Nice. I'll be running close to the same setup except a full SS 63.5MM headers-to-exhaust (Dinan Section 3). Excited to see how it performs before cams.

Looking for feedback on this run:

• Trace looks lumpy 4500-5500 vs other smooth traces here, but car seems to run fine.
• Power tapers off at 7000RPM

I always felt Kassel 'phoned it in' during the remote dyno tuning. I was renting dyno time and Kassel took a loooong time between runs to get back to the tuner because they were busy with other customers...which got.. expensive. Does this all look normal to you?
