Southwest Engines Sold me a Bad engine and will not return my calls. Tulsa Oklahoma

I purchased a engine from this company. Upon doing thier "checklist" of stuff to do before installation, i noticed a water\oil mixture on top of cylinders number 1 & 4. I called and left several messages and sent e-mails with no response. The engine is still sitting on top of the original pallet it was shipped on. I am a mechanic and i know that a water\oil mixture is either a cracked head, block or cracked head gasket. I have a friend of mine who ownes a mechanic shop and ordered a motor through this same company and is currently going through a lawsuit with them. I have also found out that they claim to be a part of the BBB, which is a lie. I have numerous other complaints about the engine i've recived, but i don't feel like listing them all. I would be intersested in receiving a call from an attorney on starting a class action lawsuit on these scam artists. I don't know how the owner of this crap company can sleep at night knowing that he is ripping people off! I am available anytime and would like to be a part of Karma kicking their a*.
