[@mynameisjosh4506]

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!

[@ERidParasoth]

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]

the factory 392 cam has a 220/230 duration split-just checked-stock 392 hemi cam is smaller in both lift and duration and lobe intensity

[@IntenseBlue318]

@@richardholdener1727 think you've also got different cams in the truck and cars (and auto vs stick).

[@ERidParasoth]

@@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.

[@jessemurray1757]

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.

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.

[@jaymoe5.7]

@@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.

[@Ed70Nova427]

@@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.

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)?

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

[@The3chordwonder]

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!

[@kendrick6387]

Did that camshaft end up giving your engine a chopped idle because of the lower LSA?

[@kma4444]

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 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.

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.

[@Ed70Nova427]

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.

[@AircraftMechanic-AP]

Hemi is a beast.

[@bdugle1]

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.

I think I would consider aftermarket lifters if I was building one.

[@jaymoe5.7]

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.

[@AmericaFirstKorey]

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.

@@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.

[@richardholdener1727]

yep-with good trays (even better angle than LS for staying put)

[@dodgesportsman772]

2013 hemi.... Late or early? I also have the lifter tick.... And diy videos on camshaft replacement?

[@richardholdener1727]

that is late

[@lloyddecker2965]

Ok so with the late 5.7 hemi they put a stop on the cam from advancing ? So that would mean the late and early 5.7 are the same ? Only the difference is compression and heads and intake correct ? So put the early heads intake on a late 5 .7 should make the same yes ? Because the vvt is set to one point ? Just wondering

[@richardholdener1727]

the VVT was active in stock trim-they only put the limiters in place during the cam swap-there was still minor VVT movement

[@lulujrlaulom7905]

great vid.. Good stuff.

[@brucebeamer2298]

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?

[@td8113]

I'm curious if there's a difference in deck height on the 17 vs the 06 hemi.

[@alexzgolak8820]

Alright, now test the holley hi ram for the hemi.

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

[@98dodge360v8]

Unfortunatly for the cars the only dual lenght intake is the 6.4 srt manifold.

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😂😂😂🤣

How much ignition timing were you running up top on the 2017? The thing maintained power at 6k better than I expected.
