Timing Gear Drive

That's correct. The only way to know where to put it is how you end up installing your cam and where it works best.

I am going to install mine at 106. I'll have to get my dial and wheel on there and see where it sits. Someone on here was able to do it without offset bushings, so It SHOULD be doable.

But yeah they are all different positions.

I was able to get my 106 degree centerline without any keys. It does take some time and I had to move it a few times to find the right combination. I now have almost 2,000 miles on mine and have no issues. This has been a great thread.
