Ok, keep in mind that I ran a 16+ in my less than stock Cougar, but here is my opinion anyhow. I think you will fall short of 13's maybe not by much. The general opinion on this site seems to be you can't do it with just bolt ons due to the heads limiting flow. You have improved the in flow and the out flow, but they may be outflowing your heads now, in theory.
Also, if you've never raced at the track before it will probably take a little while for you to get the 13's even if you car can do it.
What's that 4.10 gear like, do you have any idea what mph you are at redline in third? I'm curious because I've mostly seen 3.73's recommended for the auto's, but was wondering about lower ones.
My goal is to get into the 13's someday. I hope I get to see you try soon. I'll even race you maybe with all that power you will sit at the line spinning while I'm putt putting my way to another victory. lol
My official guess is 14.27@97.33mph. Depending on weather conditions this may be of by +or- .1sec or mph. lol
Gee I bet this helps you.
