The 500 Horsepower 1967 Camaro: A Complete Build Guide
There’s nothing quite like the sight of a first-generation Chevrolet Camaro rumbling down the road. For enthusiasts, the 1967 model year holds special significance: it was the year the Camaro was born, and it remains a timeless canvas for performance builds. While restoring a ’67 to factory spec is a worthy pursuit, many owners want to unlock the car’s true potential. A 500-horsepower target sits in a sweet spot—it’s aggressive enough to dominate at the track or on the street, yet it doesn’t require the exhaustive engineering or six-figure budget of a 1,000-hp monster. Reaching this number requires disciplined part selection, realistic budgeting, and a clear understanding of how each component contributes to the final output. This guide covers the critical parts, the costs you can expect, and the real-world results of a properly executed 500-hp build for a 1967 Chevy Camaro.
Defining the Power Target: What 500 Horsepower Means for a First-Gen Camaro
Before opening a parts catalog, it is worth understanding what 500 horsepower actually represents in the context of a 1967 Camaro. The factory-rated high-performance engines for this model year (such as the 396 big-block in the SS396) produced roughly 325 to 375 gross horsepower. A 500-hp output therefore represents a jump of roughly 100 to 175 horsepower over period-correct factory muscle. That difference is transformative: it turns a brisk cruiser into a genuinely fast machine capable of low-12-second or even high-11-second quarter-mile passes with proper traction.
It is also important to note that 500 hp at the flywheel (crankshaft) is different from 500 hp at the rear wheels. Drivetrain losses through the transmission, driveshaft, and differential typically consume 15 to 20 percent of the engine’s output. A car that makes 500 hp at the crank will likely put 400 to 425 hp to the pavement. If your goal is 500 rear-wheel horsepower, you will need to target approximately 600 flywheel horsepower. For the purposes of this article, we will focus on achieving 500 hp at the flywheel, which is the most common benchmark used in parts catalogs and engine builder discussions.
Choosing the Right Foundation: Small-Block vs. Big-Block
The 1967 Camaro originally offered small-block (230, 250, and 327 cubic inches) and big-block (396 cubic inches) options. Both engine families can achieve 500 hp, but the path differs significantly.
Small-Block Builds
A small-block Chevrolet (SBC) is lighter, less expensive to build, and benefits from a massive aftermarket parts ecosystem. Reaching 500 hp with a small-block requires more aggressive camshaft timing, higher compression, and elevated rpm compared to a big-block. A stroker small-block displacing 383 or 406 cubic inches is a common recipe: it provides the displacement needed to support high power without excessive strain. Expect a peakier powerband and a need for premium fuel, but the engine will weigh roughly 100 pounds less than a big-block, which helps front-end handling.
Big-Block Builds
The big-block Chevrolet (BBC) makes 500 hp with less effort and lower rpm. More displacement (454, 468, or 496 cubic inches) produces abundant torque, making the car feel effortless on the street. The downsides include higher initial engine cost, added weight over the front axle, and more limited chassis clearance for certain intake and exhaust configurations. For a 1967 Camaro, a big-block swap is mechanically straightforward, but you will need heavy-duty springs and possibly an aftermarket subframe to manage the extra weight.
Both paths are valid. The small-block route is popular for budget-conscious builds and those who prioritize cornering. The big-block route suits owners who want maximum torque and a relaxed high-power driving experience.
Core Engine Components for a 500-Horsepower Small-Block
Since the small-block is the most common choice for first-gen Camaro builds, this section details a stroker recipe that reliably produces 500 hp. The budget builds described below use a combination of production-based parts and high-performance aftermarket pieces.
Engine Block and Rotating Assembly
A production 350ci block that has been sonic-tested and bored to 4.030 or 4.040 inches provides the foundation. For a 383 stroker, install a forged steel crankshaft with a 3.75-inch stroke, forged connecting rods (5.7 or 6.0 inches depending on piston choice), and forged aluminum pistons with a compression ratio of 9.8:1 to 10.5:1. This combination displaces 383 cubic inches and supports 500 hp with proper breathing. Expect to pay $2,000 to $3,500 for a quality rotating assembly from manufacturers such as Eagle or Scat.
Camshaft Selection
A hydraulic roller camshaft with approximately 230 to 240 degrees of duration at 0.050-inch lift and 0.520 to 0.560 inches of valve lift is appropriate for a 500-hp street small-block. A lobe separation angle of 112 degrees provides a good compromise between idle character and top-end power. The cam should be paired with matching springs (good for at least 0.600 inches of lift) and hardened pushrods from brands like Comp Cams or Lunati. Budget $400 to $800 for the cam, lifters, springs, and timing set.
