Damn thats a significant difference Lol 505 hp out of a cam only Hemi ! Jeeeeez ! The old cammed Hemi didnt do too bad either, 437 hp is no slouch. Thanks
Id really like to see the OEM 392 camshaft compared to other aftermarket camshafts when installed in a late model 5.7 HEMI. There is a lot of debate whether it is worth putting the 392 camshaft in a 5.7 and you could finally put this to bed by comparing dyno charts!
The Comp cam that Richard replaced the stock cam with on the first test is just a tiny bit bigger than the 392 cam.. so the 392 cam would obviously do the same curve wise for the motor - just not make as much peak torque/hp.
@@richardholdener1727 Exactly and considering the Comp Cam you installed gave nearly identical down low numbers as the stock cam I would think if you are doing a cam swap and not trying to do something budget orientated that it would be better to just go with the Comp Cam.
ive tuned a ton of them with 392 cams, its worth it, the top end gains are huge. I'm actually tuning a 16 RT with a procharger and 6.4 cam right now. On 8 psi and long tubes its expected to make 575 at the wheels, it made 500 with blower only.
Great video Richard, glad to see these Hemi dyno videos and to see someone actually use the variable intake and variable cam timing. People seem to just lock those out and forget about it.
Your videos have helped me with my customers at my job for being a customer service advisor. I'm more able to inform them about the motor in their vehicle. I've always been a motor guy. Thanks for your videos and keep it up 👍👍 💯
I build these pretty regular here in Alabama. A Gen 3 hemi loves a good cam. I did a STG 3 in a 392, no other changes, stock exhaust, still has cats, etc only a cam and supporting springs and pushrods, picked up 54 rwhp... love my HEMIs
This goes to show that the engineers at dodge know what the hell they are doing, even in the early gen 3 hemis the aftermarket head engineers have a very hard time designing a better port than what comes from the factory and then the guys at dodge went and just made it even better
the late model "eagle" heads are fantastic, like you said the aftermarket head companies had a difficult time trying to make a better head. And honestly for the money aftermarket heads cost your better off lightly porting the factory units.
American manufactures have been getting a bum wrap for many years. Back in the late 80's, 90's I used to read online engine engineering inspectors rant "American engines are obsolete because they are still using timing chains and gears". I used to comment and say "and when they get all the issues worked out, there will be no more timing belts. All the research and development will be stolen and copied because you sure don't want a rubber belt operating those moving parts for any longer then 6 to 10 years". But I have to say, most people that own a foreign car follow the maintenance schedule like clock work.
@@Ed70Nova427 I've noticed that people that own foreign cars will buy extended warranties and always have their matinence done on time. Not to say people who buy domestics don't but some of the most clapped out vehicles that I've seen still putting around are american vehicles. Espcially the old trucks with the oldschool pushrod V8s, simple designs last forever it seems if you maintain them.
@@jaymoe5.7 You're absolutely right. Go to any parking lot and look for old cars and you will see some European but mostly American and maybe not in the best condition but that's what you'll find. It is difficult to find an 85 Camry or Honda almost zero Mitsubishi's and you'll find Datsun Z's. Again simple design. What gave American products the black eye is the paint and plastics. Of course this was blamed on upper management and number cruncher's and some might be due to that. But 90% of the failure in chemical based products was because all American manufacturers had to use only EPA approved paints and plastics while the rest of the world can build and sell cars in this country using whatever product there engineers came up with. I remember most everyone saying "I will never buy another American product because they use cheep junk materials", but in fact it was more expensive and well documented in the engineering quality control data to be of lesser quality then the previous materials but had to be put into use due to the approval of the EPA. Vinyl is cheaper than the material they had to engineer and they were already using it so it was way more cost effective but it was band in automotive production in the early 80's. In 2008 in the bankruptcy of GM, the government had the EPA loosen the specifications and allow the use of European grade plastics and paints. Overnight all of the big three changed to the European grade and that is why if you go to an American car dealership today and look at the interiors you will think it was made by a company in Europe. Anyway I own three Chevy's one Buick and one Pontiac at this time. I buy American as much as I can and turn down and or go without other's but its gotten to the point now that it's only a name on a box.
