I wasn't there...but let me remind you Dave...
YES.
This car with an OEM trans needs shifted out of third somewhere between 132 and 142 depending on the final gears. No super duper blower of any sort changes this.
It doesn't matter if it has a trilogy or not. Yours, mine, and the next door neighbor's all run similiar top end speeds. Although the relationship between the two is indeed intriguing to the masses.
What baffled me then, and still does now...how exactly did you (Dave) determine your top speed of 165? Was there a fellow at the track with a speed gun?
I'm not saying you didn't, I'm just wondering how you figured it? I did some tests myself but run out of road just above 140. Besides, the speedo stops there. With out equipment, it's ALL guess work from there.
