Displacement doesn't translate to horsepower. You gave us no idea what the original engine is (gas, diesel, marine, highway, off-road, etc), you gave us no information about the application, and you gave us no idea whether you were looking for matching specs or to upgrade.

To replace the motor mounts on a 1990 GMC S15 4x4, first, ensure the vehicle is safely elevated and supported. Disconnect the battery, then remove any components obstructing access to the mounts, such as the air intake or exhaust parts. Use a jack to support the engine, then unbolt the old motor mounts from the engine and frame. Install the new mounts by reversing the removal process, ensuring everything is tightened to the manufacturer's specifications before lowering the vehicle and reconnecting any disconnected components.

The stock jet size for the Predator 90 engine is typically around a 90 main jet. However, jet sizes can vary based on altitude, temperature, and specific tuning needs. It's advisable to consult the engine's manual or a knowledgeable source for specific recommendations tailored to your setup.
To remove/replace the engine on a mid-90's G series van, you must remove everything in front of the engine, from grill to radiator, and remove it from the front. You may need to remove the motor mount to crossmember bolts to allow the engine to move forward. It is best to keep the transmission bolted to the engine, as it will be easier to align, etc when you are ready to reinstall it. Keep in mind all the lines and wires will need to be disconnected, too. Get a Chilton bok and use it for reference.
