Adjust curve 440 Source distributor?

That Distributor appears NOT to have a VA on it,
making it NOT street friendly, and especially not hi-way friendly if that matters to you. But it works well enough with a higher stall convertor.
Personally, I am a big fan of VA and run 22* in mine.
Actually does matter quite a bit. I bought this as the quickest easiest cheapest way to get this motor running before winter.
