Product Details

The COMP Cams 11-734-9 is a high-performance solid roller camshaft specifically engineered for Chevrolet Big Block engines ranging from 396 to 454 cubic inches. This drag race camshaft features aggressive 276/284 duration specifications designed to maximize horsepower and torque in dedicated racing applications.

Key Features:

  • Solid roller design eliminates the need for break-in procedures and provides maximum valve control at high RPM
  • 276/284 duration profile delivers strong mid-range to top-end power for bracket racing and drag strip performance
  • Specifically ground for Chevrolet Big Block engines (396, 402, 427, 454 CI)
  • Requires aftermarket solid roller lifters, valve springs, and retainers (sold separately)
  • Ideal for racing applications with loose converter (3500+ stall) and numerically high rear gears
  • Precision-manufactured from high-quality core materials for durability under extreme racing conditions

This camshaft is intended for dedicated racing engines with supporting modifications including cylinder heads, intake manifold, headers, and valvetrain components. Professional installation and proper valvetrain setup is required to ensure optimal performance and reliability. Not recommended for street use due to aggressive profile and idle characteristics.

This was my first purchase from Autoplicity, I bought a HyperTech tuner for my truck, they had absolutely the lowest price of anywhere I looked by far. Only thing I could fault them on is that it took 3 days for the product to ship, a little bit long I feel for something that was in stock, but Ill overlook it since it was such a great price.

OK so far.

Autoplicity was quick, and fast! the shipping was standard but arrived in five days! I would definetly recommend them!

Good prices
