You are correct. A good head wind plays havoc on pickup trucks. I'm sure it would go over 100+ mph, and I will say I believe it would have got into the 12's also, even if barely. Not sure on the other car
Yes, the head wind does kill. My full size, loaded (panels, AC, seating, front and rear) B300 Maxi Van runs a 16.0 @ 89 MPH in the 1/4. Not sure on the short time. 340, iron heads (X), with a little work done.
