What is the recommended break-in procedure for this camshaft?

Proper break-in is crucial for hydraulic flat tappet camshafts. You will need to run the engine at 2000-2500 RPM for 20-30 minutes immediately after installation to properly seat the lifters and prevent flat spotting. Always refer to the manufacturer's specific break-in instructions for details.

Does this camshaft come with new lifters?

This camshaft is sold individually and does not include new lifters. It is designed to be used with compatible hydraulic flat tappet lifters. It is highly recommended to replace your lifters when installing a new camshaft to ensure proper performance and longevity.

What kind of idle can I expect with this camshaft?

For 454 cubic inch engines, this camshaft is designed for heavy towing and will provide a smooth idle. For 396 cubic inch engines, expect a slightly rougher idle due to the camshaft's performance-oriented specifications.
