Ported 452 or Edelbrock RPM

Well, the dynamic seems a little high perhaps. What are the cam specs?
Good quench is at a max of IIRC, .050? I'm not remembering right now.
The worse the quench, the more prone to pinging it is.
I run .039 on my 360. I have run tighter, but it gets a little scary. Better than stock rods are a good move for tight clearances. There is less streching of the rod during higher rpm runs. Thus, keeping the piston away from the heads.
