I’ve just been looking and don’t see a lift spec in the manuals. I’m sure you can find one. I’m guessing you went with the CS-364 camshaft that D&D sells. They’re really knowledgeable. Whatever they told you on it is likely accurate. Mine is the 50230 (D&D part number) – Crower 260 degree 446 lift. I have had noise issues I finally pinpointed (I think) to my Crower lifters, so write if any questions.