@@Ed70Nova427 yep thats exactly right, my 2011 dodge truck has a much nicer interior than my 2005 did, but I tell ya what, the sheet metal is waaayyy thinner than the body panels on my 79 Plymouth
Would be nice to see a pre eagle block with eagle heads and maximum camshaft with the stock pistons and some 392 exhaust manifolds. It's what most are doing on a budget
So iv ran Rams at the track for years and I can say this. I had a 2004 5.7 truck. 2wd short bed standard can. Ran like a 15.2 my crew cab 2017 ran 14.6 both had cold air intakes and a flowmaster muffler. I like the 17 ram a lot better for performance.
Yup and the aluminum that was being shaved off the cylinder head as the seat moved around. The compression and power stroke would blow all that stuff back up into the intake manifold and over time it gathers and really makes a mess. Then of course the seat gets kicked out and that's when the customer bring you the car. If you own a shop, the best thing to do is replace the manifold with a new one. I have to say one of the mechanics in the shop reused a manifold of his own but he spent hours flushing and shaking with gasoline and washing in soap and water. That was a couple years ago and he is still driving it, so I guess it has a chance to work. You want to see something scary. Poor some gasoline in a brand new intake, shake it around and poor it out. Sometimes you see black plastic strips or shavings and not only in the Chrysler manifolds.
I had good luck with my 05 hemi put the bigger 6.1l heads that also bumps up compression running a thicker head gasket 10.8-1 have to run 91 6.1 cam and balancer and a 2015 5.7 hemi intake seems to work well
I believe the active dual runner intake is a 6.4 intake manifold not a 5.7 intake but can be made to work with the 5.7. I have been seeing many tuners are now deactivating the VVT because it actually causes problems and less hp. My understanding it is mainly for emissions and not an advantage for performance.
Watched all your Gen 3 hemi videos and have your book about building them! Having a collection of Mopar engines sitting waiting for projects I’ve grown to love piecing together my Hemi for my 35 dodge pickup! Keep up the Mopar love!🤘🏽
Love it Richard! I’m currently building an early engine with late heads, pistons and rods. Looking forward to the bump in CR and flow while maintaining the more simple block and components!
I have one of each of these. My VVT is a '14 but I'm not sure it has the variable intake runner. I do know that the 2008 car is more fun to drive and is more responsive to throttle inputs. I tend to think it is also a bit quicker in 0 to 60 and quarter mile times. The '08 car is about 400 pounds lighter than the '14 so that may be some of it. Both cars (AWD 300's) have the 5 speed automatic transmission and 3.07 ratio but the '14 also has taller tires.
So happy to see some Gen 3 Hemi love but so disappointed to not see apples to apples testing. The cam specs should have been much closer to each other. Still happy to see some Hemi testing of any kind though. Thank you and keep it up. Lots of Hemi guys out here watching your channel 👍👍
As usual, more questions come from a good test.... Pistons that allow full VVT but don't sacrifice compression along with as much cam as is practical for a street application. Since it's really just VCT that doesn't allow a lot more cam but still. Great stuff!
I know you say that the variable valve timing on the later ones are better. But just like the long Runners on the intake, that's relative. I prefer the Simplicity of a fixed camshaft instead of variable valve timing. To me, it's simpler to work on and program.
@@slomo1010 Well, I have never owned or even driven one, so I'm not actually in a position to say. But I have heard a lot of good things about them (regarding power) from others who do drive them. As for Fiat, yes, it does seem like everything they touch turns into ****...
