What is your body style and how much does it weigh?. Looks good under the hood

ET, 60ft and all that is great, but mph is power and you are down some. Could be the weather, but you need to jet for mph and then work on the ET.

I agree and this is a different carb than what he ran before so no back to back test and the weather was apparently warmer than the 9.98 best. What fuel do you run and what compression Mikey?

110 sunoco and 12.5 compression.
Keep in mind i had dist issues so first run was 9:30 and three bad runs and last one was a good one for how hot it was.
My next TNT will be MATS in two weeks so trying to sort out anything i can before.

Only really got to see the last run and held from 12 to 13 after i shifted to second and high gear. My Buddie was able to turn the gopro off and on from his phone and download it but couldnt zoom in on it on the first few runs but was in the green digital lights the whole time. I need to mount it closer to the gauge to really read it.
Still it never ran that good in the heat so it was encouraging

There's more there for sure but good runs. In thr green is not enuff info so see what's needed to see the gauge and can you post plug pics?

As we spoke earlier jet up till it slows then we can tweek the high speeds if necessary.

Got my fuel filter today, installed it, put fuel in the cell,,fired right up!!! About 3-4 minutes of warming up, I could get out of car and check the timing, as I had the distributor out priming the new oil through the motor after oil change. I reset the timing to 35* as it was at 40* from my priming and replacing,etc. Let it warm up to 190* and adjusted idle RPM. Gave the idle air screws about 1/8 turn out and all was good. Sounds VERY clean and CRISP at idle and revs quickly. The Township went by today with their sweeper getting the cinders off the road, SO, I'm thinking they know I'm getting ready to roll here!! THANKS Dom!!

There is nothing to see mixture wise on that plug. The only thing the threads and strap tell you is heat. The mixture is read off the very base of the porcelain. Out there on the end means little to nothing
