@@getyomoneyup I BELIEVE THAT THAT WAS ITS LIMIT. I GOT GREEDY AND TURNED THE BOOST UP TO 15LBS AND KILLED THE STOCK VALVE SPRINGS. I SHOULD'VE TOOK IT LIGHT AND BUMPED IT UP TO 13.5-14LBS OF BOOST 1ST. I PROBABLY WOULD'VE HEARD THE SPRINGS START TO STRESS IF I DID. I ALSO HAD AN MDS DELETE, 6.1 CAM, AND 6.4 LIFTERS.(THE STOCK 6.4 LIFTERS ARE THE EXACT SAME ONES THAT ARE IN THE HELLCAT. DON'T OVER PAY JUST BECAUSE A SELLER IS SELLING THEM AS SOMETHING SPECIAL.)
@@patrickstrauss9800 that’s only if you’re going for high numbers you can literally slap a supercharger on an run low boost (under 6psi) safely and be putting down about 500 whp
Man you have more diverse, overall high performance knowledge than any other RU-vidr that I've seen. I love how practical and funny your videos are. You're informative and entertaining which is the best combo for any content creator.
5.7 in general is a good motor. The crappy part about them is they come neutered from the factory. Simple Ported Intake Manifold, Headers and Exhaust, Drop in filter, and a tune and you got a nice setup. If you wanna get frisky, drop in a 3.09 gear with a tire and you straight
Get a 6.1. The 5.7 is a balance between power and economy. None of the internal parts are performance oriented, so you gotta swap EVERYTHING out to make power. Heads, cam, headers, intake, etc. It's all gotta be upgraded for airflow. The 6.1 was designed to kick ass. Everything in that motor was made for airflow. The heads, cam, and intake manifold are excellent out of the box. It even comes with stock shorty headers. Mine is a 100% stock motor with a blower on it. It makes 5.5psi and 507whp. I gained over 150whp from less than 6 pounds of boost. A stock 5.7 will never see those gains from 5 pounds of boost. You'd be lucky to get 100hp from that cuz the airflow is so bad in the motor.
@@just_a5.7 i'm not heavily built. I have a stock motor and a blower thats not even running 6psi right now. Of course i'd get walked by a fully built 5.7. That kind of proves my point actually. That you need to build the shit out of a 5.7 to match a 6.1 with a blower lol.
@@jacobdyer2291the older 5.7s takeoff is what kill the bigger hemis and the only reason i know is because i was undefeated racing those on mine. My hardest race was an old ass impala donk wit a 383 stroker turboed and supercharged. That bih jumped in the air like vin diesel car did on the movie and i barely beat it too 😂😂😂
I'm getting to revere the knowledge and research that you put in the issues that you discuss on your channel about different cars and motor set up. I would love to see you do a few shorts about what you would do with the transmission set ups that you would like to run in your ride to get the solid , ground pounding, really reliable, heavy duty daily driver tranny that you would put behind your own say Challenger 08 R/T with the modification that you so well describe in this short video. Thanks again for your time and effort with your shorts that are enjoyable and informative at the same time. Great evening to you and your family, Guru!
@@gullahgeechee2699 I saw that video of the tree crash, that wasn't a modified 5.7 hemi.( It didn't have the power !). When I say potential, I'm talking about modified )
Yup Lotta potential, but I've seen a few bone stock early 5.7 hemi drop a valve seat at the first whiff of slightly overheating. If you are gonna build one, ping the valve seats
I just got my eagle heads, exhaust manifolds from a 6.1. hell cat push rods, springs, and lifters, 90mm throttle body and I'm gonna true dual my exhaust. And your vid pops up 😭🤣🤣. I always listen and fallow . Great vid
Good price for that 300C - I sold my 06 last year with almost 190k for $2,800 with a little bit of body damage so yours sounds like it was a way better deal lol.
@@Stressless2023These cars aren’t even worth 4k, got my 300c 06 for 4600 only 100k miles. The owners never changed the transmission fluid and now I gotta sell it 😂😂
Thank you cuz you really can turn an R/T into a Hellcat. People hate on the 345s but don’t know you can easily tune them to be better than Scat Packs and I plan on keeping my R/T and mod it over time to make Hellcat power
The gen 3 hemi is from 03- to the present. All the 5.7/6.1/6.4/6.2 are all based off the gen 3 platform. The most slept on of them all is the 6.1. It’s a great motor from the start, and has a lot of potential. Plus, none of the lifter issues/ valve seat issues like the 5.7. The 5.7 is definitely the underdog of them all, but the most slept on is the 6.1.