I think those numbers for the early Hemi 5.7 stuff are about right. I only see stock examples put down around 275-280ish on our DynoJet. I don’t see many early 5.7s break the 300whp mark until we start playing with the tune.
Would you be up to doing some injector end angle testing? Be great to see what gains could be made by moving them around with different duty cycles to also show how much it helps if you are only using 50 duty cycle so you have more room to move things around.
With eagle heads, high compression, and a cam, a pre-eagle hemi can put down some good power. Mine put down 413HP/418TQ with eagle heads, ebay longtubes, and a Comp cams Thumpr cam, and a stock eagle intake manifold, stock airbox.
Richard, love your vids and insight to all of this Hocus pocus engine magic. :). Ever thought about dyno'ing that late model 5.7, only using a 6.4L cam in it instead? That should preserve some of the low speed torque (through the ability to keep VVT happening)?
OEM hemi lifters are failing left and right, the shop I work at has been replacing cam and lifters in Ram trucks almost once a week, most have 80,000-120,000. The tiny local dealer stocks 6 cams, 96 lifters, and the parts guy says they sell at least one set every day over the counter, and two or three internal every day. I think I would consider aftermarket lifters if I was building one.
the reason that happens is because the cam is set very high in the block, so at an idle or low rpm the cam and lifters don't get much oil on them and they wear out. I wish dodge would wise up and put remote squirters or something over the cam to solve this problem.
Internal oiling is very poor to the camshaft. Needs to be kept at a reasonably high RPM to sling oil from the crank. Factory programming is absolutely for fuel economy, transmission will do its best to keep you in the highest gear possible for the longest period of time. Best bet is to limit the maximum gear, to keep the RPM's between 1,700 - 2,200 RPM at a minimum.
@@AmericaFirstKorey imagine "engineering an engine" so poorly, that typical driving kills valvetrain. Domestic auto manufacturers have thoroughly bought into planned obsolescence, and cheapening every item to the point where the vehicle is going to make it 100k and just self destruct.
Great vid. I've got an early gen III hemi, but now I'm thinking I need to find a later Gen III...so thanks for that. With aftermarket fuel-injection for early engines become more commonplace, one wonders if we'll ever see a dual-runner composite intake for engines like the SBC/BBC's?
I'd like to see a Gen 1 Chrysler Hemi 331. They're so rare and unusual and heavy and expensive! I don't think I've ever seen anybody Dyno a street built one. Maybe even a commando 273!
This is not confirmed but i got a few people talking about this: The older gen3 bottom end was built much tougher than the latest gens which means less to upgrade if you want to boost them. So ideally a gen3 5.7 with Magnum manifold and Eagle heads would the the perfect starting point for stupid numbers once you boost it.
Got an 08 engine, last week, ordered that exact cam you used, glad I did - although the early gen 3 is lethargic compared to the much better tech hemi, that cam really woke it up, even in the lower RPMs. My heads are getting milled about .010 and with the new pistons, I calculate I'll be almost 10:1, so for a budget build, I think I'm going to be pretty happy with it. Funny thing is used later model 5.7's really aren't that much more money now, but I already had the engine, so I'm using it. Great video!
Thank you for doing a Hemi video! If you ever feel inspired, I would love to see an early 235 HP Chrysler 4.7 with the infamous 2008+ factory cams and intake manifold swap! Rumor mill says they add power to the older engines but doesn’t seem anyone has done a dyno run after making those upgrades.
More head flow, good! More compression, good! How about putting the VVT back in the LY6 to show what goes on there? Of course this is a selfish question since I have one in my garage while working on rocker panels, etc. (typical ‘71 C10). I haven’t sprung for the cam yet, so this would be really good info. You’d have to tune it with the factory E38 and HP Tuners, probably keep the MAF, etc.
Hi Richard. I love your videos and have learned a lot from them. Based on your extensive knowledge and experience, will you please comment on the cause of lifter roller failures on Gen III hemis, and what can be done to cure/prevent the problem.
