  4. Engine / Intake / Exhaust / Performance
    For some reason, I'm having trouble finding the stock 6.4L cam specifications. I've found some literature on duration listing 286/288, but I assume that's at 0". Lift is listed as 0.577" and 0.537". Can anyone tell me the duration at 0.050" and the LSA? I'd like to compare to other...
  5. The SRT-8 (6.1L and 6.4L V8)
    Hi. I've been away from the Forums for so long, I might as well be a newb... That being said, how many kms/miles do you get from a tank in a 6.4L? Let's say it's 90% highway.
  6. Engine / Intake / Exhaust / Performance
    At Livernois Motorsports we strive to be the best and always do extensive research on all of our builds and make sure each vehicle has the capability to withstand the power thrown at them. In case you did not know the 6.4L Hemi has a very weak rod and piston that are not able to withstand boost...
  7. Charger Discussion (3rd Gen - 2015 +)
    So I would like to get a better grasp on the real issues with supercharging a scatpack. Now i know that it has a cast rotating assembly which is the weak link, but at low boost (5-7psi) some survive and some do not. I come from a turbo subaru background when it comes to boost, and correct me...

    SOLD - 392/6.4L OEM Crankshaft Description: OEM Crank from 392 SRT8. I incorrectly purchased thinking it was for a 6.1L. I had it polished at a machine shop and they confirmed it within spec for standard bearings. A couple of teeth on the reluctor wheel are a bit scrapped (see last pic) $OLD...

    Go Mango. In pics it always looks bright, but I just can't get a good read on it and have never seen it in person. What are your thoughts? Love it or too flashy? The 6.4L gets enough attention as it is, is Mango adding fuel to that fire? Just curious everyone's opinions on such a rare color.
  12. Engine / Intake / Exhaust / Performance
    So I am going to be installing a 6.1L intake manifold on my 6.4L Hellcat Shortblock (Hellcat bare block, built with 392 crank and forged rods/pistons) with Edelbrock heads. What intake manifold gaskets and bolts should I expect to use? Stock 6.4L gear? Stock 6.1L gear?
  13. Engine / Intake / Exhaust / Performance
    So how well does the 6.4L intake manifold deal with boost? Does have any major restrictions? I have been tossing around the idea of installing a 6.1L intake but then realized the throttle body isn't compatible, I could swap in a 6.1L based version, which is smaller, and buy a harness adapter...
  14. Engine / Intake / Exhaust / Performance
    So would love to hear opinions on the best route to go. I am in between a lot of choices between a hellcat short block, a stroker, a factory dimension forged, drop ins, etc etc. I ordered a Hellion twin 62mm setup. Goal is around 900whp to run some mid to high 9's. My main questions are is...
  15. Power Adders
    Anyone know at what point I should be worried about cracking or blowing up the factory plastic intake manifold on the 6.4L? Seems like if it is an issue I don't have many options but the Edelbrock...any advice appreciate it. I assume with the twin 62mm turbos I will be running I will need...

    So if you go on Hellion's site, they only list kits for the 6.1L based vehicles, but when I scour through old posts there are multiple mentions of a 6.4L kit and links to Hellion's website that no longer work. Tells me maybe they discontinued making it for the 6.4L? Then I found the below...
  17. Engine / Intake / Exhaust / Performance
    Tossing around a lot of ideas on how to build my 6.4L 300, and I’m struggling with a final decision. I would really love to strap on the Hellcat 4.5L Whipple, but not sure what parts can be reused or what will line up. How do the heads compare bolt pattern wise? do the 6.4L heads even bolt...
