MrMurph111 Yo what did u have to change on your 5.7 to run it? And did u have to do any other crazy upgrades like fuel injectors/ fuel system and tranny? Also what year? I wanna supercharge my 05 ram but don’t wanna blow it lol
TC14KID Well technically the supercharger is for a Ford 3v engine which I have but if you keep things basic with how it’s designed you shouldn’t need to do any internal engine mods....trans you might want to do a shift kit or other small part upgrades. Bigger injectors are recommended, usually 39lb for starters. Fuel pump upgrade is a must and tuning on your stock computer. This setup from magnuson is designed to give you 135-150 rwhp over stock. There is a great website called departmentofboost.com that has a lot of basic info on supercharger power numbers and expected cost at each desired level. Hope this helps.
My 03 1500 5.7 has performance exhausts, K&N, hypertech programmer. We all know the old 5.7 makes 345 stock. K&N air intake gives... eh 15hp maybe 20hp. I like it on the truck it suits it. Hypertech programmer you can set your RPM settings, power, fuel. Trucks been on a 93 gas tune for a long time it’s probably making 390hp 395hp I’m liking where it’s at a lot. The newer 5.7s make that power stock but thing is mine feels like much much more, when you want the power it’s there the truck will instantly downshift and pull its fantastic. Maxed out on the power system I’m guessing it’ll do a 415hp. It’s been a while since I touched it. I like what it’s on now so I kept it and drove the truck
the issue was probably a poor choice in cam, hemi heads love high rpm, and really start breathing over 4.5k. Thats the reason street hemis kinda suck ass compared to ls motors. He probably could have made the same (if not more) power with the stock heads.
@@cnp-auto-1445 I agree. It wasn't the heads fault, just not enough cam/engine to need them. Stock heads still more than enough. I think that's why they didn't give TQ/HP peak rpm's or overlay the curves: Because they had to spin the last combo higher to get a HP gain.
Love your channel!! Great work thanks. I think that hemi intake, whilst very nice is too much for the motor & the big plenum volume & short runners is hurting airspeed. So you really need more compression & higher rpm or go to a X shaped single carb style one like that afr two piece plastic one you featured recently. Just s thought 💭
Wouldn't do as good. Just look at the horsepower today's cars are getting with EFI vs old engines with larger displacements and carbs. No comparison and in this case the HP wasn't limited by the fuel delivery
Well I know on LS engines a carb swap with a tall tunner intake yield some pretty good gains. Problem is most efi intakes don't give you a straight shot into the port unlike carb intakes like the victor jr. I know one thing those patriot heads are garbage, be better off doing a mild port on the stocks and unshrouding the valves a little if you could. I think that would yield better returns.
It'd do about the same for max horsepower (because that's basically about how much air/fuel you can pump) but it would lose out in power under the curve. Fuel injection can adjust A/F ratio at any point in the range, for any temperature. Carbs are limited in that regard.
Yeah that's def sad especially at the cost of the parts I would be willing to bet the cost of a supercharger on stock would be cheaper and make more power. Flow numbers on those ported heads arnt very good over stock
Not to sound like a Fanboy here but you can go to a junkyard to get a ls based 4.8 for $500 do a cam swap Decap injectors and make 450hp and you'd still be under $1,000
Yup was thinking the same thing and I'm not a fanboy either. Can't buy what you want if you're like me so you got to go the cheapest bang for the buck. It's the cheapest hp to dollar ratio that I can find....
Back in the day. And i still have it. You could use the bar that held the spare tire would screw right int the cam and we would pull out the cam with that
in this next step we replace the block with an aluminum billet custom machined one with a 6 inch bore and a 12 inch stroke .. then we add titanium heads and a 671 blower with three 300 shots of nitrous... but the water pump bolts stay the same unfortunately they aren't used on this engine but we will be using them to bolt down the tachometer on the dash
You gus should dyno the 5.7l with stock parts. Like oem 5.7l manifold & with the 6.4l version & long tubes, also the 5.7l intake vs the 6.4l intake & efi
I don't always lower myself for budget built engines but when i do i always use 3 different cams and change the heads and other components for the minor cost of thousands of extra dollars but its on a budget still because i get the money off the money tree in the back yard.
The head flow chart showing stock having significantly more flow in lower lifts, where the cam spends most of its time open. Not buying their port job lol
I'm used to 2 valve Ford Modular engines which flow around 190 CFM stock so I saw 300 out of a stock Hemi head and went "yup, no need to mess with that!"
