All I can find is a home page for Delta- - - -no product listings. Do they show timing and lift specifications for that "252" cam anywhere? 252 degrees of duration is very similar to the Elgin cam we put into John's 261 last year. It was a solid lifter grind, however. Elgin advertises it as a "290" duration, but they include the clearance ramps in their duration numbers, when the valve is actually still closed. I seem to remember the actual "valve open" numbers being somewhere in the 250-260 degree range when we checked the cam with a degree wheel.
