Default Thoughts on this cam?

Im lookin at gettin this cam. Any thoughts positive or negative on it? https://texas-speed.com/shop/item.as...d=167&catid=44 Also, im debating between gettin the lobe at 112 or at 114, my goal is to still be able to use it as an everyday driver. With this cam i was planning on gettin 918 springs and hardened pushrods... Any thoughts?

I'd say it's a litle big for an everyday driver with the stock stroke.

The one I'd sell is a custom grind
268°/272° @ .006"
222°/226° @ .050"
143°/147° @ .200"
.340"/.340" Lobe lift
.578"/.578" Valve lift
110°/118° L/C

A little big? The one you spec'd is bigger (in terms of idle quality). Your grind has more overlap (4 degrees more) than the one he wants on a 114.

You may not be looking at his custom cam the right way. In layman's terms, it's:
222/226 114LSA (+4)
-4 degrees of overlap at .050"

The TSP 228/228 cam has +4 degrees of overlap with a 112LSA and 0 degrees of overlap with a 114LSA. Both of these cams would be harder to tune and less desirable for a daily driver (although they're still fairly tame).

110 is the intake centerline. 118 is the exhaust centerline. 114 is the lobe separation angle and the cam is ground with 4 degrees advance (hence the 110ICL).

Patrick had it right.

L/C = Lobe Centerline.

When designing a cam, I calculate the Lobe Centerline for the intake and exhaust valves. We grind it at the lobe Seperation it takes to give me those Centerlines.
If the Intake Centerline needs to be a 108, and the exhaust needs to be a 118, we would grind the cam on a 113LSA with 5 degrees advance.(BTW, when you advance the cam, the Intake L/C gets smaller, and the exhaust L/C gets larger)
