WKMCD | 10-16-2012 04:42 PM | So you're looking to run 1.08 inches of lift at the valve. I think you have your terminology mixed up.
Your cam will have .347 of lobe lift. With standard 1.7 ratio rockers you net .588 inches of lift. With 1.85 inch rockers your lift at the valve will be .641. That being said, lift has almost nothing to do with piston to valve interference since max lift occurs when the piston is near bottom dead center. Overlap is the factor you need to take into consideration. For that, you need to post accurate durations and lsa. It's always best to clay the engine. |
