You're just now noticing this?

Good morning, and welcome to 2006

The factory hasn't made any cheap, brand new 5.9s since 2002. MP used up everything the factory made for a few years, sold many $6000 dollar crate motors based on factory engines and when they were gone that was that, which was circa '06.

The foundation for the higher priced engines is a brand new
$3000 dollar race block, Scat/K1/Diamond forged lower end components, Edelbrock heads (in the case of the 440, a special casting), and they're built by Gary Stanton Racing Engines.

Please feel free to try to duplicate any of them with all brand new parts, paying a professional to machine, build, dyno test and warrantee it, and let us know how that works out

Meanwhile...if you want a lower priced crate motor, try a brand new 425HP 6.1 HEMI for $6440 retail. Anywhere a small block will fit, a 6.1 Hemi will fit. Ask Jegs to tell you all about P5155437. The factory doesn't make those anymore either, they switched to 6.4 so get one while they're hot.
