What was the quickest car (completely stock) in 1969?

[Lynn]

Unless you can travel back in time, and conduct side by side comparisons with the same driver under the same conditions, I don't think there is any way to know.

By far the BIGGEST factor is driver. That explains why there may be a full one second difference from one test to another on virtually identical cars.

The other two huge factors are tires and track conditions (which include altitude relative to sea level, temp, humidity and of course the actual surface of the track).

I remember someone posting about the first completely stock car (an early 409 425 HP car) to break the 4 second barrier 0-60. I responded to the post saying there is no way it could do so on those bias ply 6 inch wide (tread) tires. The answer? They put some slicks on it for the test. Hardly a "completely stock" car at that point.

That roadtest was a ringer. Ronnie Sox was driving!

True, that. No telling what "sweetened up" meant.

Seems like hopping up the test cars happened often, but some big block manual transmission cars back then were low 13s and maybe a little quicker on stock tires.

My favorite article of all time:
"Some devilish product planners marched out a ZL1 Corvette equipped with 4.10:1 gears, an automatic transmission, and the key to the kingdom: 10.50x15 Racemasters. That thing ran 10.70s and bellowed all day long with idiots at the wheel".

I must have read this article 4-5 times in the past, it never gets old!

My office mate at MPG was there that day, at the Black Lake event.

Hard to verify the fastest stock car in 1969 or any other time for that matter. I look at trap speed as an indication of power to weight and is somewhat independent of starting line traction. Most small block cars of the muscle car era would not break 100 mph and even some big block cars could not do it. LS6 and Hemi cars were in the range of 103 to 105 mph and you heard of several that were close to 110 mph. These would be the fastest in my opinion. COPO Camaro's, L88 Corvettes, and other low production supercars would be in this range. Very few could exceed 110 mph without tuning or bolt on parts.

They listed the Buick Stage1 with a 455, that engine didn't come in a 69, it showed up in 1970 in the Buick.

I'm guessing power : weight wise, the Corvettes would have the edge.
