I've found a slightly used timing belt that was used in a ATX sho. I was wondering if it can be used in my MTX sho? Thanks

Yes, it will work. The belts are the same physically.

The "ATX only" belt has the white timing marks on it for the ATX setup and are very helpful in correctly installing the belt. Perhaps your found belt has both sets of marks.

FWIW, the Gates T248 has markings for both and is less than $40 brand new.

If you are able to install a timing belt, don't waste the time installing a used belt. It is the stretching of the belt that costs power from the loss of camshaft timing. Use a new Gates T248 for a whopping $34.77 from RockAuto.com.

The overall belt lengths are the sanme, but the ATX has an idler pulley on the forward side of the belt that makes the belt route from the front bank camshaft pulley to the crankshaft pulley one belt tooth longer than with the MTX. Hence the difference in the white marks at the crank pulley.