@@pw383426 Yeah, that's why a stock 2V GT makes 260 HP and I believe the Police Interceptor Crown Vics made a little less than that. The Coyote was when Ford finally realized that they needed to put heads on an engine that actually flow (the Coyote is basically a poked and stroked 4.6 with some trick heads). Going back through history they've never been good at cylinder heads, in the 60s and 70s the Boss and Cleveland engines were the only ones that could ever breathe right. Even the big block engines were horribly choked. At 400 CFM I'd guess you're running a big cam and/or boost to take advantage of that much flow? For a budget engine swap I think the 5.7 Hemi is a bit of a hidden gem, my biggest issue is the parts interchangeability still isn't as good as a GM engine as much as I'm tired of seeing those swapped into everything.
@@406Steven I personally think some old D0VE heads from a BBF can be worked to flow 280ish from past projects I've had. And you can go up CI to a 514 or 545CI pretty easy too. I def want to give a 5.7 HEMI a run as well! Most of my experience is from small block mopars so would love to know the real differences in ownership
I see all the bad comments and I mostly agree. Heads are not worth the 30HP however this 345CID is already making 400HP stock. Thats over 1HP per CI. Most hot rod motor builders are way happy when they get to 1HP per CI so to me that shows that the 5.7 is pretty much built and tuned to make as much as it can from the factory. Heads can only suck the air being demanded in other words they could have put on heads 5 times as big and it still would do anymore because the displacement is only pulling so much CFM however I would have like to seen a test where they plopped on a roots blower and run that against the stock heads vs the news ones. I bet the numbers would be way different and way bigger with the newer heads
That's not entirely stock. The intake is way different from a truck style intake, or even a car style for that matter, and so is the throttle body. The ECU they are using is much better than a factory one too. So, there's where most of your gains came from. The cams they chose were small. (lift wise). Eagle heads, outflow the pre eagle ones and they outflow the 6.1 heads at some points, but between the two heads, they are nearly the same. The bottleneck, as with most engines, is the exhaust ports, and exhaust valve size. You'll be surprised what gains can be made by increasing the exhaust valve size slightly, opening up the valve hole, and giving the port some love too. Torque Improves quite a bit. If the valve can't be upsized, then duration and valve lift can be tweaked a bit to allow the valve to be open longer and higher to help airflow out of the cylinder. With these engines though, piston to valve clearance starts to be an issue for the exhaust valve with the higher lifts, so, care must be taken to have the space needed and still get a good benefit from it.
Why would you ever swap on a head that loses that much low lift flow when your only turning 6,000 rpm? Would have had a much better engine with the factory heads.
also....delete the MDS system and replace all lifers with regular ones and tune the computer to always have the MDS mose on. this pressurizes the system all the time which helps to lube the lifters so you don't get lifter and cam failure like some get. you delete the MDS system by removing the solenoids(4 of them) and replacing them with cap blockers. I discovered that by replacing a, 2009 and new 5.7 Hemi oil pump with a hellcats oil pump, it helps with the hemi tick and at idle, it helps to continue to oil the lifters. at idle, the hellcat oil pump add about another 28 PSI and at cruise, adds another 38 PSI of oil pressure. and the hellcat oil pump is only 180 bucks. worth the price to help make sure the lifters get continued oil to not cause the lifter and cam failure. (hemi tick)
It was an early 2000s RAM motor. It didn't have MDS to begin with as it came blocked off from the factory. It's also unable to have a hellcat oil pump mounted to it because there is a slight difference in the mounting between early 2000s pre-eagle hemis and the Eagle VVTs. Only 2009+ can use hellcat oil pumps.
I put a 200 shot of nitrous on my 5.7 challenger 6speed and went 12.4 with nos on nittos I had the suspension upgraded with the hop not kit and that worked well but factory best I went was 13.8 not bad for a car that weighs 4300 lbs with me in it
My 5.7 Hemi at startup runs rite to 2k rpm then slowly drops to 8-900 rpm, so i hold throttle to the floor so it doesn't start and i can prime it a bit before it starts that seems to start smoother by doing this.
yeah i think most of the power gains were from the intake and EFI, they didnt do a base run and they didnt include the EFI system and intake in the price of the build. i think that efi is like a grand by itself.
thelasthallow plus probably $800 for the intake. And I'm pretty sure they didn't include the cost of the Mahle pistons either. Probably closer to $5-6,000 total for the build for and extra 60horsepower? Ha...haha...hahahaha...nope.
