LT1 Optispark/timing issues

[67goatman455]

okay, cam gear dot at 6 o'clock, and crank gear dot at 12 o'clock. you need to verify that you have those lined up correctly first, and that your not a tooth off. Now when looking at the OPTI where the cam dowel pin will fit into, there are 3 narrow slots. One slot will look different than the other 2 (pointed out in the diagram posted earlier) http://shbox.com/1/opti_back.jpg

You have to be dead certain that the dowel pin went into the correct slot, and not into one of the circular depressions. When installed correctly the mounting points on the opti will sit completely flush with the front cover. If there is a gap then you most likely dont have it installed correctly. With new o-rings on the opti, I usually have to use more force than i would like to for it to slip into the cam.

one last thing is that you dont need to pay attention to where the opti is oriented, the timing is not manually adjustable at all in any way, as long as you have your timing chain installed correctly, and the opti is lined up correctly, then everything is set up fine.

Im just trying to lay it out completely just incase you might have overlooked something.
