anyone using a HEI distributor..anyone tried skip white one

There as a bunch of us running HEI, and the skip white distributor is one of them.
Everyone I have seen or heard about using the skip white unit seems plenty happy with them, although the lifetime of them is kind of up in the air still. (probably a good sign) :-)
Some of us run home built HEI using the four pin GM style, and I myself run and sell kits using the 8 pin GM style with weatherpak connections and they work great also.
The home built and the kits I sell both use the OEM Mopar distributor.

Here's mine, mounted on the drivers side of my brake booster but they can be mounted pretty much anywhere incuding under the dash.

My own kits come with the HEI Ecoil also, that runs a .050 plug gap.
Literally everything you need to switch is included in our kits, so if you decide on the Skip White unit keep in mind that you will need to buy a new coil also or it won't be HEI.
