Who does the best 392 cams?

40753 Views 65 Replies 19 Participants Last post by  crystalblue_392
There's a lot of companies offering cams for the 392 Hemi, but it's hard to know who to choose. B Mason from YouTube has a cam that's offered through Peitz Performance. David Weber from MMX makes cams. HHP offers them. Comp Cams makes a stage 2 HRT kit that's supposed to be an excellent shelf grind that offers an 80hp gain from the cam alone. Texas Speed just started doing gen 3 Hemi cams. Jannetty Racing and Jay Greene do cams.

Who the hell do I go with??

I'm not looking so much for peak numbers, but for reduced 0-60's, more torque in the mid to high RPM range, minimal loss of low end torque and throttle response, and max possible gains throughout the entire power band, while maintaining good everyday drivability and not requiring a torque converter. I'm not even looking for an insane "chop." I don't care if its an NSR cam or not, I'm planning to pull the heads to upgrade the springs and delete the MDS hardware anyway.

It seems the two biggest companies in cams for the 392 are MMX and HHP. Anyone had experience with their cams?

Lol, makes me thankful I'm not married yet, all my girlfriend can do is scold or look at me disapprovingly.
Just tell her something broke or you're replacing it as preventative maintenance. My girlfriend doesn't know about my supercharger yet

Lol the right girl will eventually accept who you are. My wife has entered that territory and I have her right where I want her. 😂 She supports what I love and that’s what it should be.

Hahahaha this guy hid a 8K mod, that’s insane. “Honey, is your car way faster? Also what’s that whistling/whining sound?”

“Nothing babe, it’s just the wind and I’m pressing the pedal harder.”

Have you priced a cam swap and a tune? Are you capable of doing the work yourself?
Got a quote today from our friends in Mansfield, $1950-2100 to install cam/lifters, headers, and stall converter. I think that's very reasonable. I would not attempt this install w/o a lift.

It will likely be 2mos before all the parts arrive, namely the Stainless Works headers. I'm leaning towards the MMX Max Effort cam.

Pay the cash and have the headers ceramic coated. Save yourself some headache with underhood temperatures.

Yep, that's in my plans. Was surprised the headers are backed up that much (2-3mos!). Circle D converter about 3 weeks backlog.

People also say the coating doesn’t last so save your money.

I’m scheduled to drop off my 1320 with MMX in early July (earliest they could do it) for install of headers, a custom grind based on the Max Effort cam (the core is Cam Motion), springs, lifters, rods, the Zauto SRV Controller and two tunes (Street and Race).

I chose to go with MMX and their Max Effort (as a base for the custom grind) based on the detailed conversations I had with a Cam Motion tech and the engine builder at MMX. While all the technical aspects of choosing a cam are second nature to them, it’s all new to me and both gents went out of their way to walk me through the process, answer my questions, and ask detailed ones of their own to make sue all sides were on the same page in terms of objectives and desired results.

Not saying other shops don’t provide this level of service, but of all the shops & cam companies I contacted, this combo impressed me the most.

Two separate shops, both widely known and respected, said to save my money and not coat my headers. One claimed never to have installed coated headers; both install and tune, but saw no need nor benefit.

Oh man your 1320 is gonna be awesome. I made the mistake of not going to a shop that can do the cam (mmx ME) install and tune. I ended up going thru 3 tuners, and 3mos later the dyno results are unimpressive. I'm tired of these so-called experts, I'm going to tune it myself going forward. Check my IG: 4_shaken for details

If you got the time and money I'd do the ceramic coating on the headers for sure.
The header coating doesn’t last that long from what I have heard so if they are telling you to skip it they are probably being honest.

In April 2021, I installed the MMX Max Effort NA cam in my '16 Scat Pack Shaker

this required new springs, lifters (req'd for warranty on cam), unlock PCM, buying tuner (HP Tuner) & 2 credits, and a remote tune from MMX as well as the cam, gaskets. I upgraded the pushrods as well. The MMX kit included the spring locators, shims.

My initial dyno (with email tune) seems low - so I'm going to have dyno tuning done by a local outfit that did my friends SRT 392 back in 2018 (with the MMX NSR cam). The version I have (MAX Effort N.A.) has higher lift than the NSR version

one observation on the lifters - mine is an M6 I had the 787AA version (build Aug '15) of the lifter and the current version is 787AD (Aug '19 build) the roller tip bearings look the same size between the old and current version.
-in the images the one with the dimple in the axle is the AA version from 2015...

Sounds like we have similar build and results. I have the same kit, plus hellcat TB, and lt headers. Mine dyno'd at 477hp on day1 and 475hp / 480tq on day2. Research shows that mmx me cam typically gets above 490 hp.

My dyno (this facility installed theirs last year) and the IATs were in the 100* range - was 448 rwhp / 463 torque which is low.

