All,

Has anyone been able to get a 240 tach to work with the d2 distrib?

Thanks,

Yes, it isn't impossible just a bit tricky.

You'll be removing the resistor by the coil, and reconnecting the tach slightly differently. Big thing to remember the 240 tach MUST be part of the circuit in order for the coil/dist to work.

I read several postings here and other sites, I'll pull out what I used and post.

I will be running a dedicated hot (switched) lead to the coil and distrib, so the tach out of the circuit should be ok,

Dont think so. The circut has to go throu the tach . You can get a tach from a late 73 or 74 they will work mine does. Other wise get a unit from a later 280 and put the works into your tach's housing and use your old face so the red line stays the same . when you pull the needle be careful and reinstall with rubber cement so if you ever have to take it apart you can.. Good luck Gary Portland Ore.

This was the posting that helped me get my dizzy and stock 240 tach finally working properly. I give HUGE credit to JohnH240 for his step by step on getting the tach to work. Read it carefully, you CAN make a stock 240 Tach work with the 79-83 dizzy, I have one and it's working.

This has some EXCELLENT advice and also a powerful discussion on performance tips in general. The author there, however, prefers to swap out a 280 Tach into the 240 Body.
