Advertised duration for F13, F14 and TSP 233/239
Hey guys just wondering if you can tell me the advertised duration of these 3 cams. I'm torn between the three-losing sleep actually-it's pretty sad.

I have a F13 in the for sale section with all the specs listed. Here is the link

Wouldn't a faster acting lobe provide more low end vacuum which would in turn provide better driveability? It's seem like the F13 is very close to a XE lobe profile.

If you leave the same .050 duration and raise the .006 duration, you weaken the intensity of the lobe. For example, XE-R lobes have a seperation of 49 between advertised and .050", TR and Futrals are around 50, and XE's are 53, then some of the lunatis are 58 and 61. The higher the diffrence, the softer the lobe ramp.
