Thanks for all the info guys.

Here is what's weird... I'm running on 87 octane and I hear zero pinging. Now, as you can see I'm no motor builder. I had a few gear heads help me out a few years ago and I'm just getting my truck put together and on the road. They estimated I would be running a pretty high compression. At least 9:1. Yet, I'm still running 87 octane fuel with no pinging so I guess I'm setup ok.