The 5.7 is the benchmark, but that engine is built for longevity, reliability, moderate performance, but a hell of a highway cruiser in which this engine is better suited for cause HEMIs hate city driving.
I’ve always had this idea in my head. Mildly tuned 5.7 with the new Trx drive train would be a recipe for fun since ur not gonna pass the 400 hp mark your axles, transfer case and transmission aré overbuilt and would never be push to the limit 4wd donuts 🍩 would look amazing 🤩
Well my brother, I had a 2006 R/T dodge magnum. I kept the oil changes up to date and kept all the maintenance together. I blown 2 motors in a 3 year span. Blown head gasket and the other time a blown heater coil I believe. So off experience, The car didn’t like me! But keep doing good work bro, giving good info and positive energy!✊🏾
I have the same car. Overheated on me twice now for external reasons. 1st time fans quit, 2nd time the rad had a leak. After both of those it still has no head gasket issues and I drive it everyday. 180+k on it.
@@younkinjames8571 I've had my 2014 Dodge Charger RT off a salvage auction at 40k miles I just hit 80k miles without a single issue I'm pretty sure she's gonna hit 150k no problem
I’m subbing to you. FINALLY someone else with a brain is saying the same shit I tell any mf that’ll listen. Yes, the 6.4 is better STOCK for stock. BUT, you have to do hella shit to it to make it ridiculously faster. The 5.7’s have been around for ages now, they’re just choked out coming off the assembly lines. Because they’ve been around so long they have better mod support. There’s RU-vidrs with R/T’s that have made some CRAZY power with probably half the mods than what a 6.4 would need to make the same insane #’s! Just my 2 cents…
@@jmhellison I have a 2018 Charger R/T. I wanted the extra 2 doors. It totally depends on what your preference is. The ChalIenger is like 300 lbs lighter though. I just wanted a badass daily V8 that I will eventually put work into mod wise. I have a 6.4 intake manifold that I still have to port out that I eventually want to swap the 5.7 intake for. Got a shopping list and I’m gathering parts as time goes by a bit to do most of the work myself.
You don’t have to do a tremendous amount of things to a 6.4. Literally buy the drop in forged piston and rods, a super charger, a more aggressive cam is optional the stock one is fine and you’re good to go. That should be good enough to get you in the ballpark of 700 whp safely before you have to do trans work. Then you can port the heads and add even more air with different air boxes and yeah 1000 hp isn’t hard to obtain
Good stuff. So much more available for the 5.7s. You can beef up the internals of the short block eagle 5.7s and push it even more also. I'll be there real soon.
350s as a WHOLE are very iconic, and for good reason. The fact that it's a HEMI makes it even better; the aged, tried and true powerhouse, is this American staple 🔥.
@@demarcusbody9437 and STILL has a lot of potential better not to boost any gas engine if you want longevity and low cost of ownership. Love to keep my 2012 RAM 1500 HEMI 5.7 with near 140,000 and rather do tune up, upgrade air cleaner filter and free flow exhaust with 5 inch tips for increase performance, mpgs, towing power, highway cruising, and again longevity.
Just picked up my 2022 Dodge Charger RT It comes with super track pack not sure if it makes a difference .I’m new to the HEMI life , been having a mopar car as I got my 2015 Chrysler 300 . Nice video
Agreed. They are the most cost affective to modify if you so choose. They also put out very good horsepower for the price they go for. In the 2500/3500 trucks specifically, I love the 5.7 hemi because it doesn’t have MDS, so it’s always a straight V8. As where the 6.4 hemi in the trucks have mds.
@@michaellarrick8881 “I love the 5.7 hemi because it doesn’t have mds so it’s always a straight v8” that statement implies you’re talking about 5.7 hemis as a whole not one specific model. But just sharing knowledge my friend it’s nothing major to debate about
The problem is this stuff isn’t cheap. Depending on what power you’re looking for you’re better off buying a scat or cat. The 5.7 is just for people who enjoy custom builds ❤
Did you not watch the whole video? Basically he's saying there's really no point in buying a scatpack because the engine is weak and will break. You will spend even more money on the 6.4 to get it strong enough to be boosted safely. Either go with a hellcat engine, or go with the 5.7 hemi. Leave the scatpack engine alone.
I have a 2019 charger RT I thought about doing a v10 viper swap but idk. If I decide to keep the 5.7 I'm definitely going with a whipple supercharger & alot of hellcat parts 🤣 E85 & Slicks on the back. Tbh.. but rn I'm saving & in the middle of doing my awd k24 swap in my 2001 saturn sc2
The ring lands on 6.4’s are to tight; the extra heat from boost will cause them to overheat, and once they overheat they will pop rings & pistons. That awesome that he mentioned Richard Holdener & MMX. MMX built my 394Ci 6.4l stroker in my truck💪🏻. Byron at MMX is the man!
