The 408 is one of the most popular small-block V-8 stroker combinations for Chevy, Ford, and Mopar. This time on Engine Masters presented by AMSOIL and supported by Earl’s Vapor Guard and Mr. Gasket, we take the first step to find out which engine dominates with a dyno duel between Mopar and Ford. The Dodge LA-engine-based 408 is a complete crate engine from BluePrint Engines—we just added an Edelbrock Performer RPM intake manifold, Holley carb, and MSD ignition. The Ford is a BluePrint Engines short-block, and we matched it to the Mopar with the same compression, cam, ignition, and carburetor. Edelbrock makes the only direct-replacement aluminum performance cylinder head currently available from the aftermarket for the Mopar, and that's what's on the BluePrint crate engine. To match that, we also used the Edelbrock Performer RPM cylinder heads on the Ford. Edelbrock makes several models for the Ford, and they are the same price for the 170cc and the 190cc heads, so we chose the bigger ones. And that's where opinions will run wild on this episode of Engine Masters.
