6.4L Hemi V8 Engine - The Specs & Differences Between the Ram Trucks and SRT/Performance Versions

Need to make a correction: as many have stated, 2019 2500 and 3500 trucks used the ZF 8-speed automatic (8HP75R) with the 6.4. 4500 and 5500 still use the Aisin 6-speed.

I bought a brand new 392 Hemi long block from Mopar without MDS that was built Feb 2021 and can confirm that it does in fact come with the BGE engine block painted orange and T356 aluminum alloy cylinder heads and the new revised "hellcat" lifters. It’s a shame that it still has the same hyper-eutectic pistons and tightly gapped piston rings which means the engine cannot be safely boosted past 6-7 PSI without pulling and replacing the pistons.

[@demarcusbody9437]

Yeah bud that’s because the 392 is meant to be N/A it’s not meant to be boosted if u we’re looking for that u would get a Hellcat/6.2

[@alexm.4621]

@@demarcusbody9437 yeah but swapping in a 6.2 hemi into a SRT 392 hemi is not plug and play, it takes a lot more extra parts and a lot of extra work. Better to sell the 392 car and buy a factory Hellcat instead.

[@alexm.4621]

@@TheJMan1K from what I understand they are just revised lifters. Supposedly more durable than the previous part numbers used in pre 2017 MY engines. Those are the lifters that often end up failing and eating a cam lobe. There is no specific hellcat lifter though, should be the same lifter part number on all hemi engines including 5.7 6.4 and 6.2 from around 2017 an up. (Except automatic MDS equipped engines)

There's actually more differences. There's the performance 6.4 in the regular vehicles, there's the truck version... but the 6.4 Hemi in the 2500/3500 is not the same as the ones in the commercial Heavy Duty cab chassis of the 4500 & 5500 trucks. The HP/TQ is detuned less than the pickups & the redline is also lower, approx 4600rpm. There are other slight changes. But the 6.4 in the pickups is not the same as the 4500/5500's Those HD cab chassis trucks are detuned for longevity & Heavy loads & Heavy towing on a daily basis.

[@mercedesbenzisbest]

Not worth the time

[@sonsofliberty3081]

Let me help you out a little. The ram 392 has the same displacement as the car, but that's all. The car has a slightly bigger bore than stroke. The truck has whats called an underbore. The bore is larger than the stroke. The ram has completely forged internals and revs slower. The truck version is raited lower power than the gm, but will out pull it. The gm has a big bore and short stroke. All of your torque is made low with a long stroke motor. The cummins is built the same way the truck 392 is built. There are guys that use the truck 392 as a hotshot. They're pulling 15k+ all the time and getting over 400k miles out of them. The truck is built heavier than any other gas motor on the market. The truck also has an oil and transmission cooler. The drive shaft is way larger. If you want a truck to last a lifetime but gas powered, get the 2500 ram.

[@blueduster74]

Wrong. Same bore and stroke. Same crankshaft.

The Scat won out and I did buy one at end of Sept. 2020. But concerning the Hemi tick I wonder did I really make the right choice ? Did FCA make any changes to alleviate this tick, ruined cam issue in newer production engines ? I hate to think I made a $50K mistake.

[@johnnicpon5783]

I'm hoping to squeeze out at least 20-30 more Hp and torque if possible. I certainly feel like the truck needs it.

[@rigorousrangel6394]

Just like the Chevy 454s cars and trucks had the same engine but were 2 main bolts as opposed to 4 main.

[@brendanbuster]

Definitely want to fix that cam spec slide. The specs might be accurate, but the 2 cams shown were measured using different measurement methods. The car cam appears to be total duration (measured at "zero"-ish lift) and the truck cam appears to be the standard @ .050" lift measurement method. As you can see, it gives VERY different numbers and it's really misleading. They're likely much closer together, the truck cam is probably 265-270 degrees of duration measured the same way as the car cam.

Do the 6.4 truck variants have the active intake runners like the 392s?

[@TonyTheTruckGuy]

Good question but I think the truck does not have active runners. Honestly they probably use the same intake from the 5.7 which is why the truck version has the throttle body on top vs. the front and he said the runners on the truck were "tuned" for a specific RPM range instead of being variable like the car versions.

@@thedankgentlemann I can’t say with certainty since I have not personally tried, but it may be worth researching to see if anyone else has done. R/T life did a 6.4 car intake on his 5.7 Hemi but he had to get like an MSD box to control the runners. The truck intake MIGHT bolt right up. Not sure what kind of gains would be had though.
