Hi there. If you are wanting to stay with the GM engines, then I say you can install any engine from the vehicles with 4 cylinders, 6-straight cylinders, V-6 cylinders and V-8 cylinders. All of the engines will fit into your vehicle as long as they are 540 cubic inch without modifying anything. Depending on what you are wanting to do with the vehicle. If you need further assistance with installing your engine, then seek out a professional, such as one from Your Mechanic, to help you.
