422 dyno fail

Kent,
Thank you I have already decided to take the entire engine to the shop that did my heads. The shop who built the motor I would never say anything bad about I just do not believe he thinks there is anything wrong and the numbers are the numbers. I disagree based on what I believe this combo should make. I just feel there is something wrong. If the curve looked good with nothing jumping out at me and the numbers where what they are then so be it but I feel the erratic HP vs RPM curve is telling me something. Just have to figure out what it’s telling me. I would rather get the problem fixed now and save a catastrophic failure than throw it in. I’m trying to get my 72 and 71 dusters ready for the nationals. Not certain the 71 will make it unfortunately.

Jim
