Not seeing it... crane has more EXHAUST (234 vs 230) timing and lift, but a little less on the intake. Alright, I don't have the .200" numbers but I can't see there being a vast difference on a hydraulic at this level.
No, I said timing events. You're quoting duration figures. that particular Crane number opens the intake valve WAY early and closes the exhaust valve WAY late in comparison to anything else close to it other than some rollers. I don't know why. But that's how they ground it. As a result, it makes cylinder pressure skyrocket. I've used it in several different small blocks with excellent results. In fact, Dick Landy Indutsties used that same grind in a 400 Chrysler buildup in Mopar Muscle years ago and got well over 400 HP from it just to show what could be done with a basically "stock" 400. Stock meaning factory iron heads. They did use the KB240 I think it is piston. I don't remember if that's the number....I think it is. Whichever one gets the compression up to like 9.2. Crane has always been known for grinding camshafts on a bit less of a "cookie cutter" basis than comp. I mean Geez, go through the comp site. You'd think they don't know any other lobe separation other then 110. That's just stupid. Crane has so many different grinds compared to comp there's no comparison. Now, if S&S Cycles will just get cranked back up to full capacity, they'll be on to sumthin.
