New-tech 6.1L Hemi looks right at home in this E-Body's engine bay. Street & Performance programmed the engine's computer, while Henry County Rods made sure the wiring was trouble-free (and installed cleanly).
Art Morrison four-link rear suspension houses a Mopar 8-3/4-inch rearend while replacing stock springs. Mufflers are Dynomax units, at aft ends of 3-inch exhaust pipes.
CNC porting the aluminum twin-plug heads and extrude honing the long-runner intake likely boosts this Hemi's horsepower peak past 425. Battery was relocated to the trunk for handling/underhood clean-up reasons.
If you like 21st century powertrain and chassis tech inside a classic 20th century E-Body, you're our kind of Dodge Material!
