Trick Flow small block heads

I heard a slight stumble off the line and could be a small piece of the 60" foot problem.
It was more of a delay, like the converter didn’t flash as high as it had in the previous combo (3500) but then it comes to life like it always has, but I can’t recall if it did it the other (first) run or what exact rpm’s it was at etc, my multitasking (along with focus and recall) needs some refreshing for sure
