94 3.0 interference engine or not??

Please tell me if a 94 3.0 engine is or isn't an interference engine. I bought it used and don't know if the timing belt has ever been replaced. I'm just wondering if I'm rolling the dice by not replacing it. I don't mind paying for a tow job when it goes, but scrambling the valves is a different story. Thanks if advance..

Nope its not an interference engine, well, its not supposte be anyway, when carbon begins to build up it can be.
