1. COMP Cams 12-242-2 Xtreme Energy 224/230 Hydraulic Flat Cam 

COMP Cams 12-242-2
COMP Cams 12-242-2 - Best Cam for Chevy 350 4x4
4.6
Grab the COMP Cams 12-242-2 Xtreme Energy cam for high-powered open-road service. According to its intended street use, this cam ticks all the right boxes regarding duration, LSA, and hydraulic mechanism.

COMP Cams 12-242-2 Xtreme Energy is the ideal pick for street performance vehicles. It boasts the latest cam technology with quicker opening lobe profiles that increase responsiveness. The aggressive lobe profile also provides excellent top-end horsepower and throttle response.

This cam has its torque curve and peak power in the 1,600 to 5,800 RPM range. While you won’t miss the high side of 5,500 RPM, this cam’s more vacuum offers a step up in duration without sacrificing creature comforts or drivability. 

COMP Cams 12-242-2 also delivers adequate vacuum for the power brakes and accessories. You may want to pair it with lower gear ratios, aftermarket intake manifolds, headers, and free-flowing exhaust. These parts allow it to breathe well since it can handle more airflow. 

Being a hydraulic flat cam, you’ll like that it does not suffer from slow acceleration off its seat, but the trade-off is slower ramp acceleration. Nonetheless, the overlap is less due to the duration and 110° lobe separation, so it will not result in a rumpy-rump-rump idle. 

The hydraulic mechanism and the low RPM range are good combinations that prevent insufficient spring control and deflection in the valvetrain, among other instabilities. Overall, it’s an excellent option for a stock 350, and it produces just enough horsepower for the street runner.

Pros

  • Smooth idle
  • Offered in four variations 
  • Good for daily use 
  • Sufficient vacuum for braking
  • Smooth power and response

Cons

  • No assembly lubricant
  • Isolated complaint about receiving a used cam

Grab the COMP Cams 12-242-2 Xtreme Energy cam for high-powered open-road service. According to its intended street use, this cam ticks all the right boxes regarding duration, LSA, and hydraulic mechanism.

2. COMP Cams CL12-212-12 Magnum 224/224 Hydraulic Flat Cam 

COMP Cams CL12-212-2
COMP Cams CL12-212-2 - Street Cam for Small Block Chevy
4.6
COMP Cams CL12-212-12 Magnum is for those that wants a beast of a car without worrying about getting beat at a traffic light.

Here’s another cam for street performance, but it’s made to operate at higher RPMs. The COMP Cams CL12-212-12 Magnum boasts 230/230 durations at .050 inches. The wide 110 degrees lobe separation angle means that the intake and exhaust open later, so the cam does not exhibit a nasty idle with more lope. 

Thanks to the high RPM range between 2,000 and 6,000 RPM, the Magnum CL12-212-2 is easy on the valve train parts. You can also use it with conventional performance valve springs and mild ratio rocker arms. It needs at least 9.5:1 compression available in most Gen 1 small-block Chevys. 

Nevertheless, this hydraulic flat cam idles rough and sometimes affects power accessories. It is the largest cam you can use with air conditioning and power-assisted brakes. In addition, it needs a 2500-stall converter, but a 3000 is recommended. Most stock components are incompatible, so you’ll also need headers and rear end gear ratios. 

When using it in the Chevy small-block engine, you need to add a vacuum canister because of your power accessories. Otherwise, this cam can hit the race tracks on weekends or be driven heavily on the street. 

Pros

  • Perfect for street machines 
  • Adds up to 48 hp and 20 lb.-ft torque 
  • Broad, usable power curve 
  • Aggressive profile for max top-end performance 
  • Includes with a lifter kit

Cons

  • Only a tiny amount of lube in the package 
  • low ramp rates for casual races

COMP Cams CL12-212-12 Magnum is for those that want a beast of a car without worrying about getting beat at a traffic light. It gives you street-ability while also providing you more power to punch it on the weekends.

4.4
COMP Cams 12-600-8 is an excellent pick for tremendous high-performance sound. It’s rated for street/strip applications, and the hard-hitting exhaust note is sure to turn heads whenever you punch it.

From the Thumpr line, you will like the COMP Cams 12-600-8 if you want authentic high-performance engine sound. The lobe separation on this cam is tighter to create more overlap between the intake and exhaust vents; thus, you get the cool performance sound. 

This cam is a hydraulic roller type that you can use in an engine that originally used a flat tappet camshaft. It delivers considerable power increase over identical hydraulic flat tappet cams. All the while, it does not compromise ease of maintenance or reliability. 

This cam boasts a comfortable low-end response with the lobe separation at 107 degrees and the intake centerline at 102 degrees. At the same time, the early opening of the exhaust and long exhaust duration provide significant gains in torque and horsepower.  

This cam operates at the 1,900 to 5,600 RPM range. This range allows you to enhance the power and the torque at the highest. It’s designed to work at a high compression ratio of 9:1 to eliminate the chance of incomplete combustion, which means that you’ll need less fuel than you did to cover the same number of miles. 

The COMP Cams 12-600-8 offers a 0.511/0.497 valve lift which comes in handy to help the engine get a rich air supply. It helps your exhaust get loud as it boosts your engine needs. 

Pros

  • Produces good power and torque 
  • High-performance sound
  • Wild camshaft idle
  • Opens valves for longer

Cons

  • Costly than flat-tappet configuration cams
  • Lumpy idle is not for everyone 

COMP Cams 12-600-8 is an excellent pick for tremendous high-performance sound. It’s rated for street/strip applications, and the hard-hitting exhaust note is sure to turn heads whenever you punch it.

Pros

  • Excellent street and towing performance
  • Considerably cheaper than most OEM replacements 
  • Increases horsepower output 
  • Reduces acceleration delay

  • Only a small number of compatible engines 
  • Lubricant is runny instead of a thick paste

COMP Cams 12-602-4 Big Mutha’ Thumpr means improved performance and incredible RPM range for street and muscle cars. The cam enjoys broad compatibility, so it’s likely the right size for any small-block Chevy.

For the fan of a rough idle, and aggressive sound, you will like the COMP Cams 12-602-4 Big Mutha’ Thumpr. All you need is to combine this cam with the right muffler and carburetor, and you have a part to beat in your muscle or drag race car.

This cam’s RPM reaches 6,400, greatly improving your engine’s horsepower. It does not suffer from incomplete combustion thanks to its 9.5:1 compression ratio. Furthermore, it has a wide lobe separation at 107 degrees to provide ample room for fuel intake. The cam extends the exhaust’s duration to prevent detonation in the low-to-mid-range. 

The actual duration at .050″ measures 243/257, which is preferable. Further, the valve lift is 0.5″/0.486 to provide lots of air supply and cleaner combustion. You will be driving further with this cam than you would on your stock parts. 

Nevertheless, this cam requires a 2,800+ stall converter, gears, headers, and intake. Also, include valve springs that can handle the lift since your stock springs probably won’t take the increased output. 

Meanwhile, you can expect a noticeable increase in your car’s horsepower and torque once you install this cam. It also provides extended durability owing to its cast-iron construction, and hence, it can take on a beating even in long races. 

Pros

  • Available as a kit with lifters 
  • Impressive value for money
  • No incomplete combustion
  • Increases torque curve and horsepower
  • Good fuel intake 

Cons
