Dan, what transmission are you running?Still iron heads, Edelbrock intake, and 50 year old afb carbs. And still 3850 pounds! 10.13! I am still stunned it went that fast! Backed it up with a 10.14. I think that’s it though. Air was good and I moved timing around and jetting and couldn’t get any more. Maybe there is a few hundredths but that’s it. I can finally say it’s maxed out.View attachment 86696
