Nick and Vasilis chase 400 horsepower out of a freshly built Oldsmobile Rocket 350, comparing an Edelbrock intake against the factory cast iron piece on the dyno. Years later, viewers are still asking whether they actually hit the number — and debating whether a restrictive carburetor adapter plate held the engine back. Watch the full pull, then see what the comments say really happened.

A Nassau Blue 1966 Corvette roadster carrying the L72 427, factory-rated at 425 horsepower and 460 lb-ft of torque, headlines Episode 213 of V8TV’s Muscle Car of the Week. The car comes from The Brothers Collection, and viewers split over whether visible exhaust smoke points to needed engine work or whether the car is still a near-perfect judged example. See which side of that debate holds up.

A 1969 Camaro Pro Street build from jeprostreets swaps the usual Roots blower for a screw-type PSI supercharger, runs electronic fuel injection instead of a carburetor, and stacks nitrous on top for good measure. The builder answers technical questions directly in the comments, but hasn’t yet shown the car making a pull. See the setup that has viewers asking about tuning, not just horsepower.

A single customer commissioned Hennessey Performance to build out both a Camaro Z/28 and a Camaro ZL1, combined for roughly 1,650 horsepower, then arranged access to a private airport runway to settle which one was faster. It is a rare look at two very different performance philosophies from the same brand going head to head with real stakes. Even a self-described Mustang fan in the comments couldn’t argue with the result. Watch to see which Camaro wins.

Only ten 1966 Plymouth Belvedere II convertibles left the factory with a 426 Hemi, six of those with automatics, and just one in the color code 661 Metallic Mauve — the car in this episode, restored with its original numbers-matching driveline intact. Commenters can’t agree if the color is mauve or purple, but they agree on one thing: this Hemi was built to be feared, not casually enjoyed. What actually makes a car the rarest piece in a collection already built around rare Mopars?

A 1969 Camaro with 680 horsepower, a full custom interior, one-off wheels, and McLaren paint looks like a horsepower story. It is not. The Gen V LT1 is rated around 455 horsepower from the factory, so reaching 680 means real work, and making a 1969 unibody survive it means replacing almost everything underneath. Read on to find out where the money in a build like this actually goes, and why the power figure is the least useful thing about it.

1958 wasn’t just a facelift year for the Ford Fairlane, it was the debut of the FE engine family that would go on to define Ford performance for two decades. This particular car runs the mid-pack 332 V8, one of the two new FE engines, slotting above the carryover 292 Y-block base engine and below the range-topping 352 Interceptor. Here’s what made that engine lineup, and the reworked body it arrived in, worth remembering.

Two father-and-son 1957 Chevys, twin-turbocharged and pushing over 6,000 combined horsepower, went head to head across all five brutal days of Drag Week 2014. The newer, lighter build known as ‘The Evil Twin’ edged out its heavier stablemate ‘The Beast’ despite similar power. Watch to see exactly how much an 800-pound difference mattered.

A photo of a full-size 1962 Pontiac Catalina lifting its front wheels off the ground has circulated through drag racing circles for over sixty years, and the 405-horsepower 421 Super Duty engine behind that wheelie was no accident. Pontiac built it to win against rivals throwing bigger money at the strip. Read on to find out how a corporate racing ban nearly erased the whole program within a year.

A 1966 Chevrolet Bel Air was never meant to be anything more than dependable, affordable transportation, Chevrolet’s plain-Jane offering that sat below the flashier Impala. Somewhere along the way, one particular example ended up wearing a rear-mounted turbo setup chasing four-digit horsepower numbers nobody in Detroit could have imagined in 1966. Read on to find out what it takes to turn a sensible family sedan into a four-digit-horsepower monster.
