When someone is building a car and trying to make it a sleeper, they’ll attempt to make everything look, and sound, as mundane as possible; because you don’t want to reveal the car’s true nature. This three series BMW from New Mexico is the exact opposite of a sleeper, with a nasty blown V8 under the hood, and a rowdy camshaft, this car announces its intentions every time the owner starts the car.

Kyle and the guys from 1320 Video heard this nasty-sounding German sedan before they saw it, and were not expecting that sweet sound to come from a European luxury car. The owner gives some details about the car, explaining it has a 355 cubic inch small block Chevy under the hood, and admits the camshaft is just a bit large to optimize this combination. Behind the small block is a TH400 transmission setup with a transbrake, but the stock BMW rear end is limiting the use of the brake and hurts the elapsed time a bit, since the owner can’t push the car too hard when the tree drops.

The BMW is not all bark — it has some bite, as proven by the alleged 400 horsepower and over 700 foot pounds of torque on just 8 pounds of boost. With that much power, the boosted BMW has run a best of 11.50 at 119 mph in some intense southwestern heat, so there’s plenty left on the table. At the track, this BMW gave a GTR the scare of a lifetime, forcing the Nissan to run the BMW at the top end of the track. With a new rear end and some tweaking, this small block BMW could be a 10 second street sweeper!
