hen it comes to Chevrolet body styles, it’s hard to beat the flowing lines of the short-lived roofline officially known as the Sport Coupe in 1961 and 1962. Most people call these stylish coupes a “bubbletop” because of the rounded roof. Like most coupes of the ’60s, these cars were prone to rust issues, so you don’t see them as often as sedans. When you do, they’re often restored to stock or finished in restomod styling. Rarely, if ever, will you see one with a blower and injector hat sticking out of the hood and giant rear tires stuffed under the quarter-panels. We stopped in our tracks when we saw Todd Hann’s Pro Street 1961 Chevy Impala bubbletop at the Triple Crown of Rodding in Nashville last year.

Todd bought the car in 2001 for $800 and it was rough. The body was badly rusted, although the car was still able to move under its own power. By the time it was disassembled, there wasn’t a lot to show for his new project, but he had a vision for what this thing would become. He knew from day one that he wanted it to be black, and he wanted a killer big-block, but his original intentions leaned more toward the dragstrip. At some point in the 10-year build he shifted gears into the Pro Street setup, which led him even deeper into the project.







The engine combination features a Bowtie block and an Eagle rotating assembly that comes out to 540 ci. Brodix cylinder heads breathe deeply and work well with the BDS 8-71 blower. Todd used an eight-injector hat, and the electronic fuel injection is operated by a Holley HP system. It runs on 93-octane pump gas and handles all the abuse Todd can throw at it. Behind the blown big-block is a TH400 automatic transmission, equipped with a Gear Vendors overdrive to make the 4.56:1 rear gears much more street friendly.


Inside, Ted’s Trim did a great job working around the extensive rollcage. He installed factory-style carpet and wrapped the modern bucket seats in red leather with vintage-style inserts. He also modified the rear seat to work with the wheeltubs. Perhaps the most challenging part of the interior was the headliner, as the rollcage is tucked tightly to the roof. Todd used reproduction door panels from Ciadella Interiors and repurposed a 1965 Impala console to ride on top of the raised transmission tunnel. The dash is stock but features a selection of Auto Meter gauges in a carbon-fiber insert.
Todd and friends finished the car more than 10 years ago, but it still looks fresh and performs to Todd’s liking. He said he wants to keep it maintained and continue enjoying it because it’s exactly what he pictured in his head when the project started. It’s one of the only big tire bubbletops you’ll ever see, and it’s a fine example that proves that Pro Street will never die, because big tires, blown big-blocks, and parachutes continue to put a smile on gearheads’ faces around the world.
