and the best way to keep from having fire wall / dizzy problems , is to make your on mounts. Ive done this on 3 s10 builds. I actually just wellded a plate of heavy steel , not sure of the exact size to the factory mounts. It puts the engine close to the radiator , but not so close you cant get the belts off. You just have to use a pusher fan in front of the radiator. This will give you about 3 inches to the fire wall. Depending on what tranny you use , you might have to extend the drive shaft , wich I also do myself.
