i have a little 200 in my car but i was tired of not having any power so a uncle of mine gave me a 289 of his that him and his dad rebuilt. but the engine was too big for the car they had. so it sat covered with cloth and covered with tarp never been used. so me and my dad are planning to put the bigger engine in my car but i thought would i have to replace some bearings, fule pump, water pump. or would i even have to completely rebuild the whole engine again? please tell me everything i would have to to to get it running again.