@@thelasthallow Dude did u listen to the video? They stated in the first minute that when it was torn down they replaced only the pistons, intake and installed the Fast fuel system setup. It then made 400 hp 50 more than stock.
@@mattmoilanen3813 i remember now that you stated that, so yeah 2 grand for the engine and probably another 3 grand for the rest of the setup, 3k gets you 60HP lol thats really bad.
A lot of TH-cam engine builders here in the comments. The intake they are using is definitely for future boost upgrades and sucks for their EFI throttle body setup. I'm sure they know they are leaving a lot of power on the table so they can save some money for a future supercharger. Also, that engine made 345hp stock. They are now over 100hp over stock which is awesome for a pump gas street 5.7L that started with good power from the factory. Not too bad for about $1,800.
There is a reason folks are swapping LS motors into vehicles that first came equipped with this mill.... I'm a Chevy guy but bought a Magnum wagon with a hemi because I needes a low profile hauler. It moved pretty damn good to begin with. Already had better exhaust amd a good CAI when I got it. Figured a would throw a few more tricks at it for fun. Started researching prices. Wholy wow. I can buy parts and pay to have them installed for less than the parts alone for the hemi. Not complaining, I like my wagon, it scoots. But it is staying just the way I bought it and I will save the money for my LS swap Cutlass.
If or when I have the tools, and some I would probably make a build like that to hoist down into a 70's or newer muscle car, or truck!!! Maybe with the supercharger plate a super charger and air intake scoop in a 1974 Hemi cuda!!!
they don't tell you the total cost for this build. These are rough estimated numbers for a "budget" build. $2000 for engine. $247 Engine gasket set $855 Mahle Piston w/rings set $61 Rod bearings $61 Main bearings $529 Indy mod man intake manifold $503 Doug's ceramic coated headers $919 Fast ez efi self tuning system $550 MSD Hemi 6 ignition controller $638 Meziere electric water pump $268 Meziere backing plate $75 Cloyes timing chain $30 trick flow specialties cam handle $393 Camshaft $1400 Patriot Performance stage 2 cnc heads (based on their $1800 heads and cam claim). I highly doubt Patriot sold a pair of heads that damn cheap, but whatever. $40 pair of head bolts $45 royal purple engine oil Grand total of $8614 for this Hemi "budget" build. I don't know about you guys but that busted my budget. This does not include and the nickel and dime bullhsit to make this happen. And again, i highly doubt those cylinder heads and cam combo was $1800. Why not just find yourself a 6.4 392 hemi to start with. They're rated at 485hp bone stock with factory exhaust manifolds. I see them from $5500 and up. For $8600 I'm sure you can find a take out with factory harness and ecu. You'd have a better base to start with when you begin modifying.
This show literally appeals to high school kids in their first year of auto tech... anyone experienced in the field would see what a complete joke this whole thing is
Chrysler updated the head design in 2009. I would be curious to see how the same setup would do with the updated head. Probably a far cheaper route than porting.
Great informative video, but I think the horsepower gain wasn't very impressive for the cost ..additionally the cost tally was missing new bolts, gaskets, oil, water pump setup, efi system, intake and plates ..which I'm sure adds at least another $2k easy. So 60hp for $4k either shows the engine is already squeezed from factory for efficiency (kudos Chrysler engineers) or your selections weren't up to the task. Just saying.....
This show is more a bunch of advertisements for various sponsors. Still fun to watch but they shouldn't be doing "budget" builds. Take that stock hemi, stock intake, stock air box, stock ECU and tune it and you've got a great budget engine swap with no "build" necessary. Remember not so long ago when people were jacked to get 400 HP out of a SBC in their hot rod? This engine will do that stock with a tune.
@@406Steven that's true but it's even cheaper to start out by just buying one of the 6.1 or 6 .4L that start anywhere from 425 to 480 horse. Just today on the FB market place I saw a 2013 300 SRT low mileage 6. 4 with trans for $6500
The new 392 Hemi makes 485 HP and the new 3rd gen Coyote V8 in the 2018 and 2019 Mustang GT makes 460 HP which is the same as this used built 5.7L Hemi V8 and the new LT1 V8 in the SS Camaro makes 455 HP.
at 8:23 they show the cost of their upgrade but they dont show the cost of the EFI system (includes carb) and the cost of the new intake manifold. the EFI is probably a grand by itself...
