Comp Cams SBC Xtreme Energy Hydraulic Rulle Knastaksler.
These special lugs are made of an isothermally hardened ductile iron core (super-hardened cast core) and have a reduced base circle (1.050). This allows most rods on the market to be used without having to grind any material off of them when used on 3750 stroke crank motors such as the 383 and 406 sbc engines including Scat H-beam bars which tend to have the worst camera interference in the roots. The 421 pitch (3875) cranks required very little grinding, and depending on the type of bar, you may not need to grind them. This not only preserves the integrity of the rod, but most importantly, the bolt of the rod. By not having to grind the bars, you will also keep the rotating unit balanced if it has already been balanced before removing the bar cams. We now use these downsized base wheel cams in every sbc motor we build. These special cams can be used with a regular transmission gear. No need to run the bronze gear. The length of the follower is typically approx. 0.050 longer than what the solid base circle cam uses due to the reduced base of this cam.
Take a look at what needs to be done to the rod body and bolt section of this rod in the photo below when using a full circle cam at 3.750 pitch(383 or 406)engine. The thought of having to go that far into the screw is disturbing to say the least. The reduced base wheel cam eliminates the need to do this. As mentioned above, this is one of the many reasons why we now use reduced base cams on all our sbc engines.
An important note from our CEO, Skip White.
Our new Comp line of custom street rod cams have improved our horsepower and torque better than anything else we've done with our range of street rod motors. The profiles of these performances are unique. Increased hp by around 20-30 without increasing lift and duration or laps Sep. compared to our previous series of cameras. As time goes on we will be adding many dyno reports with various intake and rocker arm ratio combinations, showing this cam being used on engines ranging from 383 cubic inches all the way up to our 434 gas pump engines. These ads will show you the camera's many features and operation, as well as our recommendations on what to expect in terms of street behavior.
We are often asked about the RPM range of a given cam as indicated on the cam card. In our opinion, this information is useless. These RPM ranges can be very confusing. It would be fair to say that 99.9% of people misinterpret these numbers. If we asked 20 different people what "area of operation" meant, they would most likely come up with a different explanation. Also, most people don't realize that the size of the motor will drastically change the operating range, and if you understand that, you still have to wonder what operating range really means.
Many camera tabs also list camera uses and features, and we often find this information misleading as well. The worst place to get camera recommendations is from a friend who has a similar engine to yours. Your friend often has no comparison, and that's the problem. The second worst place to get a camera recommendation is the technical department of the camera manufacturer. We have a lot of customers asking us to put a cam on their engine, we build them based on the recommendations of the cam company they spoke to. We usually think that recommendations are very inappropriate for a client's application.
Our experience with the characteristics of the cam in the vehicle is based on many years of feedback from our customers who have purchased engines from us. This is the real experience of the world. Our Superflo Dyno also showed us what exactly a given cam would do on a given size engine. The compression ratio is also a very important factor in determining how the cam will work in the engine. For the most part, our motor series are in pump gas compression range.
The dyno results below are from the various versions of the engine that have selected this cam.
Please read the test description in each of the dyno reports below carefully. This exact cam has been selected on many of our sbc street rod motors. These are all street engines with a gas pump with approx. 10.5:1 compression. Most 383 and 421 engines support our affordable NKB aluminum heads. Some other engine versions support AFR heads. Different intake and pitch ratios were used. The power numbers you get from our new range of Comp Cam custom cams far exceed most other cams on the market, with nearly identical pitch, duration and lobe offset. Speak louder.
You'll see this dyno results list grow over time as we continue to add other combinations. We also offer several other special wheels with fantastic profiles. We have a total of four different sbc Comp cameras listed with dyno results. We also offer all our cams in late model stepped or retro style flat for use in early non-roller blocks.

If you need an expert recommendation for your engine, please contact us via the "Seller Info" tab using the information below. We'll tell you which camera suits you best. Running a cam that is too large for a given combination is not only pointless in creating increased power, but causes increased loss of drivability and unnecessary wear on the valve train. You need enough cubic inches and/or compression ratio coupled with properly sized cylinder heads that provide enough flow to justify a specific size cam. Increasing the size of the cam always affects low-end and mid-range performance, but it would have an even greater impact if the cam selection was oversized to the point that top end power could not be achieved. Thus, choosing a camera that is too large becomes a double problem. Tuning also becomes more difficult with larger cams than necessary.
For a recommendation of the best camera for you, please contact us with the following information:
- Vehicle model or weight.
- Engine Size (cubic inches)
- About. Compression ratio.
- Cylinder head guide size.
- Single or double inlet tier (if double tier which model)
- Final gear ratio and overall tire diameter, if known.
- Gearbox model.
- Converter stall range.
- Your hp expectations and how you will use the vehicle (roadways, streets, striptease, show car, etc.)
- If Lopey idle is highly desirable. The size of the motor you have determines this with a given cam selection. We can tell you exactly how a given cam will sound in an engine.
- Make and type/series of lifts you drive. Very important!