I am the original owner of a 2004 with the Magnum Hemi in it and currently have a 2017 with Hemi, both are SLT's, 2004 has 133k on it, 2017 has 48k, even at that big of difference in mileage, my money is on my 2004 lasting longer.
@@mattmurphy6157 there is a lot of evidence proving that the vvt 5.7 makes more power than advertised. If you look at dynos they make too much power at the rear wheels to be only making 370 ish hp.
Huge fan of Gen III Hemi!!! thank you - On a live video cast or posted video, you eluded to a future Mopar 360/5.9L Magnum test - when can we expect to see that?
Have any of you done a cam swap on a 2006 Dodge Ram 1500 hemi? Was it worth the investment? Tuning? Did you have to uograde the valve aprings? Would a 392 cam work this model year?
@@lopezcool976 the cam put me up to 402 hp and 403 tq to the wheels, but there’s some restriction there as my dyno curve completely flattens up top. My tuner was pretty sure it was the phase limiter. I’ll be replacing with a phaser lock soon here and re-dyno tuning to find out. My best quarter mile so far is a 13.2 (in 4100+ ft of DA, corrected to about a 12.5 ASL) with longtube headers and the cam as my only mods. My car is an M6.
Late model 5.7 truck intake manifold vs late model 6.4 truck intake manifold. Please. Love all the great content. Joined for the LS stuff stay for the variety.
Hi Richard, have you tested the Victor Edelbrock intake as well as the Edelbrock heads for the gen 3 hemi? I'm curious what the power difference would be from the OEM equipment.
Richard, can a late model dual-runner intake be put on an early engine? Getting more compression is pretty simple from early heads, but that dual runner is soooo interesting. Great video btw.
I have an 06 Hemi in a Jeep Grand Cherokee. Can you recommend a good cam that would increase power by 100hp plus give it a nice lopy idle. What other modifications would you recommend to go with the cam swap. The Jeep hasc120,000 miles on it. I have the 5.7 Hemi, 5 speed Quadratrak transmission with 373 gears.
You will never see under 4,000 at WOT except for about 40 feet of 1st gear and the little trade-off down low will make it easier to get the tires to hook and get the truck to 60'.
@@302hobronco yea. People worry too much about the torque loss little more aggressive gear youd never notice it. It makes such gains up top it is gonna feel faster and be faster with the aftermarket cam.
So, like I asked, serious question, if I run a hrt stage one cam, prior to boost with the hellion sleeper. Meaning not changing exhaust heads but adding piston and ring gap. .008?. Will that be safe till I add boost?
Are the lifters oil ported over the roller and needle bearings on the gen IV hemi, or is it the same problematic lifter designs as on the gen III hemi?
@Richard Holdener, if I have a 2006 charger rt and want to make that same power that your talking about, so i was wondering what would be the best cam set up to have. Thanks Dan
The Gen 3 Hemi and LS are really close in design, and have similar problems in the valvetrain. Unlike the LS, you have to pull the heads to do a cam swap....meh.....Im surprised no one has come out with a kit to swap the cams like the LS. Make life simpler.
@@hoost3056 Heads are totally different. Hemi has different valve layout, shaft rocker arms and dual plugs. You can change the cam without pulling heads if you don't change the lifters.
More gen 3 hemi stuff. Please

OEM hemi lifters are failing left and right, the shop I work at has been replacing cam and lifters in Ram trucks almost once a week, most have 80,000-120,000. The tiny local dealer stocks 6 cams, 96 lifters, and the parts guy says they sell at least one set every day over the counter, and two or three internal every day. I think I would consider aftermarket lifters if I was building one.
the reason that happens is because the cam is set very high in the block, so at an idle or low rpm the cam and lifters don't get much oil on them and they wear out. I wish dodge would wise up and put remote squirters or something over the cam to solve this problem.
