Frequently Asked Questions
Can I use the stock starter with this cam?
Yes. The Easy Start profile is designed specifically to allow stock starters to crank the engine without upgrades.
What compression ratio do I need?
Minimum 11:1 compression. Engines below that ratio may not achieve the intended performance and durability.
Does this cam require engine modifications?
No special modifications — the cam bolts into stock Dyna Easy locations. Installation kit is included.
What RPM range does this cam perform in?
Peak performance is in the 4500–6500 RPM range, ideal for mid-to-high revving street and strip riding.
Why is gear drive better than a timing chain?
Gear drive eliminates timing chain lash and stretch, keeping valve timing precise and consistent across the RPM range.