Standard Small Block Chevy -uses “12” Prefix
It's important to note that the 1955-1957 versions require an oiling groove to be machined into the rear cam journal, but the camshafts are interchangeable.
Typically, a head with a high percentage can use a cam with more closely matched intake and exhaust lobe figures. Conversely, a head with a poor ratio between the intake and exhaust flow will benefit from more exhaust duration to evacuate the burned gases.How do I choose the right cam and head? ›
The secret to choosing a cam that will deliver the kind of performance you want is to figure out the rpm range where the engine should make the most power, and then choose a cam that will match the breathing characteristics of the cylinder heads, intake and exhaust manifolds, weight and gearing of the vehicle the ...Does camming increase HP? ›
Adjusting the camshafts so the cams are slightly ahead or behind will alter the engine's performance. Advancing the timing will cause the fuel intakes to open and close earlier, which improves low-end torque. Conversely, retarding the cam will improve high-end horsepower at the expense of low-end torque.Does a bigger cam need more timing? ›
The bigger the camshaft, the more it really needs part-throttle timing at low engine speeds.How much HP will a Stage 3 cam add? ›

What makes a cam better? ›
Rule of thumb: A cam with a wider lobe separation (112-116 degrees) allows torque to be spread over a larger portion of the engine's rpm range and offers better power throughout the upper-rpm range.Why is twin cam better? ›
Benefits of a Twin-Cam
The design of a DOHC allows for less restricted airflow at higher speeds. If the engine also has a multi-valve design, it also experiences improved combustion for better efficiency because of the placement of the spark plug.
The 327 L84 remained the most powerful Chevrolet small block production engine ever until the quad-cam LT5 came out in the 1990s. And it was the most powerful naturally-aspirated single-cam small block until the arrival of the LS6 engine in the early 2000s.What SBC makes the most horsepower? ›
The 350 had more torque and a production lifespan that endured for decades until the end of the Gen 1 SBC. Despite being down on inches to the 350, the 327 Chevy still lays claim to the most powerful production conventional small-block ever produced, the L84.Does bigger cam affect ignition timing? ›
How does cam timing affect ignition timing? In a short, two word answer... it doesn't. I get questions from people asking: "My cam is advanced 4 degrees, where should I set the ignition timing on my engine?" The complete answer is; Wherever your ignition timing is normally set at. Cam timing is VALVE timing.How much horsepower does a cam and heads add? ›
Cam and Heads Add Over 100 hp to Small-Block - Mini Mouse, Part 2.What's the difference between a Stage 1 cam and a Stage 2 cam? ›
Most Stage 1 type modifications are typically in the +10-15% power increase over stock. Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination. A typical Stage 2 has generally +20-25% more HP than stock.Do I need to degree my camshaft? ›
QUESTION. On a scale of 1 to 10, how important is it to do the [cam] degree step? Critical for achieving max cam performance, preventing piston-to-valve contact, and as a doublecheck against assembly errors, accurately locating TDC and degreeing in a custom cam should be a routine procedure for every hot rodder.What makes a cam aggressive? ›
In other words 'intensity' described how quickly the cam opened and closed from lower lift points to his standard lift point of 0.050”; the smaller the intensity, the more aggressive the opening and closing.What does more lift in a cam do? ›
A cam's "lift" number represents how far the valve will open inside the cylinder. More intake lift means that more air and fuel can enter the cylinder (except with direct injection, where the intake valve brings only air to the party) and, theoretically, more power can be made.
What is the advantage of over head cam? ›
It is shown that the principal advantage of overhead camshafts is the increased natural frequency of the valve train. The resulting improved dynamic characteristics of the valve-actuating mechanism make it possible to design camshaft profiles which expand the useful operating range of high-speed engines.How much HP does a cold air intake add? ›
Cold Air Intakes are said to improve your vehicle's performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn't enough power to put you back in your seat, it will give your car or truck a little pep in its step.How can I add 100 horsepower to my car? ›

Yes, especially if it has a nice lope to it. All my cammed cars got louder after adding a cam.Does the crank or cam turn faster? ›
Because one turn of the camshaft completes the valve operation for an entire cycle of the engine and the four-stroke-cycle engine makes two crankshaft revolutions to complete one cycle, the camshaft turns half as fast as the crankshaft.What are Stage 3 cam specs? ›
Specs: 231/244 .630"/.615" 112.5+2.5
The BTR Stage 3 N/A Camshaft (LS1/LS2/LS6) is the go to for people desiring an aggresive idle matched with a powerband that will stretch into the 450+ whp range around 6000 RPM when paired with quality supporting modifications.

