I am selling a MSD DIS-2 ignition amplifier and the tach adapter. This is in used but good/working condition. Included are all the components one would need to install this on a 2GNT. This device is capable of:

1. Retarding spark by a constant or RPM-variable amount
3. Slightly improving idle smoothness/quality
4. Allows the use of a slightly larger spark gap (in theory)

$175 shipped.

This is not a picture of the actual item - this is an image I found on Google Images.

Any chance of selling that without the tach adapter? I already have one from my portfueler kit

Sure, but the tach adapter is only worth about $25 used, so the total without it would be $150 shipped.
