Anyone dealt with Modern Muscle Extreme AKA Modern Muscle Performance

Hello Everybody,
Just a quick question. Has anyone dealt with Modern Muscle Extreme or are they still in business? The reason I ask is because I have tried to contact them a few times via e-mail and have not had a response. I am looking for a new 5.7 after my last one went kaboom. Living on the other side of the world makes it hard calling and I just need a few questions answered. Also if anyone has purchased engines from them how did it go? Thanks for your help.
Regards,
Ron
