what distributor is this?

Ningboa is the Chinese manufacturer. Skip White Performance of TN is one ebay seller, and usually the cheapest. I recall $65 for BB and $45 for SB engines. Slant owners are still waiting for one. It should give a spark similar to GM's HEI, so not a bad term to use. No ballast resistors are used with modern ignitions, c.a. 1980+. Mopar had similar, but integral with their notorious "spark computer" or "lean burn".
