That certainly is a disappointing post from A bodies. I had my small block stroker built in 2014 and all the feedback I got then was good but obviously there was a change after that. As I mentioned they were not good at communicating but came through in every other way including engine dyno sheet and one stout engine. From their website it appears they are building complete assemblies