Internal oiling is very poor to the camshaft. Needs to be kept at a reasonably high RPM to sling oil from the crank. Factory programming is absolutely for fuel economy, transmission will do its best to keep you in the highest gear possible for the longest period of time. Best bet is to limit the maximum gear, to keep the RPM's between 1,700 - 2,200 RPM at a minimum.
@@AmericaFirstKorey imagine "engineering an engine" so poorly, that typical driving kills valvetrain. Domestic auto manufacturers have thoroughly bought into planned obsolescence, and cheapening every item to the point where the vehicle is going to make it 100k and just self destruct.
@@jamesgeorge6551 absolutely sad, I run my 6.4 (2500) at 2,000 RPM typically, just manage the gear selection (which also disables MDS).
Great vid. I've got an early gen III hemi, but now I'm thinking I need to find a later Gen III...so thanks for that. With aftermarket fuel-injection for early engines become more commonplace, one wonders if we'll ever see a dual-runner composite intake for engines like the SBC/BBC's?
I'd like to see a Gen 1 Chrysler Hemi 331. They're so rare and unusual and heavy and expensive! I don't think I've ever seen anybody Dyno a street built one. Maybe even a commando 273!
Richard Holdener Quote of the day,
"That station wagon looking thing".
Never knew how valuable the intake was on my station wagon lookin thing lmao glad I kept it around
More late model vvt hemi stuff please cover the truck 6.4 and the car 6.4 and the differences in years that had a BGE block.
I wonder how the older hemi would do with the newer intake manifold
This is not confirmed but i got a few people talking about this:
The older gen3 bottom end was built much tougher than the latest gens which means less to upgrade if you want to boost them.
So ideally a gen3 5.7 with Magnum manifold and Eagle heads would the the perfect starting point for stupid numbers once you boost it.
Need to test the Holley mid-rise and a tall manifolds 👍🏼... Always good info thanks Richard
Unfortunatly for the cars the only dual lenght intake is the 6.4 srt manifold.
Got an 08 engine, last week, ordered that exact cam you used, glad I did - although the early gen 3 is lethargic compared to the much better tech hemi, that cam really woke it up, even in the lower RPMs. My heads are getting milled about .010 and with the new pistons, I calculate I'll be almost 10:1, so for a budget build, I think I'm going to be pretty happy with it. Funny thing is used later model 5.7's really aren't that much more money now, but I already had the engine, so I'm using it. Great video!
Did that camshaft end up giving your engine a chopped idle because of the lower LSA?
So in simple words. Cam change can upgrade 5.7 to SRT level
Faster bc to the wheel I think they make 360
This confirms that I really need to install my window switch to activate my runner valve in my hemi swap. 4900rpm it is.
Stock enable is 4800 fwiw.
Make sure you have the active runners.
can we see a intake test on the gen 3 hemi holley has some intakes and a brand new high ram vs ritter/dual plan
Thank you for doing a Hemi video! If you ever feel inspired, I would love to see an early 235 HP Chrysler 4.7 with the infamous 2008+ factory cams and intake manifold swap! Rumor mill says they add power to the older engines but doesn’t seem anyone has done a dyno run after making those upgrades.
Try putting the eagle cylinder head on the pre eagle engine
Big Bang a 6.2L Hemi.
That is an expensive big bang
sure would be
@@richardholdener1727 ...maybe a big bang 6.1 Hemi???
With a Hemi sometimes it tells you it needs a cam swap .. tick tick
More head flow, good! More compression, good! How about putting the VVT back in the LY6 to show what goes on there? Of course this is a selfish question since I have one in my garage while working on rocker panels, etc. (typical ‘71 C10). I haven’t sprung for the cam yet, so this would be really good info. You’d have to tune it with the factory E38 and HP Tuners, probably keep the MAF, etc.
Id be interested in this as well. I got an 08 suburban 2500 with the ly6. I've heard locking out the vvt is better but I don't believe that.
