Default Setting proper timing using timing light (adj. cam gear and milled head)

I have a d16y8 block with a d16z6 head. I sent the head to be milled 0.040" and when I got it back I realised the head had been milled a good amount before, at least 0.020". After I put it on my block I used my oem z6 cam gear. The car was very slow below 4000 and pulled hard all the way to the rev limiter. I maxed out my timing on my distributor and the car ran better, but still was very sluggish below 3000 rpms. I grinded the holes on my distributor to advance it a bit more and car pulls hard, ran 15.1 @ 89 mph in a 4 door EF but I feel it isnt at its best.
I figured the best way was to get an adjustable cam gear and strobe light to check timing. I have an adjustable cam gear from 96-00 and a base model strobe timing light. I know I have to advance the cam gear 4.75'' to compensate for the difference between z6 and y8 cam gear.

How do I set correct cam timing with my strobe light?
do I have to loop the connector on the passenger side under the dash?

I have access to these manuals but it doesnt show, anybody has a link to better manuals?

are you asking how to use the timing light or what timing to set for your specific motor setup?

You have to get the mechanical timming correct .then do your spark time.Without knowing how much was taking of the head exactly you can only guess at what to set your cam gear at.Maybe try a search to see where the stock cam is degreed at and degree your cam.That will set your base time correct.Then you ignition timing can be set by light.If not search and find how many deg is changed in mech timming per thou of an inch milling.And set your gear from there.Good luck.

Thank you for the information.
So the only way to set proper mechanical timing is by degreeing or can I ''guess'' it and check it with my timing light then make adjustments?

y8 cam w/ z6 sprocket, z6 cam w/ y8 sprocket

You need to retard the 96-00 adjustable camgear, your setup is basically a Z6 head with a Y8 adjustable camgear....

First, adjust the camgear timing, second adjust ignition timing!
Check the Page 23-105 of the 96-00 service manual to adjust the ignition timing!

I know this is a really old post but I'm trying to figure out pretty much the same thing. I have a z6 block I'm putting a y8 head on. I have the y8 cam and a vms adjustable cam gear from ebay that says it's good for the d16z6 and d16y8. I'm trying to figure out what to set the adjustable cam gear too? Any help is appreciated!

Start at 4.5deg advance, just like the upper right hand diagram in the cam timing post above.

If the block or head has been milled then advance ~1 deg/ 0.012" milled.

That will get the closest, degreeing the cam would be a good idea it is not a stock y8 cam.

Its one degree per mm or 39 thou. Hence the 5 mm difference on d15 blocks need 4.75*

Omg the guy who bumped this thread is fucked. I told him what he need. He has a y8 snd a d16 block he needs a y8 cam gear to go with his y8 cam. he doesnt know enough to argue. For fuck sakes.

Also i already explaned to you about your gear.ok it fits on a 88-00 cam but the 96-00 cams are keyed differen... so the marks for your cam are set around a 88-95 cam. So to use it with a 96-00 you need to set it advanced 4.75* witch in turn makes the adjustable cam gear a oem y8 gear. Witch is what you need. You match the cam with the cam gear unless you are changing deck heighs of your block.

This is too simple. Its been covered 3500 times. Why would you need an adjustable gear? Answer that please. Once you know why you use one you will understand why you dont need one. Stop posting shit. Your reading threads from 2009. If it isnt from 2013 keep searching. All this have bee covered corectly in the last two year more then 500 times. I know for a fact i answered this 65 times in the last six konths.

Forget you have a z6 block its the same fucking thing as all sohc blocks. You cought up on the wrong thing. The block is the same as a y8 and a6 but with different dip stick locstion and knock sensor. Why the fuck do you need an adjustable cam gear if only the dipstick and knock sensor are different?
