Newcomer Racing Cams come in many different custom grinds to suit your specific needs. We've ran every single one of these grinds and many more over the years to find the best of the best. We decided put together a list of our favorite cam grinds and offer them to the public. Picking your favorite cam can sometimes be a daunting process, so we have added descriptions to each cam profile to help aid in your decision.


Basic things to consider when choosing your cam:


  • RPM range and where you want your powerband.
  • Application(Daily Driver/Off-road/Racing/Multi-purpose)
  • Weight
  • Transmission(Manual or Auto)
  • Gearing
  • Engine Size
  • Compression
  • Induction/Exhaust(Stock or Modified)
  • Exhaust Tone vs Engine Smoothness at idle.


***All of our AMC/Jeep cams are Hydraulic Flat Tappet(HFT) or Mechanical Flat Tappet(MFT), "Roller IS NOT AN OPTION". Lifter options are Hydraulic/Mechanical w/EDM hole. Our cam grind part numbers will indicate the recommended lifter style although you can run a mechanical/EDM lifter on any of our cams.

Some of our smaller grinds are No Springs Required(NSR) which means you can run your stock springs but always check for coil bind. Stock spring specs are normally around 50-60lbs on the seat and 200-220 range open and good for around .460" lift. For upgrade spring rates you will need to target 90-115 seat and 260-300 open pressures.

All of our cam spec numbers are based on a stock 1.6 rocker ratio. If you go to an upgraded 1.7 rocker ratio this will inherently raise your total lift values, so be aware when choosing for your springs max lift values. All cams and lifters are thoroughly inspected, cam journals are micro-polished, cleaned, oiled and ready for installation with assembly lube.

On any of our cam kits or anyone else's for that matter, do yourself a favor and degree your cam, this will save you dividends in the end, trust us! Every single stock motor can benefit greatly from just a proper custom computer tune, we have done it, so we recommend custom tuning to maximize all that work and money invested to increase your usable power.

When other companies say no tuning required to get your sale, don't believe it, yes it will run, but no it will not be nearly as efficient. From the smallest cam to the biggest, the more you do to enhance the efficiency, from induction, exhaust or the rotating assembly on your setup, the better it will perform. This multiples and becomes more important as you go up in cam size.

After deciding on your choice of camshaft, choice your add on's to complete your cam kit.


