Hello first time dodge owner. I've got the 94 ram 1500 3.9 by poor thing has 296xxx on the dial. I wanna pull the motor n swap because engine oil looks like chocolate milk. What years are compatible. Preferably block numbers x though block number x or put me on the right trail. Any tips n tricks are appreciated. I live I'm Or. What else can I do to big.red to give her that fire.
