Not sure why yours would be different? I run the tack off the plug on the MSD box instead of the coil. Hmmm. In my 70RR, I tried running my MSD 6 with the Mopar electronic distributor and the OE tic/tach worked but was way off by about 40%. I swapped out the OE tach for one from Julius worked fine and is dead nuts on for calibration... Just my $0.02..
