It was about 4 years ago my friend and a couple buddy's bought a Chevy blueprint engine from summit and installed it then fired it up and coolant was coming out the tail pipe and radiator. Pulled the motor back out and took it back to summit where it sat for a while, he kept calling about it and they said to come and get it they put it back in and the same thing so they pressure tested it and one cyl wouldn't even hold 40lbs, my friend bought it on his A-Tech account so it is a first hand account. Summit wouldn't refund the money because they said there was nothing wrong, then the guy that owned the car posted a video on youtube of the coolant coming out everywhere and badmouthing Summit then summit stepped up and paid the bill for the engine. That's when my friend closed his A-tech account and hasn't bought anything from Summit Racing sense. I don't know who was all involved with this if anyone maybe some joker at summit who knows, maybe blueprint never seen the engine but the people that are selling your products should be taking care of your customers. All these guys are from N.E. Ohio.
