If you own a Ram truck and want to boost its power and performance, installing a performance camshaft is one of the most effective upgrades you can make. The camshaft controls the timing and duration of your engine's valve openings, directly influencing airflow and combustion efficiency. For Ram owners in Nashville—whether you’re hauling gear to a jobsite, towing a boat to Old Hickory Lake, or hitting the trails at Windrock—a performance camshaft can deliver noticeable horsepower and torque gains. This guide provides a detailed, step-by-step walkthrough for installing a performance camshaft in your Ram, with practical advice for achieving Nashville-level power gains.
Understanding the Benefits of a Performance Camshaft
A performance camshaft improves your engine's volumetric efficiency, allowing more air and fuel into the cylinders and expelling exhaust gases more effectively. The result is increased horsepower across the rev range, improved throttle response, and often a more aggressive exhaust note. For Ram trucks, which are already torquey workhorses, a well-chosen camshaft can shift the power band to better suit towing or off-road needs—delivering that extra grunt when you need it most. Beyond the seat-of-the-pants feel, a performance cam also optimizes engine efficiency, reducing the tendency to downshift on grades and improving overall driveability when combined with proper tuning.
Choosing the Right Performance Cam for Your Ram
Not all camshafts are created equal, and selecting the wrong one can hurt performance or cause drivability issues. The key specs to consider are intake/exhaust duration, lobe separation angle (LSA), and valve lift. For a Ram 1500 with the 5.7L Hemi, popular choices include cams with around 220-230 degrees of duration at 0.050 inch lift and a LSA of 110-112 degrees. These offer a nice balance of low-end torque for towing and mid-range power for passing. For the 6.4L Hemi in Ram 2500/3500 trucks, slightly more aggressive profiles are common. Diesel Ram owners with the 6.7L Cummins can also benefit from performance camshafts that improve spool-up and top-end power, though installation is more involved due to the overhead cam design on later models. Always consult with a reputable cam manufacturer like Comp Cams or Crower and discuss your specific goals—towing, daily driving, or weekend racing—before buying.
Tools and Parts Required
Having the right tools and parts on hand before you start will save time and prevent frustration. Here is a comprehensive list:
- Performance camshaft kit (includes cam, lifters, springs, retainers, locks, and timing chain if applicable)
- Socket set (metric and SAE), wrenches, and torque wrench
- Camshaft installation tool or long bolt for aligning timing marks
- Timing chain/gear puller and damper puller
- Gasket scraper, razor blade, and sealant (RTV or anaerobic)
- New gaskets for timing cover, oil pan (if needed), and valve covers
- Engine oil (break-in oil recommended), coolant, and assembly lube
- Service manual for your Ram model (downloadable from Ram Trucks or aftermarket sources)
- Piston stop or degree wheel for verifying cam timing
- Safety equipment: gloves, safety glasses, jack stands
If you’re planning to upgrade valve springs or replace the timing chain as part of the project, gather those components now. Many cam kits include lifters and springs matched to the cam profile, but double-check compatibility with your engine year.
Step-by-Step Installation Process
1. Vehicle Preparation
Start with a cool engine. Disconnect the negative battery terminal and remove both battery cables if your Ram has dual batteries (common on diesel models). Drain the engine oil and coolant into appropriate containers. Remove the fan shroud, radiator hoses, and if necessary, the radiator to create working clearance. On Hemi Rams, you’ll need to remove the intake manifold, throttle body, and fuel rails. For Cummins engines, the intake and exhaust manifolds must come off. Clean the work area thoroughly to avoid debris falling into the engine.
2. Remove the Front Timing Cover and Timing Chain
Follow your service manual to remove the serpentine belt, crank pulley, harmonic damper, and water pump. For Hemi engines, the timing cover is integral to the oil pump, so take care when separating it from the block. Mark the timing chain relationship between the crank and cam sprockets with a paint marker before removal—this ensures proper timing during reassembly. Remove the camshaft retaining bolts (on pushrod engines) or the camshaft locking plate (on some Hemi variants). Carefully slide out the old camshaft, noting its orientation (if applicable, some engines have a thrust washer). On overhead-cam Cummins engines, the camshafts are accessed by removing the rocker arms and then sliding the cam forward out of the block; this is more complex and may require special tools.
3. Install the New Camshaft
Apply a generous coat of assembly lube to the camshaft lobes and journals. Gently insert the new camshaft into the engine block, taking care not to damage the cam bearings. Rotate the cam as you slide it in to seat the lobes into the lifters. For pushrod engines, ensure lifters are properly placed (some swap in new lifters at this point). Reinstall the timing chain, aligning the timing marks exactly as the factory designed. For a degree wheel check, use a piston stop to find TDC and verify that the cam timing is within specifications. This step is crucial for maximizing power gains—do not skip it.
