Please check notes in each part listing to ensure the Rocker Arm is correct for your 1967 GMC P25/P2500 VAN with a 4.1L 250 engine. SEALED POWER & ENGINETECH are competing brands, and each brand's Rocker Arm may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Rocker Arm fits only certain 1967 GMC P25/P2500 VAN models.
Clicking a "More Info" link will display a picture and/or other details about that Rocker Arm in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Rocker Arm, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Engine parts, other GMC P25/P2500 VAN parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1967 GMC will not be lost if you switch.