The gen 3 hemi in my 09 challenger went into limp mode while the wife was driving it... Got it tore open and found metal on the MDS solenoids under the intake... The oil didnt look to bad however... After talking to Wichita Dyno and a few other places, the general consensus was that the engine was cooked and needs replaced... Can I just send my car to yall and have you make my challenger great again? I have burnouts to do at the Freedom Factory...
If I do the mds delete plugs on my 2007 Jeep Grand Cherokee Overland 5.7 liter Hemi and just leave the mds solenoids plugged in but not in the engine but some place under hood will the mds disengage and the warning lights stay off???? Maybe if I set them in a plastic coffee canisters sealed with some oil in it!
there was a lot of crap on that camshaft when it was pulled out considering its only been run on the dyno a few times.... did you drop that block in the shaker thingy tub thing? probably should have done that since you own it now.
the more i watch what it takes in time and money to pull 425hp+ out of a gen three hemi...the more I realize how affordable a stroker 318 or 360 is. 392 or 408 cid and affordable aftermarket heads, just decide if you want Magnum or your valves on a shaft. The issue is finding EFI, since most V8s from the EFI era were trying to make torque in a truck. With a Ford Windsor, its easier to find a used EFI setup that out breathes a GM TPI.
I would love to know how to do this stuff to my 5.7 hemi charger r/t road and track pack but I can't fathom of where to begin and what all is required when installing parts wish I had some help or knowledge to help get me there over time
All that for 55 extra horsepower ??? The truck goes back to the dealership 😂😂😂 “like new, only driven around the lot”??? Who does that to a new vehicle!!!!
Hey guys I love what you guys did. But just out of curiosity can you guys do a 274 comp cam sway or even a stage 3 cam from Texas speed and performance.
Is the original harness necessary or are harnesses sold that'll allow it to run without a car and all the superfluous sensors ? I'm asking for research purposes (putting a v8 where a v8 need not be)
hello, so you guys make an excellent presentation, no comments i follow you here in brazil but i would like to know why the assembly is not done so i say less quickly, and when i watch i learn more and more
If you can do a 4.7 magnum video to see how much horsepower can that take from a turbo? That will be a great video everyone always do the 5.7 But there are no 4.7 engine videos
dodge says their head bolts are reusable. I would almost bet the 6.4L intake would make more power than that thing you guys have. other channel made almost 500hp on the stock heads with a different kind of intake. a sniper 837031
could have had better results with just blending the bowls on the stock heads, longer valves with heaver springs, they lost all that low lift flow with those other heads. 🤦♂️
I remember when BES brought a Gen 3 HEMI to the Engine Masters Competition and made 700 hp with factory block and heads.

Better money would have been spent using 6.1 srt8 heads, then test them ported. With the bigger bump stick.

It wasn't the heads fault, just not enough cam/engine to need them. Stock heads still more than enough.
I think that's why they didn't give TQ/HP peak rpm's or overlay the curves: Because they had to spin the last combo higher to get a HP gain.
Indy Rock yes, cam fell off before it hit the ideal flow. They either needed a bigger inch engine or a higher rpm engine.
@@cnp-auto-1445it's probably the hi-ram. That is an intake that is ideal at high rpm and their cam's operating range only went to like 6400.

There need to be more hemi builds and swaps
No there don't.
@@SomethingFunny454 better than the LS
@@knuckleberry4720 Not at the track or in a truck. Fix it again Tony.
@@knuckleberry4720 what a joke! If that hemi was better than a LS everyone would be swapping them instead of the LS.
@@SomethingFunny454 lol ever here of a hellcat
Nice work!
Side note: always fun to see how far the steam engines pull.... not a lot of hp, mountains of torque
Love your channel!! Great work thanks. I think that hemi intake, whilst very nice is too much for the motor & the big plenum volume & short runners is hurting airspeed. So you really need more compression & higher rpm or go to a X shaped single carb style one like that afr two piece plastic one you featured recently.
Just s thought 💭
I'd be curious to see what a good old conventional carb like a Holley 850 double pumper would do in place of that fuel injection system.
