Hughes Cam
Choosing a camshaft is probably the most important part of designing an engine combination, yet it can be the most confusing and frustrating part of your engine building experience. One of the problems is the confusing and contradictory way that cams are advertised and the way the specifications are listed. We ask lots of questions to get you the best cam for your application - help us help you with good answers.

There are some basic principles that are universal , apply to all brands of camshafts and must be understood.

Cam Categories: (See below for more detailed information)

1. Towing & mileage
2. Light towing, cruiser, street, stock replacement
3. Whiplash
4. Hot Resto Cruiser
5. Hot Street / 10% Strip
6. Street / Strip 50/50

The cylinder pressure is a result of 5 things, the static compression ratio, cylinder head material (iron or aluminum), the closing point of the intake lobe, the altitude of operation of the engine and the final displacement of the engine. When using 93 octane gasoline, build your engine for 165psi cylinder pressure with iron heads. Whenusing aluminum heads aim for 195 psi cylinder pressure.This is generally the maximum safe pressure and power without detonation or odd spark curves. As the camshaft gets larger (duration at .050" tappet lift), the static compression ratio must be raised to maintain the cylinder pressure. For maximum power in your engine, request our computer generated cylinder pressures/static compression ratio numbers when ordering your Real Chrysler Camshaft.
When replacing a Mopar Performance camshaft with a Hughes Engines "real" Chrysler camshaft, use one that is 5º to 7º smaller at .050" tappet lift for increased power in all RPM ranges.

  * Camshaft Frequently Asked Questions

   13. A mechanical cam will produce more power than a hydraulic cam of the same specs. However, we have some "stiff" hydraulic lifters that are the next best thing to a mechanical lifter.

      We don't just want to sell you a cam. We want to sell you a cam that works for you. That is why we ask all of these pain in the butt questions! Do not use the answer "stock", as many "stock" ooptions were available. The better your answers, the better we can serve you. Answers like: But i could use a supercharger later on, etc. do not help! What do you need a cam for now?!
The graph below describes what you should expect when you build an engine for a specific power range. If the engine breathing combination (cam, carb, intake, heads, headers and compression ratio) are properly matched, the duration at .050" on the intake lobe will generally dictate where the power curve will occur. This way you can compare the potential results with cams from various sources. Note that as the engine power increases, the power curve will become narrower and steeper. It will also move up in the RPM scale.

If your combination develops power in the "A" curve and you choose a smaller (duration @ .050") camshaft, you can expect to see your power curve move to the left, the "B" curve. Notice that the "B" curve is wider, but has a lower peak power. If you choose a larger (duration @ .050") camshaft, your power curve will move to the right, the "C" curve. This curve is narrower, but has higher peak power. If you pick a camshaft with the same or very close (2° to 3° duration @ .050") your power curve will be approximately the same. HOWEVER, when installing a HUGHES ENGINES "real" CHRYSLER CAMSHAFT you can expect to see the maximum power increase and the power curve widen. With a Hughes Engines camshaft (curve "D"), the power will start sooner and pull longer, resulting in more peak power. The RPM location of the peak power will remain about the same as long as the duration at .050" on the intake lobe remains the same (curve "D" vs. curve "E")

Advancing and Retarding the Camshaft
Advancing the camshaft, (a lower intake lobe center line number, 104 vs.108 for example) will tend to start the power band sooner in the RPM range. It will also increase the cylinder pressure. Retarding the camshaft (a higher intake lobe centerline number 108 vs. 104) will generally start the power band later in the RPM range and decrease the cylinder pressure. However, these rules are not absolute. Depending on the engine combination, the opposite results can occur. Call for details with your specific combination.
A WARNING on Computer Engine Designing and Testing
We have many people call us requesting timing figures to enter in their computer dyno programs. We are happy to supply these figures. However, we will only supply them at .050" tappet lift because we do not consider the advertised duration figures to be relevant. Advertised duration is not checked at the same point with every manufacturer. A lot of lower priced computer dyno programs will not accept duration at .050" tappet lift figures. Most of these simulation programs are not designed with Mopar engine features, such as quench heights, longer rods, lifter diameter, etc. Therefore, the results from these types of programs are misleading. The better programs (and there are very good ones) naturally cost considerably more. If the program you are using doesnt ask much (such as flow figures, quench heights, rod lengths, cam timing at .050", etc.), do not expect good indications of the power potential..

These cams have a very aggressive idle and explosive power right off idle. This cam will pull hard to 5000/5500 rpm. Vacuum will be low (9" - 11")
Recurved distributor, HP ignition, dual exhaust or headers, 4bbl low rise type manifold. 7-8.5:1 compression with iron heads in small blocks, 7.5 to 8.5:1 in big blocks. Small blocks with aluminum heads can be as high as 9.25:1 and big blocks 10.25:1.
Strokers increase the displacement of an engine which in turn makes the cam act smaller.
Generally if you pick a cam 2 sizes larger than the characteristics you are looking for, it will be a good choice. If you are confused, please call us.
Our 6 pack replacement cams have the same overlap as the OEM 6 pack, same duration @ .050" on the intake with a reduced exhaust duration. We have more area under the curve for better breathing.
