket parts, bigger tires, and whatever engine they could fit. That do-it-yourself culture is the direct ancestor of today’s pro-touring and restomod movements, and it is a big part of why HOT ROD’s own identity is tied to the period. A ’70s street machine on the tour is not an outlier; it is the origin story.

Survivors Versus Tributes

The tour’s ’70s contingent splits into two camps. Survivors are cars built in the decade and still wearing period modifications, often with the same owner or family since new. Tributes are newer builds, sometimes on ’60s bodies, deliberately styled with ’70s cues. Both have value. Survivors are documents of what people actually did to their cars back then, while tributes prove the look still resonates with builders who were not alive to see it the first time. Walking the rows at Iowa Speedway, telling them apart was half the fun.

A Show With No Velvet Ropes

What sets Power Tour apart from a judged concours is that nobody needs an invitation. Show up with anything that runs and you are part of it, which is exactly why the field skews toward driver-quality cars rather than trailer queens. That openness matters even more for ’70s cars, many of which spent decades dismissed as unfashionable or underpowered before enthusiasts began appreciating what they represent. On the tour, a faded 1978 street machine gets the same parking spot as a fresh six-figure build.

Why the Decade Is Being Reappraised

For years the 1970s were treated as the dark age between the muscle era and the modern performance revival. That view has softened. Collectors have discovered that early-’70s cars deliver the same experience as their late-’60s counterparts at lower prices, and that late-’70s street machines carry a nostalgia all their own for people who grew up with them. The cars at Power Tour 2017 were evidence of that shift: owners were proud of them, crowds gathered around them, and the styling that once looked dated now looks like a deliberate choice.

The Decade Detroit Almost Gave Up On

The lead photo of a yellow-and-black machine parked in the sun captures what the ’70s contingent brought to the tour: color, attitude, and a refusal to apologize for the era. The decade began with the last true factory muscle and ended with owners building their own, and both halves rolled through Kansas City, Newton, and Davenport in June 2017. For anyone who still thinks of the 1970s as the years American performance died, a walk through that field would have been a useful correction.
