    The motor that should have been standard! Awesome work

    Posted by John Childress on Aug 5th 2023

    My 2011 300C 5.7 motor was at the end of the road. I went with the 6.4 long block and HHP did a fantastic installation. The car was ready weeks early and exactly as quoted.

    The engine is so smooth and powerful that I think all 300Cs should have come with this motor. Josh's tuning was perfect for my needs. It makes over 400 lb-ft of torque from an incredibly low 1500RPM all the way to 5000 - that is rear wheel! Even with the stock 5.7 exhaust, the motor puts out 426/425 at the rear wheels! Love the deletion of MDS - so much torque available at all speeds.

    Greg did a great job with the order and Josh tuned it like a true professional. I needed the low-end torque because stock the car has 2.65 granny gears! Imagine what an exhaust and 3.06 LSD can do!

    I fully recommend HHP!

    OEM factory built 6.4 Hemi long block engine at an amazing price. HHP shipped the engine in great time and it arrived in perfect condition. If you need a replacement engine, this is the best deal going!

    6.4 long block purchase

    Posted by Corey Peterson on Mar 2nd 2023

    Pros: Very quick shipping and well packaged! Long block included everything but oil pan and pick up tube, front timing cover and water pump, damper, intake and fuel system as well as valve covers.
    Cons: only one really and that is the hefty price to have it tuned to my 2011 300c as a swap from 5.7 to this 6.4 , $1200 -ouch!
