Backfire? The motor is not even a year old - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The motor made a pop like sound and there was a grayish black smoke that came into the cab. I have not rawhided it none. I gave it HE77 going toward wilmington, I was passing everything on the road except near lake waccamaw, when I got towards a Citgo, an ABC store(Alcohol) I saw Blue lights and slowed Ol' Blue down. I was running 70 to 90 MPH, but mostly 75 to 80. So did this might have caused it to backfire I guess. What is Backfire, really never had any vehicle to backfire and my autotech class never covered it or mentioned. Is it over for my motor or do I need another motor?
Is my motor O.K.?

Please don't bash me cause I never had this to happen to me til now.
