Most, if not all of the noted chassis have a lesser chassis weight, lower CG, refined suspension geometry and much,
much more braking capability than your Olds.

Your Olds is in the same ball park for weight as the underlined Viper GTS. Yeah, you got it on acceleration, but deceleration goes to the Viper... so its a probable wash.
Thats is why I gave you the 12.5 second goal frame.

Maximum decleration on average, for a DOT street leagal tire is right about -1.3G. 100mph is 146.7 feet per second. 146.7fps at -1.3G... do the math. But what really needs to be paid attention to is the 150-0 numbers. That is what really tells you whats going on when looking at 100-0.
FWIW, I dont have the 67 completed. Nor have I completed a 0-100-0 test, at this standing.
But, a very similar chassis with the same components loaded ,
does an as tested 60-0 in 89 feet and is about 200lbs heavier than my own 67 which is @ 2800lbs. All I know is, that's faster than any production car ever constructed.
