508 or 509 Purple Shaft cam

Yes at one time there was two. The 292 - 108 version might not out anymore. They were coming out with one with better vaccum. But i have seen one. and i dont remember the centerline on it. More than 112 i think. When i put my last 340 together thats what i ran into. So i used the comp cam 508. Split dur 292/299. I like it .