I been tryna tell people this ages but no one listens. Dodge restricted the 5.7l and squeezed the 6.4l for all it's got. In reality it's 345 vs 392, the gap is not that big it's .7l. That's like comparing a honda b18 and a k24 The stock hp gap is not that big and those are dohc engines.
Or to make it cheaper/easier, go ahead and get a 5.7 out of an 09-current hemi since they already have eagle heads. Trust me you can find them like candy.
@@erikbergstrom258 that’s easily fixed besides it’d take over 500 hp and some serious driving to break either one. Then supercharge or turbocharge and your good to go
There is a 6.1 here in my town at the local junkyard for $400. It’s in a wrecked SRT Magnum. I’m thinking about buying it my Magnum has the 5.7 in it. The 6.1 would be a nice upgrade huh?
@@mr84ttop34 You can get stroker kits for 6.1s up to 426. Someone else said it, the 6.1 is obsolete, but it's also horribly slept on. You still want to check cams and lifters, but that engine was nasty when it came out.
From the standpoint that you can buy a 5.7 for less than a 6.4 and throw a supercharger onto it and have more HP than a 6.4 for less money, yeah, its better. If you want to go NA and try to match the 6.4 in power, not so much. Unfortunately the 5.7 doesn't handle boost as well as others though. So if you want to go for 4-didgit HP numbers, you're going to have to build the shit out of your engine to get there without it blowing up.
These 5.7 hemi engines are notorious for lifters seizing up due to oil starvation. Ultimately causing the camshaft lobes to have grooves in them. The reason for oil starvation is due to poor engineering by Dodge/Fiat. The camshaft sits to high inside the engine for oil to reach, especially during idle.
You nailed it. Mostly caused by engine idle. I've had a 2012 Ram HEMI with over 107,000 miles and it didn't tick. My 2017 Sport with 32,000 and over 150 idle hours ticks every time on start
I’d take my 6.4 any day , I loved my 5.7 but it just wasn’t there if you want to dump 10k+ into the 5.7 just to make it “ as fast a 6.4 “ no point in my opinion I’ve seen plenty of 6.4 run just fine with boost
LMFAO 😅 won't take 10k to make it what a 6.4 is. If you put 7k into a 6.4 and 7 into a 5.7 you have a 5.7 that will be equal if not better and more reliable lmfao 😅 you missed the point of your weak drivetrain.
@@leopapio683 da hell did you do to get the T case to blow ?? 😬 im almost to 200k and it hasnt been stock for 135k. Granted its starting to act out but its still takin 472 TQ, barely though. I beat the shit outta this poor whale 🤣
What’s up with the 6.1 Hemi? Would that be easier to build power compared to the 5.7? I feel like the 6.1 would see better power increases on low boost.
The 6.1 is an absolute monster when treated right!!!!!! I had a stroked 5.7 that started knocking reeeaaallyyy bad so I’m currently now looking for a 6.1 to throw in there with a 270 comp cam, longtube kooks headers, throttle body spacer, tune & some good ol 305s, possibly 315s in the rear!!!
Thank you for speaking some serious truths! Too many people boring out their blocks, with thin cylinder walls, thin head gasket surfaces, long strokers putting a whole lot of side load on the cylinder walls, and with short stroker pistons! SMH! For boost, you need stout, And the 5.7 hemi is stouter than any other.
I find the 5.7 is a lot alike gms vortecs. Oil pump on the front, pushrod engine everything real easy to access. Both engines are real similar that’s what I like about the hemi and the vortecs.
So far my build on my 300c . 3.09 LSD .220/330 hrt stage 3 cam kit . Ported eagle heads . 397 stroker kit . Hellcat injectors . Long tube headers . True dual exhaust with magnaflow performance mufflers without resonators . Mmx ported hellcat throttle body . Mmx hellcat supercharger adapter kit . Hellcat supercharger . 180 t stat . Diablo sport 93 octane/ custom tune TBH I'm just trying to be a sleeper idc if I can't outrun a cat I just want to shock people outside of Mopar because I know a lot of Chevy guys think that the 300s don't have v8s so I wanna have that sleeper status ....... even though my cam and exhaust might give it away lol😂
he speaks the truth. I have a 2021 chrysler 300s with a 5.7, i slapped a 3.0L whipple on it with a mild tune for daily driving and all stock internals and exhaust (sleeper quiet) . It dynos at 610hp crank, 515rwhp with only 7lb of boost. Once the warranty is up i am swapping internals and opening it up.
