Installing a Lunati camshaft is one of the most effective single upgrades you can make to unlock hidden horsepower and torque in a four-stroke engine. Known for aggressive lobe profiles and precision machining, Lunati cams have powered countless street machines, bracket racers, and weekend warriors to new performance levels. But success doesn’t come from just bolting in a cam—it requires careful planning, proper parts selection, and thorough troubleshooting. This guide covers everything from realistic installation costs and expected power gains to the most common pitfalls and how to fix them, giving you a complete roadmap for your cam swap.

The Lunati Difference: Why This Camshaft Brand?

Lunati has been a cornerstone of the performance camshaft industry since the 1960s. Their cams are manufactured in-house from high-quality billet steel or cast iron, then heat-treated and ground to exacting tolerances. Unlike generic replacement cams, Lunati offers purpose-specific profiles for street performance, strip racing, towing, and even marine applications. The company uses advanced lobe design technology to maximize area under the lift curve, which translates directly to more airflow and power without sacrificing idle quality or vacuum where needed.

For enthusiasts who want a cam that matches their driving style, Lunati provides extensive technical data including duration at 0.050″ lift, lobe separation angle, and recommended valve spring pressures. This level of detail allows you to pair the cam with the rest of your valvetrain for reliable operation. Many racers also appreciate Lunati’s Voodoo series, which features asymmetrical lobe profiles designed to accelerate the valve open faster and close more gently, reducing valvetrain stress while improving power.

If you are considering a Lunati cam, you are choosing a brand with decades of dyno-proven results and a strong support network of dealers and technical staff. That said, no cam performs well if installed poorly. Understanding the full cost and process upfront is crucial.

Full Cost Breakdown for Installing a Lunati Camshaft

The total investment for a Lunati camshaft installation ranges widely based on the specific cam model, whether you do the work yourself or hire a shop, and what additional components need to be replaced. Here is an expanded look at the numbers.

Camshaft Cost

Lunati camshafts are priced according to application and design. A basic flat-tappet cam for a small-block Chevy can start around $300, while a premium roller cam for a big-block Ford may cost $700 or more. The Voodoo hydraulic roller series typically sits between $400 and $600. Billet cams for custom applications can exceed $800. Always check your engine’s core and whether you need a cam with a fuel pump lobe or a specific thrust button setup.

Labor Costs (Professional Installation)

Professional labor for a cam swap typically runs $500 to $1,200, depending on the shop’s hourly rate and vehicle complexity. Some shops charge a flat fee; others bill by the hour (usually $100–$150 per hour). A straightforward cam swap in a small-block V8 might take 5–7 hours, but if the engine is in a tight engine bay (like many modern cars or trucks) or if the cam requires removal of the timing cover and front accessories, labor can jump to 10–12 hours. Expect additional charges if the shop needs to degree the cam, which is highly recommended.

Additional Parts and Consumables

A cam install rarely stops at just the cam. You should budget for these common extras:

  • Lifters: Flat tappet lifters (often sold in sets) $50–$150. Roller lifters can cost $200–$600.
  • Timing chain and gears: A high-quality double-roller set runs $60–$150. Avoid cheap single-row chains.
  • Valve springs: Recommended to match the cam profile. Budget $100–$250 for a set.
  • Pushrods: Possibly needed to check length; $50–$120 for a set.
  • Gaskets and seals: Timing cover gasket, oil pan gasket (if disturbed), valve cover gaskets, and front main seal. $30–$80 total.
  • Break-in oil and additive: Flat tappet cams require special break-in oil or ZDDP additive. $20–$40.

Total additional parts cost: $300–$1,200 depending on whether you replace springs and lifters with high-end units. Many builders recommend doing a full valvetrain refresh while the cam is out.

DIY vs. Shop Cost Comparison

Doing the work yourself saves the labor fee but requires tools: a cam degree kit ($50–$100), a torque wrench, dial indicator, and sometimes a harmonic balancer puller. If you already own basic tools, DIY cost is cam + parts ($600–$1,500). The shop route adds $500–$1,200, bringing total to $1,100–$2,700. For a high performance cam swap, spending the extra money on a professional degree job can prevent costly mistakes.

