I know what they say about opinions, but i am having some indecision paralysis regarding a cam, and if i can't ask here, where can I ask?
It also meshes with another post on LSA.

So, i have put this together twice with flat tappets cams that have failed in the first 100 miles.
I am determined to avoid that again and going hydraulic roller this time.
I contacted Howard and filled out their cam recommendation form and waited a week and they came back with their #711915-12 hydraulic roller cam.
Specs:
274-278 advertised
221-225 @ .050
474-500 lift at 1.5
112 LSA
Operating range 1200-5700
Mild idle, low end torque, 9.5 comp required
In at 108°
Now summit only had 3 roller cams of any type available available, and that happened to be one of them, so i am not sure if that is the best choice, or just the best choice of what is available. I asked for the intake valve abdc number to plug into wallace to determine dynamic compression and cylinder pressure, but have not heard back yet, and not found anything online.
Anyway, I guess I had in my mind something like a BTR cam with lower duration, more lift, and and tighter lsa, like their 107.5 lsa 112 duration, and over .550 lift.
Opinions? anyone run this cam?
