OK, for those of us running the Mopar electronic distributor and orange box, can you make the factory tach read accurately?

No...
On my 70RR, I swapped out the Tic/Tac for a tach using the VDO insides from RedLine. RedLine custom makes a front plate using the same fonts as the OE Mopar so it matches the other guages. My ignition system is the Mopar electronic distributor and chrome box. I also have run an MSD box without issues except the tach is driven from the MSD box rather than the coil.

Just my $0.02...

Thanks but I already paid $425 for the tach from Charger Specialties (plus duty, shipping and exchange so probably really about $750.00). I can't see ripping it apart and paying another $300 - $400 so I guess I'll just go by ear for now. ....maybe a hidden rev limiter for safety..

Dave..
The tachs from Charger Specialties have later internal electronics in them, so they are compatible with the older point systems, Mopar electronic systems, MSD and most
aftermarket ignition systems.

Thanks, I was wondering about it's accuracy and I ASSuMEd that it was an accurate repop of the originals...I'll maybe check it with a friends spare from his racecar but sounds like I may be good to go!
