10 Best Camshaft For 350 Chevy 2025 in the United States

The COMP Cams K12-600-4 Thumpr camshaft is designed for those looking to improve performance in Chevrolet Small Block engines, particularly popular in muscle cars and street rods. This camshaft boasts impressive specifications, including a lift of 0.479"/0.465", 227/241 duration at .050", and a 107-degree lobe separation angle. It operates optimally within a 2,000 to 5,800 RPM range, making it a solid choice for spirited street driving and racing scenarios.

One of its main strengths is the distinctive choppy idle it produces, which many enthusiasts find appealing. This camshaft is especially effective when paired with aftermarket converters and rear gears, enhancing the engine’s power band and creating a powerful, throaty exhaust note that muscle car fans crave. Users appreciate the inclusion of a comprehensive K Kit, which typically contains not just the camshaft, but also lifters, valve springs, retainer kits, and timing set, facilitating a complete upgrade.

There are some drawbacks to consider. This camshaft is best suited for performance applications and may not be ideal for daily drivers or those who prefer a smoother idle. Additionally, it does not fit newer LT1/LT4 engines or factory roller Small Blocks built from 1985 onward, which can limit its applicability.

The Edelbrock 2102 Performer-Plus Camshaft and Lifter Kit is designed for 350 Chevy engines, offering a balance of performance and drivability. This camshaft features a cast construction with hydraulic lifters, making it durable and relatively easy to install. The camshaft has an intake duration of 204 degrees and exhaust duration of 214 degrees at 0.050-inch lift, offering a good balance between low-end torque and mid-range power. The valve lift is 0.420 inches for intake and 0.442 inches for exhaust, which can improve airflow and performance without over-stressing the engine components.

The 112-degree lobe separation angle (LSA) helps in achieving smooth idle and good vacuum, making it suitable for street performance applications. The RPM range is adequate for daily driving and occasional spirited driving. However, if you are looking for a high RPM race-focused camshaft, this might not be the best choice. Despite being introduced back in 2005, it remains a relevant option for those looking to upgrade their 350 Chevy engine. The kit also includes lifters, providing a complete solution for camshaft replacement or upgrade.

On the downside, the product’s weight appears to be incorrectly listed as 0.01 ounces, which is likely a typographical error. Also, for individuals aiming for top-tier racing performance, they might need to look for a more aggressive camshaft with higher lift and a different LSA. This camshaft kit is ideal for those who want to enhance their vehicle's performance for everyday driving and mild performance enhancements.

The Edelbrock 2172 Performer-Plus Camshaft and Lifter Kit is designed for 350 Chevy engines and includes a camshaft, hydraulic lifters, assembly lube, and full instructions, making it a comprehensive package for engine enthusiasts. One of its notable strengths is the valve lift, with an intake valve lift of 0.484 inches and an exhaust valve lift of 0.510 inches, which suggests a significant improvement in engine breathing. The intake cam lift is 0.280 inches and the exhaust cam lift is 0.295 inches, indicating a moderate enhancement suitable for stock engines.

However, it's important to note that this kit is not compatible with dual springs and should only be used with stock ratio rocker arms, limiting its flexibility for more aggressive engine builds. The kit's comprehensive nature and decent performance upgrades make it ideal for users looking to boost their 350 Chevy engine's performance without venturing into high-performance or racing setups. The restriction on using dual springs and the need to stick to stock ratio rocker arms may limit its appeal for those seeking more customized or high-performance applications.
