Need small engine in 3d model for Solidworks!

Hi! I have tried unsucessfully to find a model of a small engine. I have tried some of the recommended webistes suggested by our forums but nothing comes of it. Usually they are made in 3ds max or other graphics programs. There are sites that will sell them for \$200.00 and up but I don't want to spend that kind of money. It doesn't have to be fancy. I am working on a small portable sesimic rig using as Isuzu Diesel Engine. The whole thing is approx 24" square. Anyone have any ideas. I really don't want to have to spend the time to design this thing. Even a stp or iges file would be fine. I am using Sworks 2013 Pro.

Any ideas anyone!

Thanks

Paul
