Are you buying an engine with an 80? Not sure what the question is here. A 4l80e would be a good choice for this build depending on what you are going to do with this car. Feel free to give us a call next week if there is something we can do for you. Vince

It will depend on what the engine came out of. The silverado ss had a 4l65e in it. Depending on the condition of the unit you might be able to use it as is. Or have someone go through it to suit your needs. If there is something we can do for you let us know. Vince
