Q & A

What's in the Box

This Mopar V8 swap kit allows you to install 340-360 motors in the ’67-’72 A body Mopars such as Cuda, Dart, Demon, Duster, Scamp, and Valiant cars that originally had a Slant-6. 

  • 1967-72 Dart, Duster, Valiant, etc. originally equipped with a Slant 6. 

Note: The mounts can be shifted somewhat front-to-back (to allow the transmission mount to align with the transmission mount crossmember) and thus get the engine in the “stock” position. Exhaust clearance can be tricky. It is recommended to use the close-fit, factory V8 exhaust manifolds or Block-Hugger style headers to ease those issues. Clearances to other areas can be close, but can be dealt with by sourcing original V8-specific components, “massaging” the trouble areas, or acquiring aftermarket equivalents for just such a conversion. Most customers have minimal difficulty when using V8s from passenger applications.
