Line honing crank journals

A proper align hone job takes so little out its not even worth thinking about. The distance between the crank and cam centerlines will be reduced by a couple thou at the most. The factory machining isn't even consistent any way. When I built my left over parts 360 a few years ago it got a heavy line hone job. In spite of this the timing chain went on as tight as a piano wire. This chain had been used in my 340 for 6 years. When new it went in the 340 it was very loose about 15 degrees of slop, had to use the T chain tensioner. That motor had never been align honed.

As has been mentioned one can buy shorter chains for the cam to crank centerline issues, wish I had known that when I built the 340.
