Question about gearing for Top Speed

I will say that going over 130 and an a body is terrifying! Emphasis on aerodynamics. I was doing about 130 in my dart and went from the center of the road to one lane in a swooping motion by no means quick, air got underneath the front and well my life flash before my eyes I could feel my car leaving the runway I managed to getback into my lane and thank God I'm still on this planet.

I looked down to change the radio at 160 and had shifted lanes in a blink.
new bushings and a tight front end was quintessential to safety, my friend with a 70's charger said his would lift up at 140mph-aerodynamics and that giant air scoop being all the physics stopping him at 140. Not the same with my plymouth though i was very excited