Cylinder Heads
Cylinder heads are arguably the most important component for reaching 500 hp. Factory iron heads will not get the job done. Aftermarket aluminum heads from AFR, Brodix, or Dart with 190 to 210 cc intake runners and 2.02/1.60-inch valves flow the air needed for the power target. Expect 290 to 310 cfm of intake flow, which is sufficient for 500 hp on a 383. Aluminum heads also reduce weight and allow higher compression without detonation thanks to superior heat dissipation. A set of assembled aftermarket aluminum heads costs $1,200 to $2,000.
Intake Manifold and Induction
A dual-plane intake manifold (such as the Edelbrock Performer RPM Air-Gap) offers excellent mid-range torque and is well-suited for a street-driven Camaro. For a single-carbureted setup, a 750 cfm carburetor (Holley or Quick Fuel) provides the right air-fuel mixture. If you prefer fuel injection, a Holley Sniper or FiTech self-tuning EFI system simplifies cold starts and driveability while supporting the power goal. EFI costs more upfront ($800 to $1,500) but eliminates many of the tuning headaches associated with carburetors.
Exhaust System
A full exhaust system with long-tube headers (1.75-inch primary tubes, 3-inch collectors), free-flowing catalytic converters (if required for your region), and 3-inch mandrel-bent pipes with chambered mufflers is mandatory. The headers should be coated or ceramic-coated to manage underhood temperatures. Expect to spend $400 to $1,200 on headers and $600 to $1,200 on the rest of the exhaust system.
Supporting Systems: Cooling, Fuel, and Ignition
A 500-hp small-block generates significant heat and requires a robust fuel delivery system. The following upgrades are non-negotiable:
- Cooling: A three-row aluminum radiator (Be Cool or DeWitts) paired with a high-flow mechanical fan or dual electric fans keeps engine temps stable in traffic. Budget: $400 to $700.
- Fuel System: For a carbureted engine, a high-volume mechanical fuel pump (Holley Blue or similar) with a return-style regulator and 3/8-inch fuel line is sufficient. For EFI, you need an in-tank electric pump, a 40-amp relay kit, and a fuel pressure regulator. Budget: $200 to $600.
- Ignition: A distributor with a locked-out mechanical advance (for crank-trigger systems) or a performance HEI distributor like those from MSD or Davis Unified Ignition provides strong spark. Pair it with a CDI box (MSD 6AL or equivalent) and high-performance spark plug wires. Budget: $300 to $600.
Cost Breakdown: What You Will Spend for 500 Horsepower
The cost to build a 500-hp 1967 Camaro depends heavily on whether you do the work yourself, the condition of the starting vehicle, and your choice of parts. The following table estimates a realistic budget for a small-block stroker build with owner-performed assembly work. Professional labor will add $2,000 to $5,000 depending on the shop.
- Core engine block (machined and cleaned): $400 – $800
- Forged rotating assembly (crank, rods, pistons, rings, bearings): $2,200 – $3,500
- Aftermarket aluminum cylinder heads (assembled): $1,400 – $2,000
- Hydraulic roller camshaft kit (cam, lifters, springs, timing set): $500 – $800
- Intake manifold (dual-plane): $250 – $400
- Carburetor (750 cfm): $400 – $700
- Long-tube headers: $400 – $900
- Exhaust system (mufflers, pipes, clamps): $600 – $1,200
- Aluminum radiator and electric fans: $500 – $900
- High-volume fuel pump and lines: $200 – $400
- Performance ignition system: $400 – $700
- Gaskets, fluids, oil pan, timing cover, hardware: $300 – $500
- Dyno tuning session: $500 – $1,000
- TOTAL (estimated, owner labor): $8,000 – $13,800
If you buy a crate engine that is already rated at 500 hp (such as the Chevrolet Performance 383 or ZZ502), you will pay $7,000 to $10,000 for the engine alone and still need to source the carburetor, headers, and supporting systems. The crate engine route eliminates the risk of a flawed assembly but reduces the ability to tailor the build to your specific driving style.
Drivetrain Upgrades to Handle 500 Horsepower
A 500-hp engine will quickly destroy a stock 1967 Camaro transmission and rear axle. You must plan for drivetrain upgrades as part of the overall build cost.
Transmission Options
The factory two-speed Powerglide or three-speed Saginaw transmissions are not up to the task. The most common options include:
- TH350: A three-speed automatic that is compact and affordable. A well-built TH350 can handle 500 hp, but you should install a shift kit and a high-capacity cooler. Budget for a rebuild with performance parts: $800 to $1,500.
- 4L60E (700R4 variant): A four-speed automatic with overdrive, which reduces highway rpm and improves fuel economy. Requires an electronic controller and a robust build to survive 500 hp. Budget: $1,500 to $2,500.
- Tremec TKO 600: A five-speed manual transmission that is popular for classic muscle cars. It features a 0.82 overdrive ratio and is rated for 600 lb-ft of torque. Budget: $2,200 to $3,000 for the transmission and installation kit.
