It’s 1/4 mile.
Considering this is a FAST combo on repro bias ply tires, the 1/8 mile to 1/4 mile conversion for the 10.67 run lines up very closely(within about .01) with what would be a pretty well sorted out bracket car(1/8 mile was 6.793 on that pass).
You rarely see that out of a FAST combo.
Usually the 1/8 mile ET converts to a noticeably slower 1/4 mile ET than what the car actually runs.
Typically, the cars leave relatively soft, so the 1/8 mild times aren’t great, but they pull hard(the good running ones) on the back half.
