Is it possible to screw up a nonvent opti install? I always over think things.
This is my first LT1 rebuild and I have the 93 nonvent opti.
I assumed the keyway on the shaft could only line up one way and that was it. And now that im over-thinking things is it possible that i could have it 180*out. I didnt note the dowel loc. or timing marks when installed the opti. Is there an easy fix or Does it make a difference?
I thought one revolution of the cam = 1 rev. of the opti. But that stupid book has the vented in it and its screwin with my head.
I did a search and there is tons of info on the vented but not the Non-Vented opti.
BTW this is useless

I have found that if it is installed in the wrong hole that the distrib. doesn't mount up flush. There is one hole on the distrib that is longer than the other 2 and it has a tip cut in the top of it. That's the one. Good luck with your build. The only thing you should have 2nd guessed is the use of the sealed opti v/s the vented. That could haunt you.
