ATK Remanufactured Engines

If you’re restoring a classic car, muscle car or hot rod, it’s a good bet that the motor in it is going to be pretty tired — if it’s still working at all. ATK Engines has been a performance engine builder since 1946 and has an engine combination that will get your project car roaring again. Rebuilding an engine is fun for some, but exhausting and time-consuming for many others. By choosing ATK, you can get everything from a partial build to a drop-in powerplant that’s ready to hit the road or the track.