Generally its because the aftermarket camshaft (s) are lobed to change the power band of the engine. Valves may stay open longer, close quicker than the stock cam was designed for. This is why idle may sound “choppier" and run rough at idle.How do I choose a cam for my engine? ›
Generally speaking, the longer the duration the higher the rpm range where the cam makes power. Short duration cams are good for low speed torque and throttle response while long duration cams are best or high revving engines that need to make lots of top end power.What is a Stage 2 cam? ›
Tuner Series Stage 2 Camshafts are designed to optimize horsepower and torque on engines featuring free-flowing intake and exhaust tracts, increased compression, and upgraded valvetrain. As a result, VTEC crossover is dramatic, allowing for that classic primary-to-secondary surge.Which engine is better DOHC or SOHC? ›
DOHC engines allow more intake and release of the air-fuel mixture than a SOHC arrangement. It enables the engine to be more powerful and gives you a better pickup. In simpler terms, a DOHC engine can produce more horsepower than a SOHC engine with the same displacement.Are twin cam engines reliable? ›
It is a really serious engine problem that needs a lot of attention to get fixed. The scariest part here is that it can fail at 15,000 miles and even the new hydraulic system can fail at 40,000 miles or less. The plastic shoes need replacing every 40,000 miles because of its weak durability.What is the purpose of a twin cam engine? ›
Twin cam refers to an car's engine which has two camshafts per cylinder bank. The two act together as one is responsible for intake valves while the other acts as for exhaust valves. This is more efficient than one cam for both jobs. The idea is to provide improved fuel efficiency and performance.How do you read a cam number? ›
Reading a Cam Card: Lobe Separation Angle (LSA)
On this cam card, you will see the LSA is 112 degrees. This figure is derived by adding the intake center line plus the exhaust center line and dividing by two. In this case: 108 + 116 = 224 degrees / 2 = 112 degrees.
You can identify a genuine Crane cam core by the distinctive copper plating between the lobes! Crane 8620 and 9310 steel billet cam cores are used by prominent racers, engine builders, and manufacturers.
What are the two types of cam? ›
Cams can be classified into two main types: oscillating cams, which are mounted on a rotating shaft and rotating cams, which are mounted on a stationary shaft.What does +2 mean on cam LSA? ›
The short answer is that the +2 refers to how the cam is ground relative to the LSA and the cam's intake centerline. The +2 in this instance means it has been machined with two degrees of advance built into the cam, placing the intake centerline at 110 degrees BTDC.How do I know if my cam is ground advanced? ›
To determine if a camshaft has ground-in advance, subtract the Intake Centerline from the Lobe Separation Angle. For example, a camshaft has an intake centerline of 107° and an LSA of 112°.Does camming a car make it faster? ›
Does Camming A Truck Make It Faster? In most cases, yes, but it depends on the model of the truck and which custom cam you use. With that said, aftermarket cams are designed for high-end performance, so you can typically expect to experience faster speeds after camming a truck.How do you identify a whooping crane? ›
The Four Keys to ID
Whooping Cranes are very large, tall birds with long necks and long legs. The bill is stout and straight; the overall slender body widens to a plump “bustle” at the tail. In flight the wings are broad and the neck is fully extended.
Simply measuring the diameter of the base circle, and subtracting that from the largest diameter of the cam, the lobe lift, will calculate the lift of the cam.What are crane look alikes? ›
Great Blue Heron (Ardea herodias) – Herons are found throughout the US. They are similar in characteristics and habits to egrets, the only exception being herons' blue-gray coloration. They can be distinguished from Sandhill Cranes by the “crooked” neck and curved (as opposed to cranes' flat) wings in flight.What are 3 advantages of cam? ›
- Greater speed in producing components.
- Greater accuracy and consistency, with each component or finished product exactly the same.
- Greater efficiency as computer controlled machines do not need to take breaks.
- High sophistication in terms of following complex patterns like tracks on circuit boards.
