Product Details

The COMP Cams 34-812-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Ford 429 and 460 cubic inch big block engines. This aggressive grind delivers maximum power output with 289 degrees of advertised intake duration and 320 degrees of advertised exhaust duration, optimized for high-RPM operation and straight-line acceleration.

Key Features:

  • Solid roller design eliminates valve float and provides consistent performance at high engine speeds
  • 289/320 duration profile delivers strong top-end power for competition use
  • Engineered specifically for Ford 429 and 460 big block V8 engines
  • Precision ground lobes ensure accurate valve timing and lift characteristics
  • Race-oriented design maximizes horsepower and torque in the upper RPM range

This camshaft requires compatible solid roller lifters, upgraded valve springs, and proper valvetrain components to handle the aggressive profile. Intended for dedicated race engines with supporting modifications including ported cylinder heads, headers, and high-flow intake systems. Not recommended for street-driven or emissions-compliant vehicles.

I just ordered and was fast.. just waiting to see how long they take to arrive

east to find. exactly what i need

So far good Fast shipping. Order was as expected

Autoplicity must have sent my Airaid CAI within hours of my order because UPS delivered it right away. I even got it before I received an e-mail indicating the order had been processed or a notification of shipping e-mail. <br><br>The online advertised price seems to vary by about $20 and that means that you must monitor the site if you are to get the lower price. However, Autoplicity has arranged with BuySafe to give you the difference if you establish an account with them and go through the process. This process was not easy as there was an apparent database problem where the Autoplicity URL was not taken by BuySafe. A call to BuySafe got that worked out, I am hopeful that I will receive the refund promised via paypal. It looks like a good system if it works.<br><br>The bottom line is that Autoplicity offers the best online price by far and although my unfamiliarity with how they do things caused some confusion on my part, they do have a good order processing and price guarantee in place.