4. Reassemble and Tear Down
Install new gaskets and reattach the timing cover, water pump, and all accessories. Replace the harmonic damper and crank pulley with a new bolt (many manufacturers recommend replacing it). Refill engine oil with a break-in oil (high zinc content) and coolant. Reconnect the battery. Before starting, prime the oil system by cranking with the fuel pump relay or injectors disabled until oil pressure builds (watch the gauge or use a mechanical gauge). Then start the engine and allow it to idle at around 2000 RPM for 20 minutes to break in the cam and lifters. Listen for any ticking—a sign of lifter issues. Check for leaks and verify that the timing is stable.
5. Post-Installation Checks and Tuning
After the break-in, change the oil and filter to remove any debris. If you installed a cam that changes the engine’s airflow characteristics significantly, a custom tune is highly recommended. The stock ECU may not adjust fuel and timing properly, leading to poor performance or engine damage. Many Ram owners use handheld tuners from HP Tuners or professional dyno tuning at a shop like Hennessey Performance (based in Texas but serves nationwide).
Performance Tuning for Maximum Gains
Installing the camshaft is only half the equation. To realize the full potential, you must tune the engine management system. A performance cam shifts the power band, often requiring adjustments to idle speed, fuel injection timing, and ignition advance. For Ram trucks with the 5.7L or 6.4L Hemi, aftermarket tuners like DiabloSport or HP Tuners allow you to modify these parameters. Custom tunes tailored to your specific cam profile can yield 30-50 additional horsepower beyond the cam swap alone. For diesel Rams, tuning is equally important—ECM upgrades from companies like PPEI (Pioneer Performance Engineering and Innovation) can optimize fuel delivery and boost pressure to match the new cam. Always work with a reputable tuner who has experience with your exact engine and camshaft.
Real-World Power Gains: What to Expect
On a 5.7L Hemi Ram 1500, a mild performance cam (e.g., 220/228 duration, 0.575/0.575 lift, 112 LSA) can produce around 30-40 horsepower at the wheels and 25-35 lb-ft of torque, with peaks shifted higher in the RPM range. A more aggressive cam (230/236 duration, 0.610 lift) may yield 50-70 hp but often requires supporting mods like upgraded valve springs, headers, and a better intake. On a 6.4L Hemi, gains are similar proportionally. For 6.7L Cummins trucks, performance cams can add 50-100 hp when combined with a tuner and exhaust upgrades. These figures assume proper tuning; without tuning, gains are often minimal or negative. Always budget for a dyno session or professional tune.
Common Mistakes and How to Avoid Them
- Skipping the degree check: Even with pre-marked timing sets, manufacturing tolerances can cause misalignment. Always verify cam timing with a degree wheel.
- Reusing old lifters: On pushrod engines, lifters wear to the factory cam lobes. Installing a new cam with old lifters can cause rapid cam wear. Always replace lifters.
- Inadequate break-in procedure: The first 20 minutes of running are critical. Use proper break-in oil and vary RPM between 2000-2500, avoiding prolonged idle.
- Neglecting valve train upgrades: More aggressive cams require stronger valve springs to prevent valve float at high RPM.
- Ignoring fuel system limitations: On Hemi engines, the stock fuel injectors may be maxed out with a large cam; consider upgrading to 42lb or 55lb injectors.
Maintaining Your Performance Camshaft
Once installed, longevity depends on proper maintenance. Use high-quality motor oil with sufficient zinc (ZDDP) for flat-tappet cams or roller cams as recommended by the manufacturer. Change oil every 3,000-5,000 miles and use the correct viscosity (5W-20 or 5W-30 for Hemi, depending on year). Avoid long periods of idling, which starves the cam of oil. Regularly inspect valve lash (if adjustable) and listen for any unusual noises. With care, a performance cam should last as long as the engine.
Final Thoughts for Nashville Ram Owners
Installing a performance camshaft in your Ram is a rewarding project that can transform its capabilities, whether you're launching a boat at Percy Priest Lake, hauling gear to a Music Row studio, or just enjoying the drive on I-440. Take your time, follow the service manual, and don't cut corners on assembly lube, timing verification, and break-in. Pair the cam with a proper tune, and you'll have a truck that delivers Nashville-level power and a soundtrack to match. If you’re not confident in doing the installation yourself, many performance shops in the area, such as Velocity Restorations in Pensacola (a popular road trip from Nashville), can handle the job. For parts and advice, local speed shops like Frazier Motorsports in Nashville are excellent resources. Happy wrenching!
