Which motor do I have?

[BobbyCTX]

Sorry it’s a 2004 not 2006

Any Mack gurus in here that can help me motor wise. 

I have a 2004 6 axle Mack that I inherited and I bought a new motor for it. The old motor both heads covers were stolenn off so I don’t know what hp or serial number on it. I hired a company that has since shut down by the IRS to replace the motor. Before hand they bought a new motor. Now I’m having issues with other mechanics saying it’s not the same motor and that water pump location are different. I contacted the companyc CA trucks that sold the motor and they say it will work. Other mechanics say it will but will be to much money to customized it. I was under the assumption it would be a drop in motor. Can anyone help me and tell me what motor I have in it just from the pictures? I know it’s crappy photos but it’s all I have. One from before they pulled it and several as it sits now. Is it worth it to continue to even pursue it or just sell everything? I’ve been trying for almost 9 months to find someone who will agree to work on the truck. Most deny bc they don’t like working behind another mechanic when the old motor was pulled. Some pics of old motor and new one are posted