Hi Richard. I love your videos and have learned a lot from them. Based on your extensive knowledge and experience, will you please comment on the cause of lifter roller failures on Gen III hemis, and what can be done to cure/prevent the problem.
I have not had that happen
Boost em'! Let's see the results!
Good info...I have a 5th gen Ram with the Hemi and it's just as good as my 2011 Hemi was but with Etorque!
I am the original owner of a 2004 with the Magnum Hemi in it and currently have a 2017 with Hemi, both are SLT's, 2004 has 133k on it, 2017 has 48k, even at that big of difference in mileage, my money is on my 2004 lasting longer.
Looks like the the stock '17 hemi is best left alone. Torque is king on the street.
Perfect proof that these hemis are underrated from the factory.
I thought these were rated at 370hp and 395 ft lbs...is that not true?
@@mattmurphy6157 there is a lot of evidence proving that the vvt 5.7 makes more power than advertised. If you look at dynos they make too much power at the rear wheels to be only making 370 ish hp.
You can also buy this exact motor from Chrysler and they are rated at 383-395hp and 425 torque depending on where you look.
Or did it come out of a 2500? The reason I’m asking is because the 1500 has the MDS Cam and the 2500 doesn’t
Personally I blame squirrels
Well they do like to chew on engine wiring just ask my HEMI Ram .
Ya. I’d like to. Just can’t figure how they got inside my valve caver.
Did not check if anyone commented this. Can you confirm if 6.4 heads fit on 5.7 without any machine work? If not what work is required?
take a look at compression change
WOW! That was nice data right there..
Thank you again Richard.

THANK DAVID, STEVE AND STEVE FROM ENGINE MASTERS!
Huge fan of Gen III Hemi!!! thank you - On a live video cast or posted video, you eluded to a future Mopar 360/5.9L Magnum test - when can we expect to see that?
YES-ITS ON THE TO-DO LIST
I frikkin love your videos man. Good job.
So with an aftermarket cam it makes as much power as an LY6 with an LS9 cam.
Have any of you done a cam swap on a 2006 Dodge Ram 1500 hemi? Was it worth the investment? Tuning? Did you have to uograde the valve aprings? Would a 392 cam work this model year?
I'm not happy with the way my truck towes my 2015 Jayco 23rb travel trailer. Trailer weighs about 5k lbs and I tow at over 5k feet above sea level.
cams help, need springs and tuning
Never clicked on a video so fast! Haha. I agree, a cam really wakes up the 5.7. I put a comp cams hrt stage 2 in mine and it screams now!
Me to lol has a nice chop to it how much hp did u gain and whats your 1/4 mile
@@lopezcool976 the cam put me up to 402 hp and 403 tq to the wheels, but there’s some restriction there as my dyno curve completely flattens up top. My tuner was pretty sure it was the phase limiter. I’ll be replacing with a phaser lock soon here and re-dyno tuning to find out. My best quarter mile so far is a 13.2 (in 4100+ ft of DA, corrected to about a 12.5 ASL) with longtube headers and the cam as my only mods. My car is an M6.
What springs you guys running
@@TrackPackRT dammn sounds good sounds like its very strong
@@hankautomotive mine are the springs that came in the kit from comp cams. Don’t recall the specs.
Thats it, my mind is made up! My 2017 WK2 5.7 Hemi. What is the recommended Performance Cam? Texas?
I'm curious if there's a difference in deck height on the 17 vs the 06 hemi.
Idk but my 2017 Ram 🐏 got some power for a big truck 🙌🏾💪🏽💯that’s enough for me! I’m not racing or nothing!
Late model 5.7 truck intake manifold vs late model 6.4 truck intake manifold. Please. Love all the great content. Joined for the LS stuff stay for the variety.
The 6.4 truck intake is best the 5.7 truck and 6.4 car are about equal.
So a comp vvt cam I could make those gainz? Adding a pair of longtube headers like kooks? What can of power am I adding to my charger ....?