Wouldn't do as good. Just look at the horsepower today's cars are getting with EFI vs old engines with larger displacements and carbs. No comparison and in this case the HP wasn't limited by the fuel delivery
Proper port injection, ITBs and a proper ECU would leave both of those in the weeds
@@sidewaysdanny hahaha.
Well I know on LS engines a carb swap with a tall tunner intake yield some pretty good gains. Problem is most efi intakes don't give you a straight shot into the port unlike carb intakes like the victor jr. I know one thing those patriot heads are garbage, be better off doing a mild port on the stocks and unshrouding the valves a little if you could. I think that would yield better returns.
It'd do about the same for max horsepower (because that's basically about how much air/fuel you can pump) but it would lose out in power under the curve. Fuel injection can adjust A/F ratio at any point in the range, for any temperature. Carbs are limited in that regard.
Only 29Hp gain with heads and cam over cam alone! That's sad!
Consider it’s the same fuel system and no boost what did you expect ! 100 hp gain. Get real
With stock heads, that's not bad.. lack of head port volume on any motor will limit power
Yeah that's def sad especially at the cost of the parts I would be willing to bet the cost of a supercharger on stock would be cheaper and make more power. Flow numbers on those ported heads arnt very good over stock
Yeah they pretty much spit out 2 grand and got like 60 horsepower
Sad it is but I guess it just means that the stock heads were a very good flowing head when you don't gain much from aftermarket.
Not to sound like a Fanboy here but you can go to a junkyard to get a ls based 4.8 for $500 do a cam swap Decap injectors and make 450hp and you'd still be under $1,000
Yup was thinking the same thing and I'm not a fanboy either. Can't buy what you want if you're like me so you got to go the cheapest bang for the buck. It's the cheapest hp to dollar ratio that I can find....
You projecting it aint that cheap
Back in the day. And i still have it. You could use the bar that held the spare tire would screw right int the cam and we would pull out the cam with that
in this next step we replace the block with an aluminum billet custom machined one with a 6 inch bore and a 12 inch stroke .. then we add titanium heads and a 671 blower with three 300 shots of nitrous... but the water pump bolts stay the same unfortunately they aren't used on this engine but we will be using them to bolt down the tachometer on the dash
I wish that they would use other camshafts besides comp all the time for the mopar stuff
It's one of their sponsors what do you expect
HAPPY NATIONAL HEMI DAY!!!! 4/26/24
You gus should dyno the 5.7l with stock parts. Like oem 5.7l manifold & with the 6.4l version & long tubes, also the 5.7l intake vs the 6.4l intake & efi
I don't always lower myself for budget built engines but when i do i always use 3 different cams and change the heads and other components for the minor cost of thousands of extra dollars but its on a budget still because i get the money off the money tree in the back yard.
The head flow chart showing stock having significantly more flow in lower lifts, where the cam spends most of its time open. Not buying their port job lol
I'm used to 2 valve Ford Modular engines which flow around 190 CFM stock so I saw 300 out of a stock Hemi head and went "yup, no need to mess with that!"
@@406Steven 190cfm @28in is rough bruh that's hard to get around lol. My normal goal is usually around 400cfm on most projects
@@pw383426 Yeah, that's why a stock 2V GT makes 260 HP and I believe the Police Interceptor Crown Vics made a little less than that. The Coyote was when Ford finally realized that they needed to put heads on an engine that actually flow (the Coyote is basically a poked and stroked 4.6 with some trick heads). Going back through history they've never been good at cylinder heads, in the 60s and 70s the Boss and Cleveland engines were the only ones that could ever breathe right. Even the big block engines were horribly choked. At 400 CFM I'd guess you're running a big cam and/or boost to take advantage of that much flow? For a budget engine swap I think the 5.7 Hemi is a bit of a hidden gem, my biggest issue is the parts interchangeability still isn't as good as a GM engine as much as I'm tired of seeing those swapped into everything.
@@406Steven I personally think some old D0VE heads from a BBF can be worked to flow 280ish from past projects I've had. And you can go up CI to a 514 or 545CI pretty easy too. I def want to give a 5.7 HEMI a run as well! Most of my experience is from small block mopars so would love to know the real differences in ownership
Back to the dealership after smoking the trans lol. Truck still had a window sticker in it.
