Was it the WO/RO Hemi cars that got a crappy single exhaust wired up in anticipation of adding headers? I heard this rumor on both the WO/RO and Hurst/Hemi cars (possibly neither?), but I'm not up on my Mopar trivia like I need to be!

I found an ad from 1974 listing the Motion 9 sec Vega. This had to be one of the most outrageous cars ever offered for sale to the general public. It was not long after this ad appeared that the Feds came in to the Motion garage to look around.

Does anyone have an opinion regarding the 1970 Buick GS, 455 Stage 1? I have been told that this Buick was fastest muscle car produced [img]/ubbthreads/images/icons/smirk.gif[/img] . I have had numerous debates regarding this issue! [img]/ubbthreads/images/icons/grin.gif[/img]

Mike I forgot all about the buick GS stage 1 I think you are right you normally you do not think of a buick as a muscle car
As far as how it was right out of the box the 455 stage 1 was rated at 350 Hp @ 4600 but had a wopping 510 ft lbs of torque [img]/ubbthreads/images/icons/shocked.gif[/img] Buick had planed a stage II only a few were built before Gm cancelled them It was said that the stage II could run the Ü mile around 10.90 at 121 mph [img]/ubbthreads/images/icons/shocked.gif[/img] . I do not known if there are any of them around today ?? I would think that would be real rare [img]/ubbthreads/images/icons/smile.gif[/img]
Also lets not forget AMCs 1970 reble with a 390 @340hp with 430 ft lbs of torque

It is my undersatnding that only one ,or maybe two, Stages IIs were made. I don't know too much about them. A friend of mine has an article on the Stage IIs that he is going to give me and hopefully it will give me some good information on these cars.

Mike
All I can find right now is there was around 50 stage II heads built
Not to say how many engines were really built It would be
Real interesting to find out [img]/ubbthreads/images/icons/cool.gif[/img]

Found more info StageII was a over the counter package only No production cars built as a stageII The heart of the stage II was the cam 455 in 480 ex with 455 in and 480 ex duration An aluminum intake with a 850 cfm Holley on top The big thing was the heads
With redesigned ports good for an extra 50hp

Renoylds, At one time I owned Amc's Rebel "The Machine", The owners manual claimed 14 second quarter mile times, which the car would do. Lets also not forget the AMX with the GO PACK in 1969.
