Product Details

The COMP Cams 20-670-20 Nostalgia Plus Hydraulic Flat Tappet Camshaft is engineered for Chrysler 273-360 small block engines seeking a classic muscle car power profile with modern camshaft technology. Part of COMP Cams' renowned Nostalgia Plus series, this hydraulic flat cam delivers a aggressive street/strip grind with 233 degrees of intake duration and 240 degrees of exhaust duration at 0.050" lift — ideal for builders chasing that classic big-block sound and power feel from a small block platform.

The Nostalgia Plus series is nitride-hardened ("Nit") for increased surface durability, improved wear resistance, and extended camshaft life — especially important when used with flat tappet lifters in high-performance applications. The nitriding process hardens the lobe surface without compromising the core material integrity, making this an excellent choice for both street-driven restorations and dedicated track builds.

Key Features:

  • Intake Duration: 233° at 0.050" lift
  • Exhaust Duration: 240° at 0.050" lift
  • Cam Type: Hydraulic Flat Tappet
  • Surface Treatment: Nitride-hardened lobes for superior wear resistance
  • Application: Chrysler 273, 318, 340, 360 Small Block engines
  • Series: Nostalgia Plus — designed for classic muscle car performance character
  • Manufacturer: COMP Cams — USA-based performance camshaft leader

The COMP Cams Nostalgia Plus series is purpose-built for enthusiasts restoring or upgrading classic Mopar A-body, B-body, and C-body vehicles. This camshaft pairs well with COMP Cams' matching hydraulic flat tappet lifters, timing sets, and valvetrain components for a complete top-end upgrade. Always verify rocker arm ratios, spring rates, and retainer-to-seal clearances during installation.

First of all, I can not believe how fast I recieved my order, 2 DAYS! Best of all, the instructions made it easy for a non mechanic like me to install.

Fast shipping and the lowest price. Very impressed.

fast shipment and was exactly what i had ordered

Great Communication and instant shipping. Well done!

Had to upgrade to a Snell 2010 helmet this year, bought the identical helmet for $200 less than I paid 8 years ago! Fast shipping, I will be checking Autoplicity first in the future!