Hi Richard, have you tested the Victor Edelbrock intake as well as the Edelbrock heads for the gen 3 hemi? I'm curious what the power difference would be from the OEM equipment.
NO SIR
Richard, can a late model dual-runner intake be put on an early engine? Getting more compression is pretty simple from early heads, but that dual runner is soooo interesting. Great video btw.
not sure on port and mounting hole fitment
I have an 06 Hemi in a Jeep Grand Cherokee. Can you recommend a good cam that would increase power by 100hp plus give it a nice lopy idle. What other modifications would you recommend to go with the cam swap. The Jeep hasc120,000 miles on it. I have the 5.7 Hemi, 5 speed Quadratrak transmission with 373 gears.
You might want to upgrade the valve seats before they fall out like mine did
100 horse!?!?....O you will definitely have a VERY CHOPPY LOPE😂😂😂🤣
@@captainobvious5993 what did you upgrade to? My car has 180k not sure if previous owner already changed valves should I change them?
@@H1storybr3akdown just disable the mds system and after highway travel let it idle for 30 seconds before shutting it down
@@captainobvious5993 how do I disable mds on an 06 Jeep Grand Cherokee with the 5.7, I can’t find a tuner
Based on your (Freiburger's) results; I'd rather have the stock cam.
You will run ALOT slower with the stock cam, especially in an 8spd truck shifting around 6,800.
You will never see under 4,000 at WOT except for about 40 feet of 1st gear and the little trade-off down low will make it easier to get the tires to hook and get the truck to 60'.
Wouldn't gears make up for the loss of torque?
@@302hobronco yea. People worry too much about the torque loss little more aggressive gear youd never notice it. It makes such gains up top it is gonna feel faster and be faster with the aftermarket cam.

Enjoying my HHP Stage 2R in a WK1 SRT8
How about a 5.7 hemi vs 5.7 LS shootout?
This is almost like an instructional video as to why non one wants this motor if they have any sense.
The one in the corvette or the one in the camaro?
I really want you to test a 5.7 with the 6.4 cam, and then the 6.4 cam and intake.
This is weirdly intriguing....
Thanks for the info.
how about a 6.4 intake and cam on the vvt 5.7? It should allow for full vvt travel that way.
So, like I asked, serious question, if I run a hrt stage one cam, prior to boost with the hellion sleeper. Meaning not changing exhaust heads but adding piston and ring gap. .008?. Will that be safe till I add boost?
Hey Rich you still got that cam for sale he know it's been several months ❓🚩💰
The 5.7 is a great, bullet proof engine but it's time it gets a horsepower bump. Let's see 405hp 425lb ft tq, and bump the 6.4 up to 515hp.
They could do that but it would hurt reliability in a truck.
Are the lifters oil ported over the roller and needle bearings on the gen IV hemi, or is it the same problematic lifter designs as on the gen III hemi?
@Richard Holdener, if I have a 2006 charger rt and want to make that same power that your talking about, so i was wondering what would be the best cam set up to have. Thanks Dan
ported heads and cam(the new lst cams work well)
Over 500hp out of a 5.7 is pretty impressive. Is the cam swap on these as simple as an LS?
The Gen 3 Hemi and LS are really close in design, and have similar problems in the valvetrain.
Unlike the LS, you have to pull the heads to do a cam swap....meh.....Im surprised no one has come out with a kit to swap the cams like the LS. Make life simpler.
No need to pull the heads to swap a cam in the newer hemis either. Done then multuple times without pulling the heads.
@@hoost3056 Heads are totally different. Hemi has different valve layout, shaft rocker arms and dual plugs. You can change the cam without pulling heads if you don't change the lifters.
yep-with good trays (even better angle than LS for staying put)

I agree, everyone puts chevy engines in everything else. How about switching it up and put something other than a gm engine in the nova.
