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

I have the standard Skip White GM large cap style on my 351M Ford engine. I was not happy however with the advance curve on the Skip White unit as it came, so I recurved it with a $4.99 kit that included weights, a new cam, springs and bushings. I ended up being able to use the lightest springs, because these engines were low compression. It made a tremendous difference when recurved, although I noticed a nice difference even before with quicker starting. Trailbeast has it down for the Mopar stuff......I may end up doing it on my rat truck, since I have adapted the 331 Hemi to use a small block distributor. It would be a really simple install, too.
