A nearly 60-year-old Oldsmobile small-block gets strapped to a dyno to settle an old argument among die-hard owners. The W-31’s spec sheet borrowed valves straight from Oldsmobile’s own 455 big-block — yet it wore a “350” badge plain enough that almost nobody shopping a showroom floor in 1969 took it seriously.
The ‘Unicorn C5’ twin-turbo Corvette already put down 980 horsepower on the dyno once, then spent three months getting torn apart, rebuilt, and delayed by broken parts before the team at 1320video could chase the number again. Tucking a pair of turbochargers into a C5’s notoriously tight engine bay is never simple, and this build proves it. The team found a few more horsepower along the way and plans to push it further still.
A 1967 Mustang Fastback with a dyno-verified 370-horsepower 302 sounds like a straightforward resto-mod until you realize Ford did not build a 302 until 1968. That single detail explains the entire philosophy behind this build, and it raises the question every resto-mod eventually has to answer: at what point does a modernized classic stop being the car it started as? Here is what the 1967 Fastback platform gives a builder, and what it asks in return.
This Mustang was deep into a 150mph dyno pull when a tire let go, turning a routine test into one of 1320video’s most-watched clips. Viewers point out the irony immediately: a dyno is supposed to be the one place a car can hit that speed with zero risk, and this one still found a way to go wrong. Watch to see exactly how violent a tire failure looks at triple-digit speed.
