Right now Im up in the air on what size MPS to use. Whether it be a 3.5 or 3.4 It should show too much KR with either with the supporting mods I have in place. The Hi-flow and possible flowmasters will wait till later. But other than that, I think Id be okay running a 3.4. Ideas? Also if anyone has the size numbers or can point me in the direction of part numbers for the corresponding belt PN or sizes.