The outfit I'm having the additional tuning works on a lot of different makes, but they're pretty much THE guys to go for tuning Hemi engines (and they build for customers as well) - so we'll see what baseline values they have and they're looking at their database of previous customers to see what results they got with whatever mods with the MMX ME N.A. cam...

I went with the comp cam 270. Most people going comp cam go 270 or 274. The 274 is a beast to tune. The 270 Offers mid range power gain whereas the 274 offers the gain at a tad bit higher RPMs. The folks above are correct, It was expensive to do with lifters, push rods, mds delete, phase limiter etc. however, it pays off when you think of it as staging. The final product will all add up. Hit me up if you want more info, I have sent a couple of guys my setup with everything you need on an 8 speed 392 cam swap. Part numbers and what it runs about around here in Chicago. If you can do yourself you will save a lot of money. As far as reliability etc it really comes down to the tuner. Again it’s a lot of money for the gain alone but if you think of it as staging it’ll be worth it at the end and the sound is amazing, def not like an old school muscle car but the lope is there.
Hey man you think you could send me that list? I’m a GM guy but my Lady bought a challenger and we would like to make some upgrades. Thanks

I’m with you on having something you put together. I love feeling the change in stages. First thing I did was long tubes catted midpipe and first tune. Which as you know that first tune is pricey, getting the pcm unlocked etc. then I went cam springs lifters push rods and second tune. It’s nice feeling the difference in between stages. At least I like it. Others like it all out the box and that’s totally cool as well. Whatever your preference is, is the way to go. You get to make it your own. Your right I’ve read a lot about the stock heads and many people say the stock ones are impressive.
I’m looking into a stroker kit, ran into a guy with a 426 and wow was that impressive. He also had a pro charger though. He said that was the last thing he did. Have to admit that 426 along with the winding from the sc was so nice. These cars are pretty well built from factory, tons of owners just add the sc and are done with it and it’s still pretty impressive. That’s why I like this forum, you have guys doing all sorts of stuff. Fun to read and keep up with.
Is it possible to just “add a SC and be done with it” and still be able to safely drive it? I’ve heard anything over 6-7 psi or anything over 600 crank HP you’re gonna run in to real problems with the cars internals still being stock. I’ve read yalls convo so far and I’m buying a second car soon within a month or so. sometime this year(hopefully! if I get the balls to kill the warranty since it’s a brand new car, a 2022 with 12k miles🙃) I’m gonna start building my scat, long tubes, air intake, catless midpipe, cam, lifters, springs, rods and alla that. I think a SC would be last for me. When do you suggest getting that first tune? After just the midpipe and headers? Or where should I even start? I’m new to all of this and am still learning a lot. I really want the gains that come with a good cam and good tune first though. So maybe cam, springs and long tubes with a tune an then go from there? Long question, sorry.

Is it possible for you to send me a list of that somehow? I’m curious on which mods are best to do first and after which mods/when it’s best to throw the first tune on it. I’m new so I’m still learning a lot and idk i can’t figure out how to send private messages on here or I would. I’m wondering what’s the best order to do all of these mods with the tunes. Mines a 2022 scat pack so I’m not gonna do it until later this year (maybe depending on if I get the balls to kill the warranties I have on it🙃) so any help would be great man thank you. I want basically the most Hp possible (reasonably) while still being able to drive it around however hard I want to on the weekends (not as a daily) and not have to worry too much about breaking ****.

That’s awesome man. I’ve read good things on the mmx cams. I’d double check the hp gain though just so your not disappointed. Most dyno numbers show around 35 to maybe 60hp to the wheels gain on a cam swap alone. There are several threads on here with numbers and some good videos on YouTube regarding actual gain from a cam swap. The range seems to come from tuning, and maximizing while maintaining safe function. Whoever you decide to go with I’m sure it will be awesome. Look forward to hearing what route you went. Best of luck.
I have max effort cam and I made 485/49
I am also on a similar path with my 2019 5.7. I spoke with a shop today and got a print out on price and what parts I would be changing (see my most recent post for more details). A cam is the only thing I am not sure about. Keep in touch on what you decide to go with, what you describe is the same thing im looking fod in my 5.7

Good luck

please forgive me, for I am new to this forum and not sure if I’m replying in the right spot , I have the modern muscle extreme max effort cam, I replaced all the springs, the lifters rods, retainers came with phase limiter, got rid of the MDS, put in a torque converter, long tube headers JLT cold air intake, ATI 15% under drive pulley, 180° thermostat, ported throttlebody, ported intake manifold, catless mid pipes, custom drop in fuel pumps and an E 85 pro flex system and obviously the nitrous which I spray 120 shot. On 93 octane NA, it made 504/500. On e85 na it made 520/515.

Whats your run without no2? If you checked it. Is it 500 minutes 120? Not sure how no2 shots work
