I currently use an MSD 6A,an MSD blaster 2 coil and Magnecor wires.The reason I upgraded is because I'm using nitrous.If all you've got is just the bolt ons with no porting/polishing or forced induction than I wouldn't really worry about it and spend you're money elsewhere.If you really want to get it done than you might also want to consider a Jacob's ignition because they make them application specific for each vehicle.good luck.
