I finally got around to spending 2 nights after 14 hr shifts to get this new tach installed. I would have never been able to do it if I hadnt snagged a FSM frm ebay. Whoo-hoo! This is what I am getting frm it.

This first pic is at idle in park.



This one is at 60mph.



Note the difference in the 2 tachs. I new the stock one wasn't correct, but I didn't realize how off it was. Both are getting signal frm the same wire. The shifts pts are approx. 1-2 @ 1000-1200 rpms, 2-3 @ 2000-2500 rpms, 3-4 @2500 rpms.

If this info is correct then I can move on to the cosmetic work on the old girl. Does anyone think this pics make sense?

that is good news, the original tach is definitely off, lol.

I would get a JY cluster and put it in. Your volts seem way low for 60 mph. Oil pressure is just where mine runs on the highway with the goofy sending unit.
I envy the full tank of gas.....Ha

looking for cluster already, the alt is only a yr old, but I'll have the advance guys ck it out and the tank only gets filled up maybe twice a month but thanks.
