Cost of setting timing, on a V8 ??

I think you may have started to scratch the surface there...

I could have written a post that would take me all day to write.

But then, some guy comes in, doing it in his home garage a lot cheaper because he doesn't have the overhead to pay. It's all beer money for him.

The other guy is paying his bills for the shop and all his household bills hoping he can break through and make a go of it.
