Generally speaking it is a beefed-up version of the 6.4 block used in 3/4- and 1-ton trucks.

Hell yeah that's a pretty burly combo, IMO it's begging for a tunnel ram! Intake is already too tall for a hood right? Lol...

Nice, any other mods (cam, heads, internals)? What kind of times are you running with that setup?

Makes complete sense for a more race-oriented setup. I'd go the same route if I was building a street/strip car. I know how to tune both carbs and EFI, I have more experience with carbs but taught myself how to tune a bit on my Buick (supercharged 3800 V6) and there are pros and cons to each...

My cousin was visiting the area from overseas last week and was staying in Charlotte. He wanted to try some Southern BBQ so we met about halfway in Columbia, SC. I decided to drive my Duster to give him a ride in it and show how much it had progressed over the last 8 years or so since I had...

I think for it to tick for just the first 30 seconds shouldn't be an issue, I wouldn't be worried about that. If it continues ticking especially after it's warmed up then it's a problem. If you want to do a cam+lifter swap anyway that's fine but if it's only because you think a lobe/lifter is...

That's what I did too but it seems the site now automatically detects media links...

I don't remember for sure, been a while since I saw it but here's a link to the video: Looks like from the thumbnail it actually went from around 20 to 40 psi.

So the Reignited Cycle and Auto guy on YT did a test on a high-mileage 5.7L where he installed a HV Hellcat oil pump and it bumped the hot idle oil pressure up from something like 10-15 psi to 25+. He reasons that should help with lifter failure due to extended idling. I still haven't gotten...

That makes sense. I've never been a big believer in the extended oil changes for modern cars, I do my mom's 2014 Chrysler 300 V-6 every 5k miles but even that feels like it's pushing it just a tad. I always use full synthetic in her car for that reason. Almost makes me want to get a...

What about factory manual-trans setups with the MDS already deleted? They have non-MDS lifters... and wouldn't an oil volume issue (if the pump is too small) show up as lower-than-normal pressure at lower RPMs?

Ok fair enough. I do partly agree it's always shitty when a company decides to screw over the customer like that because it's cheaper. Myself I'm only "loyal" mostly to classic Mopars just in the sense they're my favorite type of car to mess with but when it comes to late models I don't think...

Agree on the manual trans and pushrod theory, I have a 2014 5.7L from a Ram 1500 with 137k miles and bad cam lobe/lifter that was replaced under warranty. When removing the rockers it felt like the lifters had barely any preload, certainly less than what I'm used to on a LA/Magnum. I intend to...

Guys you're getting ahead of yourselves lol just watch the video. @408 swinger he explains in the video that the oil passages from each solenoid go to both the MDS and non-MDS lifters in that set since each solenoid goes to a set of 4 lifters and the MDS cylinders are staggered. It could very...

I stumbled across this video and after watching it I think this guy has come as close to identifying the issue (and fix) as anyone. He worked as a Dodge/Chrysler/Jeep tech for years so he has tons of experience with these engines. He did mention Uncle Tony's video (without any name-dropping)...

Very nice, would you mind posting pics of the issues you described like the steering box clearance, remote oil filter setup and steering column mods? Your build is almost exactly the same as I want to do for my future G3 swap except I hope to have a T-56 already in the car behind my current 5.9...

Oh well if FCA says it then, hmmm... lol. I thought we had at least one member on here who tunes G3 Hemis I'm sure they would know? I'm glad I found this thread because it means the MP kit most likely won't work for my Hemi. 2014 5.7 out of a truck and it'll have a 6.4 SRT camshaft and...

How did you find that out? From the little I've researched the only differences between car and truck Hemis are the intake/exhaust manifolds, front accessory drive and camshaft specs. Nothing that couldn't be "tuned out" with the unlocked car PCM I would think?

I'm curious about the QA1 also, I'd really like to keep my torsion bars for my G3 swap.

What about using an aftermarket intake manifold like the Prefix/Arrow single-plane? I picked up a complete 2014 5.7 out of a truck with a bad cam lobe and lifter and only 137k miles for $600... for the cost of stepping up to a 6.4 I could buy conversion headers, aftermarket intake manifold and...

Lol I hear you Tim, this is a long-term project that won't get going for quite a while and I plan to drop in a craigslist 5.9 Magnum with a nice hyd. roller cam and mildly ported Mag heads from my old 360 for the time being. Dang that's pretty smart, how long of a time-frame are we talking...

This makes me giddy for the 5.7 VVT swap in my Duster... with the Eagle heads and 6.4 non-MDS cam I think it should put down 400 at the wheels seeing how yours did. Also did you modify the transmission so you could powershift it like that? I thought that kind of thing only worked on old-school...

Wouldn't need to be welded in that way either, at least not completely since the force is going that direction...

That sucks, my '93 Jeep Cherokee is a 5-speed manual and never had a clutch safety switch. I always start it in neutral with my foot off the clutch, helps save the thrust bearing (it has 240k miles). Also nice to have for off-roading or some other emergency if something happens to the engine...

I would if they weren't $700...

Dang that sucks, so it's a matter of "when" not "if"... When I get the camshaft out of this engine I'm gonna look for that "flaking" of the lobes. Anyway it's not like I'm going to put another 50k miles on this thing once it's in my Duster lol, that would take a decade or more.

OK so the lifters aren't the problem... can this be prevented by using high-quality oil? Would there be any benefit to running higher-end stuff like Brad Penn or is something like Valvoline Synthetic enough? Guess I should look at what the factory recommends...

I'm curious too, I know I mentioned them in your thread but surfing around on the Web I can't find anyone who's actually used them, everyone seems to just use stock replacements... which I find a bit odd knowing lifter failures are fairly common on these engines?

So what does everyone think about having the heads cleaned up and a valve job done? I've heard the earlier Hemis had valve seat failures, what did they do to fix them on the newer ones? Will I need new valve seats if I want a valve job? Or is it even worth it on a 140k-mile engine in the...

Just did a quick search, people on other forums are saying if it shuts off when it gets hot either the ECU is bad or a sensor is bad. Since it starts running when you cool off the ECU itself it's probably bad. I would try hitting up some of the other Gen 3 Hemi tuners such as Modern Muscle...
