David i do feel for you, and a lot of other racers out there that cannot check what they are getting back from the machine shop. I personally assembly every engine that i build, an i am amased at what the machine shops try to pass on to the customers. Now i know that most engines will perform well from the reputitably builders, but trust me you are not usuaslly getting what you were promised or what the tolerance were supposed to be. With todays compitition, a lot of the builders are just throwing them together, and hope they live a few passes, and then you own it, no warentee, (race Motor)
