Anyone tried one of these HEI Distributors?

I ran the same distributor on my stroker motor, it worked just fine. I ran it with an MSD Blaster coil and a 6al box. If the 6al is going to be hooked up, you will need to take the ignition module out of the little chrome box t the base of the distributor. The one I ran had a very fast timing curve; it would add ten degrees starting at 1500 rpm and be all in by 1750rpm. I pulled mine and put an MSD Pro Billet dizzy in. any difference? Nope, it ran just like the MSD, although the MSD is very easy to adjust the curve.
