Description

The MMX 454 HEMI Stroker Engine is a performance short block designed to maximize naturally aspirated power for 6.4L HEMI platforms. Featuring a 4.250-inch stroke crankshaft, 6.125-inch connecting rods, and a 4.125-inch bore, this unit offers compression ratios ranging from 10.5:1 to 11.5:1.

Built exclusively from 2011-2017 SRT 6.4 block cores, this engine requires specific components for optimal performance. MMX recommends the use of a HI-RAM intake manifold to achieve its rated power potential.
