22. Volvo 240 Wagon
The big and boxy Volvo Wagon is the perfect candidate for a V8 swap. Obviously, it has a lot of space to put any engine inside. It comes with rear-wheel drive and Volvo built it like a tank. And that means it can endure all the additional power and torque.
But best of all, the 240 Wagon makes the perfect sleeper. After all, nobody would expect an old, clunky Volvo wagon to accelerate like a new Corvette.
