Hi there,

There are a bunch of less-complicated solutions to this problem. I have a
1960-vintage Detroit 6-110 which has issues similar to yours. Two solutions
which I have used are:

1) Use a mechanical tachometer. My engine room tach works just fine, it's a
NOS (new old stock) Stewart Warner I picked up on eBay. I was also able to
pickup up the right angle 2:1 drive and the flex cable on eBay as well. The
drive tip was $2.50 at my local truck shop.

2) Use a programmable tachometer with your alternator. I have effectively 3:1
drive on my alternators (2:1 in the engine and 1.5:1 in the belts). The VDO
makes a programmable tach (model 333-162) which you can set for any pulse
train. It takes about 10 minutes to calibrate, especially if you have a
mechanical tach to use. I also picked up a Veeder-Root hand-held digital tach
on eBay, it's great for troubleshooting all manner of mechanical devices. 

Hope this helps,
