408 blueprint crate motor by Summit

I researched this motor and company for almost a year. I checked the BBB and they have many complainants. The motors are built by "Marshall Engines" After looking at many blogs and talking to people on ebay who had these motors, they all talked about problems with the motors as well as dealing with the company who back steps on the warranty; always blaming the customer/installer to get out of replacing among other things. I got a good deal on another motor, but I would save money and get an Indy motor. 375 or 430 HP motor and pick it up at a show while they run it for you right there. That was my plan originally in lieu of Blueprint.