I see all the bad comments and I mostly agree. Heads are not worth the 30HP however this 345CID is already making 400HP stock. Thats over 1HP per CI. Most hot rod motor builders are way happy when they get to 1HP per CI so to me that shows that the 5.7 is pretty much built and tuned to make as much as it can from the factory. Heads can only suck the air being demanded in other words they could have put on heads 5 times as big and it still would do anymore because the displacement is only pulling so much CFM however I would have like to seen a test where they plopped on a roots blower and run that against the stock heads vs the news ones. I bet the numbers would be way different and way bigger with the newer heads
That's not entirely stock. The intake is way different from a truck style intake, or even a car style for that matter, and so is the throttle body. The ECU they are using is much better than a factory one too. So, there's where most of your gains came from.
The cams they chose were small. (lift wise).
Eagle heads, outflow the pre eagle ones and they outflow the 6.1 heads at some points, but between the two heads, they are nearly the same. The bottleneck, as with most engines, is the exhaust ports, and exhaust valve size. You'll be surprised what gains can be made by increasing the exhaust valve size slightly, opening up the valve hole, and giving the port some love too. Torque Improves quite a bit. If the valve can't be upsized, then duration and valve lift can be tweaked a bit to allow the valve to be open longer and higher to help airflow out of the cylinder. With these engines though, piston to valve clearance starts to be an issue for the exhaust valve with the higher lifts, so, care must be taken to have the space needed and still get a good benefit from it.
I had no idea this was all done in Tennessee. Crazy.
Why would you ever swap on a head that loses that much low lift flow when your only turning 6,000 rpm? Would have had a much better engine with the factory heads.
That's cuz this show is now more about product advertising than actual engine building
I think it needs the 2x quad carb setup for the heads to work right.
I would port and polish the factory head and fix the exhaust bolt issue with the 5.7 and call it a day.
@@jakey20022 Exhaust bolt issue?
@@snek9353 If it's like my truck, the cast iron exhaust manifold warps enough to snap the bolt on the end. I bet headers wouldn't have that problem.
also....delete the MDS system and replace all lifers with regular ones and tune the computer to always have the MDS mose on. this pressurizes the system all the time which helps to lube the lifters so you don't get lifter and cam failure like some get. you delete the MDS system by removing the solenoids(4 of them) and replacing them with cap blockers. I discovered that by replacing a, 2009 and new 5.7 Hemi oil pump with a hellcats oil pump, it helps with the hemi tick and at idle, it helps to continue to oil the lifters. at idle, the hellcat oil pump add about another 28 PSI and at cruise, adds another 38 PSI of oil pressure. and the hellcat oil pump is only 180 bucks. worth the price to help make sure the lifters get continued oil to not cause the lifter and cam failure. (hemi tick)
It was an early 2000s RAM motor. It didn't have MDS to begin with as it came blocked off from the factory. It's also unable to have a hellcat oil pump mounted to it because there is a slight difference in the mounting between early 2000s pre-eagle hemis and the Eagle VVTs. Only 2009+ can use hellcat oil pumps.
I put a 200 shot of nitrous on my 5.7 challenger 6speed and went 12.4 with nos on nittos I had the suspension upgraded with the hop not kit and that worked well but factory best I went was 13.8 not bad for a car that weighs 4300 lbs with me in it
My 5.7 Hemi at startup runs rite to 2k rpm then slowly drops to 8-900 rpm, so i hold throttle to the floor so it doesn't start and i can prime it a bit before it starts that seems to start smoother by doing this.
Proof that a baby cam and small head wont make much power
yeah i think most of the power gains were from the intake and EFI, they didnt do a base run and they didnt include the EFI system and intake in the price of the build. i think that efi is like a grand by itself.
thelasthallow more like $2,000.
thelasthallow plus probably $800 for the intake. And I'm pretty sure they didn't include the cost of the Mahle pistons either. Probably closer to $5-6,000 total for the build for and extra 60horsepower? Ha...haha...hahahaha...nope.
@@thelasthallow Dude did u listen to the video? They stated in the first minute that when it was torn down they replaced only the pistons, intake and installed the Fast fuel system setup. It then made 400 hp 50 more than stock.
@@mattmoilanen3813 i remember now that you stated that, so yeah 2 grand for the engine and probably another 3 grand for the rest of the setup, 3k gets you 60HP lol thats really bad.
I love these series. I can't wait for the next one.
