Barracuda "426"

It's in the Hemi hospital for the weekend, I heard a noise that was not a happy sound on the right bank,but I believe he said 150/450 on the spring pressure. I'll doublecheck next week. Thanks for the tip on the bracing from USCartool. I wasn't aware of it. Maybe I'll ad one this winter. I'm am not an engine builder so I rely on Al to do my engines. Very professional dedicated Hemi guy......
Any new updates?
