Jason.........in addition to the differences mentioned above, track crank chainrings, cog, and chain are all 1/8" thick.......as opposed to 3/32" for road. But other than that, with most road cranks, mounting the chainring on the INSIDE of the spider will generally result in better chain alignment........that's if your chainring is small enough to clear the chainstay. I'm assuming your chainline right now is way out (outward).
Since you already have a Sugino BB, a Sugino track crankset should do the job also. Generally speaking, it's best to have matching BB/crancksets.
I'm using a Campy track crankset with a Shimano bottom bracket, but had to experiment with a couple or three BB spindle lengths to find one just right to achieve perfect chainline. I just happened to have several Shimano BB of varying lengths in my junk drawer at the time. But on the other hand, I don't think a Shimano crankset would work with a Campy BB. The crank would just bottom out at the spindle taper, therefore not compatible. Thank you!
