Rev limiting with a GM HEI module

Make sure you specify the MSD Soft Touch is for a Mopar ignition; I bought one only to find out it wouldn't work without modificaton by MSD. Can't remember what the modification cost; maybe $30 or $35 around 2004 or 2005 - it worked perfectly after they fixed it.

If you are interested in a used one; send me a PM as I sold the 70 Duster I had it on.

MSD's website says they make two models - the 8738 for use with it's MSD-6T and the 8728 for use with Ford and Chrysler electronic ignitions and the GM HEI large cap distributor. I believe I need to verify how to wire it up to a GM HEI module, not a MOPAR ignition.