Rear Axle
The original 10-bolt rear axle is the weak link in a high-power Camaro. It will break under hard launches. Upgrade to a 12-bolt or a Ford 9-inch rear end. Both options are available as direct-fit assemblies from Moser Engineering, Strange Engineering, or Currie Enterprises. Budget: $2,000 to $3,500 for a complete assembly with axles, differential, and brakes.
Suspension, Brakes, and Tires: Making the Power Usable
500 horsepower is only as good as the car’s ability to put that power to the ground and stop effectively. The 1967 Camaro uses a front subframe and rear leaf spring suspension that benefits from targeted upgrades.
Front Suspension
Replace the factory control arm bushings with polyurethane units, install 1.25-inch or 1.5-inch diameter anti-sway bars, and upgrade the front springs to a rate that compensates for the lighter aluminum heads (if applicable). Many owners install a quick-ratio steering box to improve turn-in response. Budget: $600 to $1,200 for a complete front suspension kit from Hotchkis or Global West.
Rear Suspension
Ladder bars or a four-link system (such as the RideTech or QA1 systems) provide the traction needed for hard launches without wheel hop. An anti-roll bar keeps the car flat in corners. For street-driven cars, a set of Cal-Tracs traction bars combined with adjustable rear shocks (Viking or QA1) offers a good compromise. Budget: $500 to $1,500.
Brakes
Disc brakes are essential. The stock front drum brakes are insufficient. Install a front disc brake conversion kit (Wilwood or Baer) with 12-inch rotors and four-piston calipers. For the rear, a disc conversion is recommended but not strictly required if you have a good proportioning valve and high-quality drum components. Budget: $800 to $1,800 for a front kit; $400 to $800 for a rear conversion.
Tires
A 500-hp Camaro needs a wide tire to transmit power. A 275/40R17 or 295/35R18 rear tire on a 17- or 18-inch wheel provides a substantial contact patch. Mickey Thompson or Nitto drag radials are good choices for street-and-strip use. Budget: $1,200 to $2,000 for a set of four wheels and tires.
Dyno Results and Real-World Performance
A properly built 383 stroker with the specifications above should produce 500 to 520 hp at 5,800 rpm and 480 to 510 lb-ft of torque at 4,200 rpm on a chassis dynamometer. Adjusted for drivetrain loss, this translates to approximately 410 to 430 rear-wheel horsepower.
In a 1967 Camaro weighing approximately 3,200 pounds, this power level yields the following real-world performance:
- Quarter-mile: 11.8 to 12.3 seconds at 114 to 118 mph with good traction and a manual transmission.
- 0-60 mph: 3.9 to 4.3 seconds.
- Street manners: The engine idles with a noticeable lope but remains tolerable for daily driving with a hydraulic roller cam and a 2,500-rpm stall converter (automatic) or a light clutch pedal (manual).
- Fuel economy: 12 to 15 mpg on the highway with EFI and overdrive; 8 to 11 mpg with a carburetor and a TH350 without overdrive.
Common Pitfalls and How to Avoid Them
Many builders overspend on exotic components and then neglect the supporting systems that make the engine reliable. The most common mistakes include:
- Underestimating cooling needs: A high-performance engine generates significant heat, especially in stop-and-go traffic. Do not reuse the stock radiator; it will not keep the engine cool.
- Ignoring drivetrain capacity: Building a 500-hp engine only to install it behind a stock TH350 or 10-bolt axle is a recipe for immediate failure. Upgrading the transmission and rear axle adds cost, but it is cheaper than rebuilding them after they break.
- Skipping dyno tuning: An engine that is assembled from quality parts can still run poorly if the air-fuel ratio, timing curve, and idle speed are not optimized. Professional dyno tuning costs $500 to $1,000 and is the best money you can spend to ensure the engine performs as intended.
- Choosing the wrong camshaft: An overly aggressive camshaft can kill low-end torque and make the car unpleasant on the street. Stick to the duration and lift ranges recommended for a 500-hp street small-block and avoid the temptation to go “one size bigger.”

Final Thoughts
Building a 1967 Chevy Camaro to produce 500 horsepower is an achievable goal that requires a methodical approach to part selection, budget planning, and systems integration. The key takeaway is that every component matters: from the reciprocating assembly to the smallest gasket, each part plays a role in delivering reliable power. The total investment will likely land between $8,000 and $20,000 depending on the build path you choose, the condition of the starting car, and whether you perform the labor yourself or pay a shop. The payoff is a classic muscle car that accelerates with authority, handles with confidence, and stands out at any car gathering. Whether you choose a small-block stroker or a big-block torque monster, the process of building and dialing in a 500-hp Camaro is an education in automotive engineering and a deeply rewarding experience.
