Degreeing aftermarket cams

Here is my starting point:
'74Z1A; Wiseco 1015cc, 10.25:1CR pistons; Kenny Harmon D grind cams; complete Dyna S ignition; slotted cam sprockets.
Where the hell is the starting point for this set-up?
The time has come to "degree in" the cams but I don't have a clue as to a starting point.
I even bought a cam degreeing dvd from Dale Walker's Holeshot Performance, but he seems to be degreeing an engine that is already set up!
This project is approaching FOUR YEARS OLD! I really need to get this Z on the road. I now have a CB550K and a CB200T that I want to 'cafe", but I must get this project up and running before I get involved in another.
Is there a thread here that I have overlooked?
I'm depending on you guys for your help.
Remember, I've been in the wine and liquor business for over 30 years. There ARE perks, you know! Not that I'm trying to bribe anyone or anything.:whistle: :whistle:

You'll need that info before you can do anything with those cams,bud.
I had a friend of mine help me with mine,and ya...it is quite a process,but for him it was easy,as he had done it many times before.
You'll need a degreeing wheel,and a top-dead-center gauge.
Anyway...the specs will be something like the attached pic...
(sorry I can't be more help)

just lack the know-how.
I'm ready to give up on those cams and go with something else. Hell, it's only money, right?:whistle: :whistle:

But I recall the Holeshot video being fairly helpful actually, if you ignore the fact that he's dealing with a drag bike. The cam math isn't bad and fun really, once you wrap your head around it. One step at a time, keep checking the video...
One problem I had, though I have oversize valves, was the positive stop tool could make contact with the intake valves. Also, you hafta fool around to make the dial indicator clear everything -- maybe bend the extension a bit to get around the cam. Make yourself some kind of steel plate fixture bolted into the valve cover holes to firmly mount the magnetic dial indicator. One other thing: I recall preferring to use the ignition side of the engine for mounting the dial to avoid taking off my leaky generator cover again.
Overall advice: If the engine doesn't seem to wanna turn, STOP!! Look things over again.
I'll poke around and see if I have any helpful links. But check that video again, get yerself setup: valve cover off, cam sprockets somewhere about the middle of the slots, standard cam mounting procedures to start (by the manual), get cam caps bolted down in approx. stock timing (your sprockets marked?), mount the dial, make an indicator needle, etc., etc., etc.

why dont you just mic the lift and find out for sure?
That's a good idea,and a good start.
What's the base circle measurement?I'll have to look that up again.
We could try that,Jim...and compare?...:huh:
(110 base circle)
