Do you think that there is any chance that IHRA will allow this one? Could be pretty good around 400 factored HP. Fun for sure especially with a stick.

Mopar Performance revives Six-Pack small-block

The triple-carbed Mopar engine is a mainstay of the muscle car genre, and one that makes fans of all makes and models take notice.

Back in the day, Chrysler offered the three-deuce arrangement only on small-block engines in a limited run of Challenger T/A and ?Cuda AAR models, which were really only offered to the public to homologate the package for Trans-Am racing.

Now Mopar Performance has combined the trio of Holleys with a small-block and added the benefit of more cubes. The 410 Magnum Six-Pack crate engine is based on a brand-new block, which MP claims is a 340 piece rather than the late-model Magnum type most of its recent crates have used. The block is stuffed with a 4.00-inch cast stroker crank, which, when combined with the 4.040-inch bores, creates 410 cubic inches.

The cylinder heads are cast-iron Magnum R/T ?big-valve? assemblies, though they utilize the Chrysler LA-series small-block intake bolt pattern, allowing the aluminum manifold to bolt right up. The compression ratio is a pump-gas compatible 9.7:1 and the camshaft is hydraulic, with 248 duration at .050 and .508-inch lift. The engine comes with an eight-quart center-sump oil pan and Mopar Performance cast aluminum finned rocker covers, but you?ll have to round up a set of carbs yourself (MP has them, too).

Rated for 450 horsepower and 475-lbs.ft. of torque, the Six-Pack crate small-block makes a perfect powerplant for the street/strip Mopar
