hey guys, Im about to hit a 100k on my pony. I know the plugs and transmission fliud change along with oil is a must but wondering any additional things i need to do. she has o/r pype with custom tune and intake as well. looking on getting a throttle body and 3.73 gears as well. would the engine hold it the new parts and I dont race or redline at all. thanks for your inputs.
