How fast was a Motion Camaro

[GMH454]

Interesting to think about. Not talking about acceleration or time through the traps, but top end.
My car is a Holden Statesman special order, that ran local A/MP in 74/75. Car ran 454 13/1 alloy 074 heads 454 +60thou, muncie wide ratio and 12 bolt with nearly every known gear set known to man. What was unusual was it had a Hone O/D and was driven to and from the track even with the twin 4 barrels Grump lump and wheels sticking out 2" from the guards.

The builder who is restoring the driveline for me, Jim Rowley who is still racing nationally today, told me he topped out on the city highways at 7200 one night running a Mad Max (Falcon Cleveland Coupe that ran B/MP). Jim being a curious guy went home measured tyre dimensions gears overdrive factor etc., and concluded it was 172mph, which explained why when the road ended, he could'nt pull up and went through the intersection with horn blairing etc.

Drive line is similar to a Phase III Camaro, wonder what they did ???

On very slippery Sydney tracks, we never raced enough to get any rubber laid down, it went 11.68 and on a different run 132mph. Car weighed around 3,700 in racing trim. Car is documented by articles and over 11 mag appearances, so definitley not wishful thinking
