Description: The Street/Strip camshafts for Honda/Acura B-Series VTEC engines provide best performance up to 9000
RPM. They are ground from chilled iron and nitride hardened for outstanding durability. Due to the increased lift of these
camshafts, changing valve springs is required.

Recommended Related Products:
Due to the high rpm nature of the Street/Strip Camshafts, a programmable or modified ECU is recommended to overcome
the rev limiter for off-highway race vehicles only. Fine tuning on a dyno is recommended for maximum performance. We
recommend the use of Edelbrock Adjustable Cam Gears, #4721 (silver) or #4723 (red), to adjust cam timing for best
performance.

INSTALLATION NOTES
•
Note: Make sure your engine is in good running condition before installing the Edelbrock Street/Strip Camshafts. If your
engine is not in good working order, installation of these high performance camshafts could result in premature engine
wear. It is recommended to check the wear of the camshaft journals before installation by checking the oil clearance as
shown in the factory service manual. Checking the camshaft end-play, and rocker arm wear is also recommended.

•
Remember: When working on your engine, especially when oil or fuel is present, always work in a well-
ventilated area. Keep all sparks, open flames, or other sources of ignition away from the work area. Failure
to do so could result in a fire or explosion causing vehicle or property damage, personal injury, and/or death.
•
Before Beginning: This installation can be accomplished using common tools and procedures. However, you should have
a basic knowledge of automotive repair and modification and be familiar with and comfortable working on your vehicle. If
