racer88 Posted December 8, 2009 Share Posted December 8, 2009 Hi everyone This is my first post on this site. I am new to z cars, but built and raced late model stock cars for 20 years. ( I have seen the light) I have searched for info on tach problems when you convert to zx dist. and a gm module with no luck on my year of car. I installed an 83 zx dist. and a gm module in my 260. It runs great, loads of spark but the tach does not work. I have read all the fixes about the 240 tachs but my car is an early 74 260. My question is are the early 260's the same as the 240's or is there a different fix. Any help would be great Thanks Bob Morris Quote Link to comment Share on other sites More sharing options...