  • NR-120-HFT-NSR(207/211 112 .459"/.461") Powerband Idle-5,200rpm's with a deep smooth idle quality, great stock cam replacement upgrade that works with a stock stall converter and all stock components that can make great small quick spooling turbo or supercharger cam. "Mr. Smooth"
  • NR-121-HFT-NSR(212/216 110 .460"/.460") Powerband 1,200-5,500rpm's with a noticeable deep idle quality, the most aggressive cam we recommend using with stock springs. Works well with all stock vehicle components, with upgrades just keeps showing gains. "300HP"
  • NR-122-HFT (213/217 112 .480"/.494") Powerband 1,300-5,600rpm's with a noticeable deep idle quality, this is the first step up the ladder that requires a spring with more lift capabilities. This makes a great entry level cam combo with our competition head for those who want to utilize added lift, with our 1.7 roller rockers you will net .510"/.525", works with stock stall converter. "Lightning".
  • NR-123-HFT (214/211 114 .478"/.461") Powerband 1,200-5,400rpm's this is the weird cam profile of the bunch but don't let that fool you this little guy works awesome with a wide power band. This profile works well on any application and gives plenty of intake cylinder filling with the added duration. Stock short block or lower compression for low octane usage this is your cam. Works well with stock stall, increased lift springs required. "Odd Ball"
  • NR-124-HFT (214/214 113 .478"/.478") Powerband 1,200-5,600rpm's this little guy is a great all around cam for naturally aspirated or forced induction combos. We have tested this one extensively in the "Mutt" 4.0 motor on the engine dyno(326hp/343tq on boost 550whp/600whp), on street, towing and racing. At a stock idle this cam will have a slight deep lope, increased spring rate and added clearance required. Works with stock stall converter. "Mutt"
  • NR-125-HFT (218/224 112 .494"/.504") Powerband 1,500-5,900rpm's this one will have a slight aggressive lope at stock idle. Now your starting to get up in the cam area where induction and exhaust upgrades will start to become options to utilize the benefits of this cam. We have ran this cam profile for 15+ years and made killer power numbers in daily drivers to all out race rigs. This is a great starter in the aggressive cams yet yields great driving manners and yet you can twist that tach to 6,000 rpm's. We recommend both HFT and MFT lifters depending on your application. We machine our blocks for direct cam oiling for HFT and MFT setups. If you want to utilize direct cam oiling on your stock blocks and have adjustable roller rockers then you can select the MFT-EDM lifter with a direct feed hole to help with wear and higher rpm control issues. Still works with a stock stall but with a 2,000-2,400 stall you will benefit. "Old Faithful"
  • NR-126-HFT (220/226 112 .528"/.536") Powerband 1,600-6,200rpm's now we are getting somewhere. This cam needs head, induction and exhaust upgrades to serve it well with more compression or forced induction this thing rips. We have made well over 400+hp with this cam with a built stroker. You can run a HFT but we recommend a MFT-EDM lifter to avoid wear and upper rpm control. This one lopes without a doubt and with a 1.7 rocker it pumps out .561"/.570" lift. "Bump and Grind"
  • NR-127-HFT (226/232 110 .520"/.568") Powerband 2,000-6,200rpm's if you want to get noticed or hated this is your cam. With surprisingly great driving manners this cam with turn heads at the stop light with a healthy lopey idle quality. You can still run a HFT but we recommend MFT-EDM for longevity and upper rpm valve train control. This one will need all the induction upgrades along with a 2,500 stall, manuals let it rip! With a 1.7 roller rocker this one pumps out .552"/.604" lift so have your build with induction and exhaust upgrades on point and raise that idle to 750rpm's. "350HP"
  • NR-128-HFT (228/228 113 .509"/.509") Powerband 1,800-6,200rpm's this mid sized powerhouse single pattern cam will make some noise, the good kind. An all around great performance cam for NA and boosted applications. Get your build on point to reap the benefits or simply throw the boost at it for an aggressive daily driver and set that idle to 750rpm's. "Boosted"
  • NR-129-MFT (236/236 113 .540"/540"). Powerband 2,300-6,400rpm's dual purpose single pattern powerhouse. If you want that aggressive chop at idle with your NA build or forced induction, this one fits the bill. For forced induction cam this top of the ladder for a daily driver/street machine. "Maniac"
  • NR-130-MFT (236/244 110 .540"/.563") Powerband 2,400-6,400rpm's now business is picking up. This can be a street/race cam with a very healthy lopey idle, no mistaking this bad boy is made to be seen. Stock idle will need to be raised to at least 800rpm's for a nice crisp pop out the tail pipe. With a 1.7 roller rocker this one hits .574"/.598" on lift, 2,600-3,000 stall required. "Street Terror"
  • NR-131-MFT (244/252 108 .544"/.544") Powerband 2,800-6,600rpm's talk about a noise maker this one fits the bill, straight up race or hard core street machine if you dare. If you have never heard a built inline with a nasty cam trust us they sound amazing, similar to a BBC if using a 6 to 1 header. This one is made for naturally aspirated applications where compression will be your friend. 3,000 stall required, or sticks, grab a good clutch and give it hell. "McNasty"
  • NR-132-MFT (264/272 106 .594"/.598") Powerband 3,400-7,200rpm's all out race only here unless you want to be a total badass on the street. This one needs compression, flow and some great parts so this thing can spin to 7,000+rpm's. A Jeep/AMC motor changes tones around 6,000 rpm's, the kinda tone that makes the hair stand up on your neck. Well, this one goes way past that point so hold on to your seat. With all the supporting mods this cam will make 500hp NA and make people cringe at the wicked snap crackle pop sound. Make sure you run a fully counter weighted crank at these rpm's. "Widow Maker"


***Tech tip for customers wanting to go with a more aggressive camshaft. To run a larger style camshaft that will turn over 5,500 rpm's you will absolutely need a spring upgrade and do not forget about your harmonic balancer. Our ATI balancer will become a key component to achieve harmonic control of your in-liner. If you do not address this area it will absolutely create problems in trying to run higher rpm's.
