421 Stroker with Trick Flow Heads/Intake Dyno - Redux

Thank You for posting, it's helping to nudge my rudder in the right direction. I'm building a similar 408. Did you have any detonation on 92 octane with 11.0-1 compression? I was planning on 10.5-1, but if I can run 11.0-1, I'll do that. I appreciate you sharing this build with us. Paul.