Power and Performance Gains: Realistic Expectations

How much horsepower and torque can you really expect from a Lunati camshaft? The answer depends heavily on the engine’s displacement, compression ratio, cylinder head flow, intake and exhaust system, and the specific cam profile chosen. However, typical gains from a mild street performance Lunati cam (like a Voodoo 268/276 hydraulic roller) on a 350 Chevy with good heads might be 25–35 peak horsepower and a similar bump in torque, with the torque curve shifting upward by 500–1,000 RPM.

Horsepower and Torque Numbers

  • Stock cam replacement: Expect 20–50 horsepower gain depending on how restrictive the factory profile was.
  • Mid-range torque: Aggressive street cams often improve torque from 2,500–4,500 RPM, making the car feel much stronger during acceleration.
  • Top-end power: Larger cams extend the power band to 6,000+ RPM, but may sacrifice idle quality and low-RPM vacuum.
  • Real-world example: A Lunati Voodoo 284/292 hydraulic flat tappet in a 383 stroker with aluminum heads and a dual plane intake produced 450 hp at 5,800 RPM and 470 ft-lb at 4,200 RPM on a chassis dyno, up from 380 hp with the stock cam.

It is important to note that a cam alone will not reach those numbers without supporting modifications. If your engine has restrictive heads, a poor intake, or inadequate exhaust, the cam’s potential will be capped. Plan to pair the cam with a good set of cylinder heads, a properly tuned carburetor or EFI system, and free-flowing exhaust.

Other Benefits Beyond Horsepower

  • Improved throttle response: Faster valve opening produces a crisp, immediate reaction to throttle input.
  • Better engine sound: A performance cam gives a distinctive lopey idle that many enthusiasts love.
  • Increased durability: Lunati’s hardened lobes and precise grinding reduce wear when properly broken in.

Keep in mind that a cam swap may reduce engine vacuum, affecting brake boosters and power brakes. You might need a vacuum canister or adjust your brake system. Also, automatic transmissions may require a lower stall converter to match the new power band.

Preparation and Parts Needed for Installation

Before you pull the engine apart, gather all components and tools. Rushing a cam swap leads to mistakes that can ruin the cam or engine.

Tools Required

  • Socket set, torque wrench, breaker bar
  • Harmonic balancer puller/installer
  • Camshaft degree kit (with degree wheel, dial indicator, and piston stop)
  • Feeler gauges, valve spring compressor
  • Engine stand (if removing engine) or engine support bar (for in-car swaps)
  • Gasket scraper, clean rags, assembly lube

Parts Checklist

  • Lunati camshaft (check specs against your engine)
  • Lifters (flat tappet or roller, matched to cam)
  • Timing chain and gears (double roller recommended)
  • Valve springs (if new cam requires higher lift)
  • Pushrods (verify length)
  • Gaskets: timing cover, oil pan, valve covers, intake manifold
  • Harmonic balancer (if old one is worn or incorrect)
  • Break-in oil (for flat tappet) or quality high-zinc oil
  • Thread locker, sealant

Also order a cam installation guide from Lunati or search for specific instructions for your engine family. Many common engines like small-block Chevy, Ford Windsor, or LS have well-documented procedures.

Step-by-Step Installation Overview

While a full step-by-step guide is beyond this article’s scope, here is a high-level sequence with critical notes. Always consult your service manual for specific torque specs and procedures.

  1. Disconnect battery, drain coolant, and remove accessories (radiator, fan, belts, alternator, power steering pump, etc.).
  2. Remove valve covers, rocker arms, pushrods, and lifters. Keep components in order for reinstallation or replacement.
  3. Remove timing chain cover, harmonic balancer, and timing set. Mark the position of the distributor if applicable.
  4. Carefully remove the old camshaft by gently sliding it out of the front bearing journals. Inspect the bearings for damage.
  5. Lubricate the new cam lobes heavily with approved assembly lube (Lunati recommends their own or a high-zinc grease). Lubricate the lifter bottoms and sides.
  6. Install the camshaft slowly to avoid nicking the bearings. Use a cam installation tool if needed.
  7. Install timing set with proper timing marks aligned. Set the cam gear to the correct phasing (usually straight up or advanced/retarded per cam card).
  8. Degree the camshaft using the degree wheel and dial indicator. Verify intake centerline matches cam card. Adjust offset keys or multi-index timing set as needed.
  9. Install lifters, pushrods, rocker arms. Adjust valve lash if adjustable. For hydraulic lifters, set preload per manufacturer spec.
  10. Reassemble timing cover, balancer, intake manifold, and all accessories. Fill with oil, prime the oil system (especially important for flat tappet cams).
  11. Start the engine and perform break-in per Lunati instructions. For flat tappet cams, run at 2,000–2,500 RPM for 20–30 minutes, varying RPM slightly. Do not let the engine idle.

