With 1.72 rockers it will be at .516/.516 lift. A nice place to be I think with the spring pressure I’ll likely use to keep my pedestal rockers reliable.  The duration on that cam is high though 280/286 advertised,  220/<a href="mailto:226@0.50">226@0.50</a>. I do wonder how my piston to valve clearance will be as I’m using stock pistons . Also I wonder what effect 1.72 rockers will have on how that cam behaves, quite a few people say it’s a little soft below 3k rpm when used naturally aspirated. It was also designed for use with 1.6 rockers I believe, but I’m unsure what makes a cam designed for one rocker ratio to begin with. That was kind of my initial question.The Crower 15511 is also high on my list 278/282 advertised, 218/224@.050, .503/.522 with 1.72 114LSASeems similar to the Steeda #19, but perhaps less soft down low.</blockquote>
