All of our street/performance cams are daily driver friendly with gentle opening ramps for good idle and transition with no lag or flat spots. Our custom designs have progressively more top end. (82-89 USA SPIDERS WITH BOSCH EFI MUST DO WITHOUT VVT FEATURE.)

This #445 12.0mm lift cam is a very special Jim Kartalamakis design.

Installed as INTAKE CAM with 11.0mm SA424 EXHAUST CAM, the broad smooth power band makes it very popular for street performance, as well as rally and vintage racers. This combination is renowned for both remarkable low-end torque and top end. Duration @.050″ 266 degrees. Base circle diameter Standard 1.075.

NOTES:

• All new cams should be installed with new followers. We can only guarantee our cams when installed with new set of Spruell Motorsport followers.
• We strongly recommend upgrading to VSS13 springs for 11.6 and 12mm lift cams.
