Let me start by saying that if I'm on the wrong forum point me in the right direction. I bought a Jeep with what I was told had a 5.0 HO from a 90 Mustang. A/C and Smog pump were removed. Waterpump is running reverse rotation. Is this right. I'm not sure that it's a HO.According to my temp gage its runing around 200 degrees.Is there a sure fire way to tell what engine it is?
