[M & M]

When the builder is done doing his thing, why not go to where he is and have him dyno the thing with you there? I realize this is going to cost some time and money but if it is not right when you get it back it will cost you a lot more. Especially when you consider the time to install and pull the engine again, send it back, agrue, yada, yada, yada.... you get the picture.

Good Luck,
Mike
