Which MSD Distrb for my 355?

[Malibuysi]

After looking at the long list of options, I need a MSD Distrib for my 13:1 355? Anyone using one, what is the most widely used unit for dragracing and street use? Thanks

85551 or I used the 8570, they can have mechanical advance or flip a part and be locked out, or get the pimp daddy 8510