I like to refer to the 5.7 hemi as the cam killer
A lot of TH-cam engine builders here in the comments. The intake they are using is definitely for future boost upgrades and sucks for their EFI throttle body setup. I'm sure they know they are leaving a lot of power on the table so they can save some money for a future supercharger. Also, that engine made 345hp stock. They are now over 100hp over stock which is awesome for a pump gas street 5.7L that started with good power from the factory. Not too bad for about $1,800.
I'd like to see more info on the intake manifold and possible tops available. Not much cam for what appears to be a short runner intake manifold.
REAL MAN'S CHANNEL
There is a reason folks are swapping LS motors into vehicles that first came equipped with this mill.... I'm a Chevy guy but bought a Magnum wagon with a hemi because I needes a low profile hauler. It moved pretty damn good to begin with. Already had better exhaust amd a good CAI when I got it. Figured a would throw a few more tricks at it for fun. Started researching prices. Wholy wow. I can buy parts and pay to have them installed for less than the parts alone for the hemi. Not complaining, I like my wagon, it scoots. But it is staying just the way I bought it and I will save the money for my LS swap Cutlass.
@@jakevalent6180 ironically I did about a year ago maybe two now
If or when I have the tools, and some I would probably make a build like that to hoist down into a 70's or newer muscle car, or truck!!! Maybe with the supercharger plate a super charger and air intake scoop in a 1974 Hemi cuda!!!
The wing on that charger is ridiculous.
I use Royal Purple as well.
I use it because the oil is purple. That’s why. Lol
Notice how the greenhorn puts the cam in what a Lou Lou
they don't tell you the total cost for this build.
These are rough estimated numbers for a "budget" build.
$2000 for engine.
$247 Engine gasket set
$855 Mahle Piston w/rings set
$61 Rod bearings
$61 Main bearings
$529 Indy mod man intake manifold
$503 Doug's ceramic coated headers
$919 Fast ez efi self tuning system
$550 MSD Hemi 6 ignition controller
$638 Meziere electric water pump
$268 Meziere backing plate
$75 Cloyes timing chain
$30 trick flow specialties cam handle
$393 Camshaft
$1400 Patriot Performance stage 2 cnc heads (based on their $1800 heads and cam claim). I highly doubt Patriot sold a pair of heads that damn cheap, but whatever.
$40 pair of head bolts
$45 royal purple engine oil
Grand total of $8614 for this Hemi "budget" build. I don't know about you guys but that busted my budget. This does not include and the nickel and dime bullhsit to make this happen. And again, i highly doubt those cylinder heads and cam combo was $1800.
Why not just find yourself a 6.4 392 hemi to start with. They're rated at 485hp bone stock with factory exhaust manifolds. I see them from $5500 and up. For $8600 I'm sure you can find a take out with factory harness and ecu. You'd have a better base to start with when you begin modifying.
This is true however this is the stage 2 upgrade not the factory. They really went out on this hop up. Good point though.
2 grand is cheap for that 50 k hemi.
"budget". Right.
Todd Golling they start off budget on stage 1 then the budget gets bigger in stages 2 & 3
@@hamreracing333 but for the price and the resulting hp doesn't make it worth it budget or not.
If you want a hemi it does
This show literally appeals to high school kids in their first year of auto tech... anyone experienced in the field would see what a complete joke this whole thing is
It is if your not poor
Just with the first cam upgrade its actually 86hp more with just a cam over stock(345hp) with the tri-power cam.
Chrysler updated the head design in 2009. I would be curious to see how the same setup would do with the updated head. Probably a far cheaper route than porting.
Please make a stage 3 for the 5.7. Possibly show how to install a supercharger.
Do the truck pull with an eco boost F-150. Either one will be fine.
Great informative video, but I think the horsepower gain wasn't very impressive for the cost ..additionally the cost tally was missing new bolts, gaskets, oil, water pump setup, efi system, intake and plates ..which I'm sure adds at least another $2k easy. So 60hp for $4k either shows the engine is already squeezed from factory for efficiency (kudos Chrysler engineers) or your selections weren't up to the task. Just saying.....
This show is more a bunch of advertisements for various sponsors. Still fun to watch but they shouldn't be doing "budget" builds. Take that stock hemi, stock intake, stock air box, stock ECU and tune it and you've got a great budget engine swap with no "build" necessary. Remember not so long ago when people were jacked to get 400 HP out of a SBC in their hot rod? This engine will do that stock with a tune.
