I'd shot for an air fuel ratio of 13 to 1. the dyno is great for tuning

The only number that counts for me is the time after 1320 feet. I don't care if my rwhp on a dynojet says 500 hp but I do the 1/4 in 14 flat. BFD!!! But what I do know is that I cannot throw my hands up and say that where I am is as good as it is going to get. Otherwise, my 1/4 times will be disappointing. I have seen inferior builds make 25 rwhp more than mine. As for my torque numbers, I will take them! I just know that I should be getting more hp at the rear wheels.
What I do know is that I have plugs that are a touch too hot for 11:1 cr. I have autolites 3924s good up to 10.5:1) and I need autolite 3923s, one heat range colder for my CR. Also, the plugs have not yet been gapped. I understand that can make a difference.
