This one will bump the number of cable rotations by about 13% (1.1333). My speedo presently reads slower than my actual speed as measured by a GPS receiver by about this percentage (53 mph when driving 60). I've got 33" tires, 3.73 gears, and a TH350.
I've got one with the same ratio as yours and another that's about 1.2 or so. I bolted one onto my K20 that was about 1.3 and that got the speedo dead accurate. Got lucky there.
