    Edelbrock part #7157 Performer RPM Camshaft is designed for Pontiac 350-455 V-8 applications. This Edelbrock cam kit produced 422 HP & 441 ft-lbs. of torque when used with #7156 intake and #60599 cylinder heads on a 455 engine. The camshaft works well with high-performance's street applications, Performer RPM cams provide power from 1500 to 6500 rpm. This hydraulic lifter camshaft is dyno-matched to Performer RPM manifolds for high-rpm horsepower while still maintaining acceptable low-end torque. With 10 to 12 inches of manifold vacuum at idle, Performer RPM cams have more lift and duration than most street camshafts. Hydraulic flat tappet lifters are included with each Performer RPM camshaft.

    Shipping Policy

    Cancellations

    Once an order is placed, in most cases it cannot be cancelled as they are sent for fulfillment almost immediately after receiving the order. If there is an ability to cancel the order, the buyer is responsible for the transaction fees charged from the transaction.

    Processing Time

    In-stock orders are typically processed and shipped within 1–2 business days of receiving payment, unless otherwise stated on the product page. Orders placed on weekends or holidays will be processed on the next business day.

    Shipping Costs

    Shipping costs are calculated based on the shipping method selected, the weight and dimensions of the package, and the destination address. You can view the shipping costs for your order during the checkout process before finalizing your purchase.

    Tracking Information

    Once your order has been shipped, you will receive a shipping confirmation email with tracking information. You can use this information to track the status of your package and monitor its delivery progress.

    Delivery Time

    While we make every effort to ensure timely delivery, please note that delivery times may vary due to factors beyond our control, such as weather conditions or carrier delays.

    International Shipping

    For international orders, please be aware that customs duties, taxes, and other fees may apply upon delivery. These additional charges are the responsibility of the recipient and are not included in the shipping cost paid at checkout. Please check with your local customs office for information on potential fees before placing your order.

    Please ensure that the shipping address provided during checkout is accurate and complete. We are not responsible for orders shipped to incorrect or undeliverable addresses due to customer error.
