Don’t let the title deceive you into thinking this write up being a parody of sorts for all the information contained within is basically excerpts from the camshaft manufacturers themselves and experts alike. I have spoken with numerous individuals that have considerable more knowledge than I regarding the subject matter, such as Larry Cavanaugh (Cavanaugh Racing heads), Plummen (truly, special gratitude to Larry & Plum), Timebomb, Mark1122, Sandy and Kawasakiman as well as others to pick their minds.
Basically I bugged the hell out of them until they gave me what I wanted to shut me the hell up!

Isn't that the lobe centers? There is a big differance. I'm not sure that I am understanding correctly.

" Where it has extremely wide to extremely tight. Is the heading correct?
I believe the heading to be correct, copied directly from the www.webcamshafts.com/ ... Glossary
The way I'm looking at it is as follows...
Mind you, I'm by no way an expert and don't claim to be!!!!
Based on the lobe center separation and in the information directly above it Varying Lobe Center Separation it would be considered Tight due to short range of 104 to 114 lobe centers.
Example, the OEM KZ camshafts lobe center is 110 degrees thus Broad Power band, reduced cylinder pressure @ 8.5:1, reduced max torque, etc...
With the 105 cam I chose, I'm doing the opposite where I'm shifting my power band more to the low to mid range, increasing my max torque but I'm also increasing cylinder pressures @ 10:1 etc...
Basically, a little quicker off the line and especially at mid rpm range...
Excerpt for Webcam... Not all motors can handle the tight lobe centering due to the mentioned....

I look at the closing point of the intake valve! To much cranking compression and you will be using race fuel. I like to lay out each possibile cam timing choice on paper so I can see it. The way I see it you have about seven timing choices.(advance both, retard both, advance int./retard exh., retard int./advance exh.,advance int./stock exh.,retard intake/stock exh.& stright up )You can find these choices on the net used by motorcycle drag racers, road racers and import car tuners.I have not seen anyone tune just the exhaust cam. Here is my example for three. I will use a stock Z1 cam.
L/C: Intake/Exhaust: Overlap: valve timing:
105* +5* / -5* 70* 35-65 / 65-35
106* +4* / -4* 68* 34-66 / 66-34
107* +3* / -3* 66* 33-67 / 67-33
108* +2* / -2* 64* 32-68 / 68-32
109* +1* / -1* 62* 31-69 / 69-31
110* stock timing 60* 30-70 / 70-30
111* -1* / +1* 58* 29-71 / 71-29
112* -2* / +2* 56* 28-72 / 72-28
113* -3* / +3* 54* 27-73 / 73-27
114* -4* / +4* 52* 26-74 / 74-26
115* -5* / +5* 50* 25-75 / 75-25
NOTE- If you find ANYTHING wrong with my homegrown hilbillie garage math "PLEASE, PLEASE" let me know so I can change my line of thinking.

Intake Cam
Exhaust Cam
Intake cam looks to be dead center, but the exhaust looks to be advanced quite a bit. These cams were on a ported head, with a 615cc engine that came in one of my parts bikes.
