A little more lift and duration then the 261 cam, but with a pretty smooth idle. Clifford used to sell a very similar cam and advertised it as having a smooth idle. Schneider did a terrific job with the cam in the one 261 motor I have, even after I messed it up. And boy, have I put that motor through its paces the last couple of years. I obtained another cam from them because of my experience with the quality of the advice I received and the product.
