How fast was a Motion Camaro
 

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

Joel Rosen advertized that a '68 Phase III Camaro should do what, high 11's with a proficient driver? I think that's the ET he guaranteed. (Somebody help me out here.)

I think the Motion cars should do AT LEAST 11.50 with an experianced driver.

Guessing around 115 through the traps but on a straight road, no 1/4 mile how high would they run ???

Re: How fast was a Motion Camaro
 

There was a '78 Motion Trans AM at SR7, easily running in the high 12s with its original Motion Built engine.

Full option car with AC working and not sorted as previous owners had changed the rear end ratio from 4.10 to 3.55, installed smaller tube headers and a more restrictive full exhaust and dialed the carb in for ideling into shows.

Definately an 11.00 sec street machine when set up as Rosen Built it and not worrying about what may happen the original engine!

Heck I can't remember the times at SCR7 but remember Dan McMichael and the 71 Motion Camaro. That thing has so much power I felt bad for those poor tires. He was running slicks to. https://www.yenko.net/ubbthreads/imag...ns/worship.gif

Re: How fast was a Motion Camaro
 

I think GMH 454 is wondering what kind of top end mph you could get out of a Motion car. If it was set up with the overdrive it would be capable of some impressive mph figures!!!!

Intersting question due to the fact that these cars were built to go as fast as hell for only a quarter of a mile. How fast (top speed) has anyone here gone in their muscle car?

Re: How fast was a Motion Camaro
 

Truth be known, that was the first time I ever ran my Camaro on a drag strip. Even with a really screwed up carb, there was so much torque that I never did get it to hook-up. It just spun the tires (that was shifting at 5500 too!). Awesome feeling of power though...there is nothing like the sensation of big block. I can only imagine if it had just been tuned by Joel!

With my new 350 (upgrade from 305), I've buried the speedo (130), and let off. I still had gas pedal left, and I have no idea what the rpm's were running (no tach). I probably could've gotten at least another 10-15 Mph. All of this thanks to 2.73 gears; at least they're good for top speed.

There'll be no more of that, cause I'm gettin some 3.73's very shortly.

Re: How fast was a Motion Camaro
 

Okay, I dug up an original ad for the '68 Phase III Camaro. (See attached.) Joel Rosen guaranteed that the car would "run 120 mph in 11.50 seconds or better."

I cropped the ad so the performance claims can be read.
