I replaced my tensioner pulley with one for an LT1 motor. It doesn't have the guide rims on the outside edges of the pulley - is rimless - but has been working just fine for 6 years and countless runs to 7k+ rpm.

As I recall, I bought the entire tensioner, but used only the pulley. As it turned out, the pulley wasn't the issue - it was the water pump after all.
