I think any 3.0 sohc 12v block will fit, with the fwd blocks needing a little massaging to fit, stuff like the oil filter is on the new dside engine mount pad, all pretty easy to fix if you are at all handy.

What exactly is wrong with yours? broke or worn out, and if broke, how bad and where?

If the block on yours is sound, especially if the block and rods and crank are ok or fixable, I think the best route is a local rebuild on your core. We KNOW how to do this on this board. Take a look at "Bob's 3.0 engine" by FrankR for a most exhaustive treatment of how to do it all the best way possible, a truly blueprinted engine. Way too good for Bob <img src="/forums/images/graemlins/evil.gif" alt="" /> <img src="/forums/images/graemlins/evil.gif" alt="" /> <img src="/forums/images/graemlins/evil.gif" alt="" />. You can build a sound, long lived engine for less than Frank did, but you must follow some of his steps to be safe. If you find a machine shop who will listen, you'll get a damn fine motor. These will do 300k with proper care, easy. FINE motors if you keep them cool and oil them well.