Degreeing the cam is the most critical step. A mis-timed cam can cost 20–30 horsepower and risk valve-to-piston contact. If you are unsure, pay a professional.

Common Installation Mistakes and How to Avoid Them

Even experienced mechanics can make errors during a cam swap. Here are the most frequent problems and solutions.

1. Inadequate Break-In Procedure

Flat tappet cams require a specific break-in process to avoid wiping a lobe. Failure to use proper break-in oil, insufficient zinc content, or letting the engine idle too long can cause premature cam failure. Always follow Lunati’s break-in instructions exactly. Use a break-in oil with high ZDDP (zinc dialkyl dithiophosphate) or add a friction modifier.

2. Incorrect Valve Spring Pressure

If the new cam has higher lift than stock, the old valve springs may coil bind or not control the valve properly. Always check installed height and spring pressure. Use a spring tester or have a machine shop check. Replace springs with ones that match the cam’s lift and duration curve. Coil bind can destroy lifters and pushrods.

3. Timing Set Misalignment

Installing the timing chain incorrectly by one tooth or using the wrong keyway can put the cam out of phase. Always double-check timing marks and degree the cam. A common error is assuming “straight up” from the marks is correct—many racing cams require advance or retard. The cam card is your bible.

4. Ignoring Lifter Bore Condition

Worn lifter bores or excessive clearance can cause oil pressure loss and lifter noise. If the engine is high mileage, consider a lifter bore reaming or bushing installation. New lifters in a worn bore can fail quickly.

5. Improper Lash Adjustment

For mechanical (solid) lifter cams, setting the lash too tight can burn valves; too loose kills power and makes noise. For hydraulic lifters, too much preload can cause the valve to hang open at high RPM. Use the cam card specs and a feeler gauge or dial indicator method.

6. Overlooking Oil Pump Priming

After installation, the oil pump may lose prime. Crank the engine with the distributor removed and use a priming rod to spin the oil pump before starting. This ensures oil reaches the lifters and bearings immediately.

Tuning After Your Cam Swap

A cam change alters the engine’s volumetric efficiency, which affects air-fuel ratio, idle speed, and timing requirements. You will need to re-tune the engine.

Carbureted Engines

You may need to change the carburetor jets, power valve, and possibly accelerator pump cam. A larger cam often increases the need for fuel at high RPM while reducing vacuum signal, which can cause poor part-throttle response. Start with a richer jetting and adjust based on wideband O2 readings.

EFI Systems

Modern EFI systems will require a retune. The idle air control (IAC) counts will change due to lower vacuum. Adjust your idle speed and fuel maps. If your ECU has a “canned” tune for performance cams, use that as a baseline. Otherwise, visit a professional tuner.

Timing and Spark Advance

A cam with more overlap often benefits from more initial timing and a faster mechanical advance curve. Experiment with total timing (typically 34–38 degrees BTDC at high RPM). Use a dial-back timing light. Detonation must be avoided.

Transmission and Torque Converter

If the cam shifts the power band higher, an automatic transmission may need a higher stall speed torque converter (2,400–3,200 RPM is common). A manual transmission may need a heavier flywheel for streetability. Adjust shift points if using a standalone transmission controller.

Conclusion

Installing a Lunati camshaft is a proven path to significant performance gains, but it demands attention to detail, proper budgeting, and methodical execution. The total cost of $900 to $2,700 buys you not just a cam, but a transformation in how your engine delivers power. Real horsepower gains of 20 to 50 ponies are achievable, along with a more aggressive sound and throttle response that makes every drive an event. By carefully selecting the right cam, replacing companion parts, and breaking in the cam correctly, you can avoid the common headaches that plague many first-time installers. Whether you tackle the job yourself or hire a professional, the key is preparation and following the cam card specifications.