When I was a kid I convinced my midlife crisis grandad to buy a 2005 ruby red magnum rt (but not the r/t two different trims). He put throttle body spacers, borla cat backs, and a cold air intake and a chip and for 2005 it was damn near Corvette quick
the scat pack 392 was made to be a boost off of the original 5.7 380 HP product. It (392) does not do well with higher RPM (past 6200) applications. The best option that I saw was a 6.1L off of a early Jeep Grand Cherokee (2008-2010) SRT that had simply a blower and injectors on it - made 600/600 (HP/TQ) and couldn't keep transfer cases and transmissions since the original 5 speed trans they had on those was weak..... As some of the earlier commenters also said - the early hemi (before MDS) was basically crippled - it could make 500 HP stock with the correct programming however to make it more reliable and streetable they "detuned" it to the 350 levels that you saw in stock form. Also isn't it interesting that it only had a compression ratio of 9.6:1 stock (ASKING FOR BOOST)......
U right on point my guy... ppl are sleeping on these 5.7 Hemis.... I own 2 of them ..a 2004 Hemi Ram 1500 & a 2014 Challenger R/T .. I love both of 'em
I have a 5.7 RT just brought it, its a 2017 only had 26,000 miles on it. I love it. The problem with these dodge’s is everybody wants to buy one and everybody wants to go fast but these dudes can barely drive a Ford. They say with great power comes great responsibility, with a Dodge comes great responsibility, that’s why these hellcats and scat packs and demons you see on the back of a trailer heading to the shop because they all smashed up. all I need to do is just get in front of a bunch of slow knuckleheads. I ain’t trying to race Nobody, not trying to smash my car and I’m not trying to get my insurance rate to go through the roof or my license taken.
It just has a lower compression ratio stock.... I love how that 5.7 hemi was in heavy duty trucks. Day one was a monster... Thinking about the same power as an l q9
Couldn’t be happier with my 2007 Daytona charger with the 5.7, I’ve only done cams and heads and at 325,000 miles on it it’s still smooth and clean. It’s been babied tho
The problem is you have to disassemble the block and put new piston rings. That’s the flaw in the early hemis. At this point there’s no reason for me to tear apart the block unless it takes a dump on me. So I’m okay with my stock 345HP.
Great info. I wanna find an old police intereptor Charger and slap a supercharger on it, but I'm tempted to do my 5.7 Hemi 4x4, now, with the hellcat upgrade.
Not going to lie though. I really like that. 4.7 l power tech engine kind of slept on imagine they just made it bigger instead of making a 5.7 hemi and we had a single overhead cam I've seen those 4.7 l with lots of mileage. My friend has one with 310,000 mi in a Dakota... He is a mechanic and it also was on its second transmission
This is good information to know and I've always wanted older models as project cars because it's easier to hook them up versus the newer beefed up engines that they have now in a lot of models cars.
built a awd police charger with a 5.7 and xs turbo made 780 awhp. Sold it and now building an 02 tahoe with a 6.0 turbo 4x4 leveled on 35s. Gonna be wild. hemi or ls both reliable with some modifications.
@@hunterterrenceth The Magnum? I know there're some things you can do with them like upgrading the heads and probably even boost but there's not going to be as much support out there. Either way, it would be a nice upgrade from the 3.9 in my '88. I'd like to keep the 5 speed but I'll probably need a beefier one.
You save me alot of time an money with this message I brought a V6 2011 challenger just to play with as a stree car I was goin to get hellcat motor put in it an 😂 sneak on someone at the light but Im going to swap it for a 5.7 now
I've been a fan of the 5.7 Hemis because the potential these motors have. 6.4 block is the same as the 5.7 block. The cylinder walls on a 5.7 are thick to produce a lot of power and especially if you want to forge the bottom end for stupid power. The 6.4 is alright if your keeping it N/A and just doing a step up cam upgrade with bolt ons but not good enough for boost. I'm curious though.. What does everyone think about the 6.1 Hemi? I thought there's good potential with the 6.1 Hemi too.
Bro speaking facts my 2020 Laramie night edition with the 5.7 hemi and let me tell you I got my shit pushing 650 hp (at the wheels) with some turbos I’ve done put 90k miles on it zero problems I ain’t even got a transmission slip or anything love this truck if you get a ram please do yourself a favor and get the hemi you won’t be let down I promise
I have a 2009 5.7 that I’m swapping into a 92 D150 pickup. It will have a 6 speed manual and be under 3800 pounds. It should be a fun little street truck.