@@406Steven that's true but it's even cheaper to start out by just buying one of the 6.1 or 6 .4L that start anywhere from 425 to 480 horse. Just today on the FB market place I saw a 2013 300 SRT low mileage 6. 4 with trans for $6500
The new 392 Hemi makes 485 HP and the new 3rd gen Coyote V8 in the 2018 and 2019 Mustang GT makes 460 HP which is the same as this used built 5.7L Hemi V8 and the new LT1 V8 in the SS Camaro makes 455 HP.
This is one giant infomercial.
at 8:23 they show the cost of their upgrade but they dont show the cost of the EFI system (includes carb) and the cost of the new intake manifold. the EFI is probably a grand by itself...
There's no carb ....
The gen 3 hemi in my 09 challenger went into limp mode while the wife was driving it... Got it tore open and found metal on the MDS solenoids under the intake... The oil didnt look to bad however... After talking to Wichita Dyno and a few other places, the general consensus was that the engine was cooked and needs replaced... Can I just send my car to yall and have you make my challenger great again? I have burnouts to do at the Freedom Factory...
If I do the mds delete plugs on my 2007 Jeep Grand Cherokee Overland 5.7 liter Hemi and just leave the mds solenoids plugged in but not in the engine but some place under hood will the mds disengage and the warning lights stay off???? Maybe if I set them in a plastic coffee canisters sealed with some oil in it!
Too expensive to modify Mopar engines. I learned the hard way.
Sounded like one of Jim Butlers sons @ 12:19 that said "I just hope it don't break",
there was a lot of crap on that camshaft when it was pulled out considering its only been run on the dyno a few times.... did you drop that block in the shaker thingy tub thing? probably should have done that since you own it now.
That wing on the charger. ...good lord lol.
We dun did bot this here Ing-Gine off that "Innar-Net".
Holy Sheet...
the more i watch what it takes in time and money to pull 425hp+ out of a gen three hemi...the more I realize how affordable a stroker 318 or 360 is. 392 or 408 cid and affordable aftermarket heads, just decide if you want Magnum or your valves on a shaft. The issue is finding EFI, since most V8s from the EFI era were trying to make torque in a truck. With a Ford Windsor, its easier to find a used EFI setup that out breathes a GM TPI.
I would love to know how to do this stuff to my 5.7 hemi charger r/t road and track pack but I can't fathom of where to begin and what all is required when installing parts wish I had some help or knowledge to help get me there over time
cam is the best swap for these motors
All that for 55 extra horsepower ??? The truck goes back to the dealership 😂😂😂 “like new, only driven around the lot”??? Who does that to a new vehicle!!!!
Hey guys I love what you guys did. But just out of curiosity can you guys do a 274 comp cam sway or even a stage 3 cam from Texas speed and performance.
This dude slurs his speech like my uncle after 8 shots of whiskey.
😂😂🤣😂
He has a speech impediment...
Dentures.
I'd love to drop that 5.7 in my truck
Great video
That charger is old enough to still have the Mercedes 722.6 transmission. It can handle a lot more than that.
So I was told you can’t do a cam swap with out pulling the heads. And removing the lifters . I have a gen 3 5.7 . I see you did it .
Is the original harness necessary or are harnesses sold that'll allow it to run without a car and all the superfluous sensors ?
I'm asking for research purposes (putting a v8 where a v8 need not be)
They'd make more horsepower pulling that Fast system off, putting the stock ecu back on, and getting a proper dyno tune using HP Tuners software.
This probably cost 6 grand to make 50 horsepower
These seem like high quality mods for daily drivers. Chrysler better send the cheque
hello, so you guys make an excellent presentation, no comments i follow you here in brazil but i would like to know why the assembly is not done so i say less quickly, and when i watch i learn more and more
If you can do a 4.7 magnum video to see how much horsepower can that take from a turbo? That will be a great video everyone always do the 5.7 But there are no 4.7 engine videos
Because 4.7s are junk
Is that self-tuner something that can be added to any vehicle to effectively eliminate trips to the dyno to get a tuneup?
I'd be curious what the modman with duel four barrels or the six pack would put out
dodge says their head bolts are reusable. I would almost bet the 6.4L intake would make more power than that thing you guys have. other channel made almost 500hp on the stock heads with a different kind of intake. a sniper 837031
could have had better results with just blending the bowls on the stock heads, longer valves with heaver springs, they lost all that low lift flow with those other heads. 🤦♂️
