[Tigers] 67 MKII timing chain/gear question

[genepadgett at comcast.net]

Tom, do you or any other "Lister"', know if the unused mechanical fuel pump eccentric on the end of the cam at the upper timing gear is really needed? 

If you put in a double row timing chain, as I recall there is not room to also put on that eccentric without cutting it down a bit. Since the original motors came with it installed, I have always wondered if the cams may be somehow rotationally balanced with the expectation that eccentric is on the end of the cam. If so, it would seem a good idea to keep as much of an eccentric on the cam end as possible. 

Just wondering if anyone knows how important is that eccentric. Maybe like the human appendix?!

I'd recommend a roller chain. It is not much more and has the advantage of 
retaining the timing relationships longer. Many come with advance/retard 
keyways. If you would find that an advantage you have that option. Not that 
I've seen it happen, but a broke or loose chain has the potential to 
internally damage the cover.
