Jezel timing set Is their a adjustable Jezel timing set that is that isn't for race only? Has anyone run one. Do you need to pull the UD pulley to do the adjustment. I spoke with Jay at Abusolute and he told me that the Comp set up you have to remove the crank pulley to do the adjustment.
And last who carries them.
I'll do a search and see what I can find

How tight would the seal have to bee if I modified a stock cover. I am waiting to install a ATI super damper with a H/C package. The cam is being ground with some advance in it. I wanted to be able to play with the advance without having to yank the pulley off

Change cam timing with mod timing chain cover on Hi,
I modify the stock front cover the first time I take it off so that I can change the cam timing without removing the cover using a Comp/Cloyes gear:
To modify the cover:
Drill a hole in the stock front cover big enough to fit a 10mm socket.
Place this hole on centerline and in front of one of the cam bolts when it is in the 12 o'clock position.
Cover this hole by gluing on a thin (~0.060”) aluminum or sheet metal plate using silicone.
To change the timing:
Remove the water pump
Cut the glue to remove the cover.
Loosen one cam bolt at a time as you rotate the engine.
Vette’s need to rotate the engine using a 15/16” offset box end wrench.
When the bolts are loose, adjust the timing using an Allen wrench.
Tighten the bolts & check the timing mark
Glue on the cover
Good lick,
Steve

Great idea, the hole. Might be able to find a rubber plug even.
What about Comp's instructions to have no load on the cam when you adjust it?

"Might be able to find a rubber plug even."
There is very little room between the cover and the water pump. That is why I ended up with a thin plate glued on.

After you get the cam bolts loose, you need to turn the crank as you hold some pressure on the adjustment hex. The hex is not strong enough to turn the cam.
Good luck,
Steve

They mean for you to losen all the rockers to take the spring presure off of the cam that way it moves freely and does not move on it's own. Due to the downward force put on the lobes by the springs ETC...
