in addition to what is said the post before this, MD has done a lot of R&D work and makes both a 5/16" and 1/2" spacer. Each having its own area of power gain. The 1/2" making more power in the top end and the 5/16" making good power starting in the mid-range. Blox is a 5/8" and is believed to be too large to make usable power for every day driving, as it seems to only add power at the top end.
