I think its smaller than 480 - maybe as small as 380, but the fins make it a direct 540 fit. In cars like the CAT SX where the motor is clamped the Ezrun fits perfectly
Mtroniks did do a motor which was actually 480 sized, and bolts onto a special plate to make it fit 540 sized screw holes, but this is totally different from the Ezrun in design. I also don't know how it would perform having never seen one in use.
Just fit the 5.5t Ezrun. At least that will fit, I know it works etc.
