It's a pretty healthy cam. The 3318 and the 3319 are the lobe numbers, which translates to:
248/254, .638/.658" lift (with a 1.7RR) and it was ground on a 112 LSA.
These are Xtreme Energy lobes and I'm sure it was a custom cam as the Xtreme cams don't come with a longer LSA like that. I've had Comp send custom cams with the LSA equalling the ICL (straight up) and then I've had them send them 4 degrees advanced, so it's hard to say without degreeing it where the ICL actually is on yours.
I like that kind of combination, a good amount of duration, but a longer lobe center to help with low manners. However, that's a lot of duration for a hydraulic roller and I don't know if you'd really be able to use most of the cam's potential without floating the valves.
Are you still planning on swapping to a solid roller? Or you want to stay hydraulic?
