Has anyone here ever had an engine from Coast High Performance or ATK (sold on Summit)? I'm considering them because they seem to have everything I want in a shortblock and have a delivery time that fits my schedule. Both are listed having fully forged internals and I would have it in a few weeks. I would like to have the motor in and running by beginning of May. I'm going to visit a couple shops within the next few days to see if they can have a shortblock built for me in that time frame.

I guess I'm mostly asking if I would be getting a quality engine, or if I should avoid them.
