GEN-3 HEMI CAM TESTS-2017 VS 2006 

Thought someone would catch that

Glad I’m not the only one that snorted when I heard that lol

When an expert tells you "more head is always a good idea" you take his advice.

I would wear that shirt

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.

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

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

@@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.

Cos he is too busy working

No way 😭😭

Tell your son when we landed on this planet I took one big breathe and have not let it all out yet!

No time for breathing...more testing😉

@@richardholdener1727 Lol 😆. Reminds me of the first predator movie. I don’t have time bleed 🩸. Got time to duck. Thooomp. Booom !!

How much was it, would like to do something like that

Dale mullens where are you located in Alabama I’m trying to get a cam installed on my 6.1 and can’t find anyone to work on hemi

Can I hire you to work on my 5.7

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

I've had the mic for a year now

Same I want to do more to my scatty automatty

Need any parts? I got some used 5.7 stuff laying around

I love my 6.1 hemi, it's very reliable, I pushed it to 160MPH and it still wanted more😅👌

I have the specs of the 6.1 cam according to the srt engineers

I thought the Durango is a rated for 360hp. If this video is right it makes a good deal more than the rating

@@corruption1724 it is 360 but that's threw the stock exhaust and factory air box with a very conservative tune

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

The 6.4 truck intake is best the 5.7 truck and 6.4 car are about equal.

Lol, maybe... If all you plan on doing with it is drag race... But in that case, anyone with a real race setup will still blow your doors off.

@@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 ****...

Good stuff, can probably go with something with a bit more lift, that cam is pretty mild, only 510 lift

it was rated at a similar power-not sure what testing actually shows

is it that common ? I remember a collegue that had to rebuild clients 5.7 twice, that was quite a mystery.

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.

THANK DAVID, STEVE AND STEVE FROM ENGINE MASTERS!

This test uses the eagle truck 5.7 manifold which is functionally identical to the car 6.4 intake.

Never knew how valuable the intake was on my station wagon lookin thing lmao glad I kept it around

That is an expensive big bang

sure would be

@@richardholdener1727 ...maybe a big bang 6.1 Hemi???

My 06 Ram was 285/301 on a Dynojet with long tubes, dual 2.5" exhaust with a X-pipe and stock tune.

YES-ITS ON THE TO-DO LIST

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.

Sniper?

@@homefront3162 holley released the hi ram for the hemi recently

Excuse me do you know if a 2012 hemi engine can fit on 2007 chrysler 300c with the same PCM or ECM? thanks in advance

@@homeroaguilar6163 it won't.

@@UnionThugg Thank you, I guess I will try the viper engine with transmission from a dodge ram

@H. Bailbondsch Variable Valve Technology used in 2009+ V8, basically advances valve timing

@H. Bailbondsch It's Variable Valve Timing

Stock enable is 4800 fwiw.

Make sure you have the active runners.

Faster bc to the wheel I think they make 360

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.

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.

I have not had that happen

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.

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.

@@midnight347 BS.

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.

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.

@@jasonwalls1277 Blasphemi is a tri5 with a hemi, think he just blew another one up.

@@bradmaas6875 yeah, he did.

You want it to sound like a 69 F100??

@@stevebates5973 What's wrong with a '69 F100?

not sure on port and mounting hole fitment

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).

the 2017 belong to them

They could do that but it would hurt reliability in a truck.

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)
