If you add 2 to the stroke of four inch bore small block Chevy's you get the cubic inch displacement:

302 stroke is 3.00 so adding 2 = 302
327 stroke is 3.25 so adding 2 = 327
350 stroke is 3.48 so adding 2 = 350

Camaro's where originally called Panthers, the first one sold for 2572$ and chevy did make 69 camaros in 1970 (the beginning of that year, the second gen cars where late)

Huh. Who knew......

While we are on the subject of Oldsmobiles, Olds had a 455 Hemi that was ready to be installed in 1971 442's. But unfortunately as we know 1971 was the end of the factory horsepower race because of emissions and insurance regulations. It would have been interesting...…..

My brother was involved with the Olds factory drag race program at the time and had inside info on this engine. If you look at the picture you can see the exhaust heat riser pipes and cast iron exhaust manifolds that indicate it was ready for production vehicles.

Correction, the 1963 turbocharged Spider had 150 hp.

Did not know that. Marketing definitely got involved in that name!

And the 67 Corvair Spyder had 180 hp

No, the fuel injected 283 was rated 283 horsepower, the dual quad motor was rated 270.

Yes the 283/283 was Rochester Fuel Injection.
2 Carter WCFB carbs with solid Duntov cam was 270 hp

They also sold a hydraulic cam 283 with fuel injection @ 250 HP and with 2x4's and a single 4....245hp and 220hp.

I started racing when they were everywhere....'57 Chevys and Corvettes...

That was not a good engine idea. A great looking little car( the Olds Jetfire) but numerous problems with the driveline....Usually wound up sitting under a tree....LOL

I don't really recall what the Corvair Turbo engine used but did not think it was the same as the Jetfire....To many years ago to recall. A buddy had one and it was pretty fast for a Corvair but it was the later year body style....maybe '65 or '66 ?

The Camaro was momentarily introduced to the public as the camoar. They had a 67 out on a stage with models holding individual signs, one letter per sign, and they all flipped them over to tell the world what this new car was called. A few of the models had gotten out of order...

I remember reading this in a ratty old book at a public library about 25 years ago, no reference to it on the inter web today.

The first automobile race was a few minutes after the 2nd automobile was built. (This is a great thread. I'm sorry I don't have anything of value to add LOL)

Liquid Tire Chains

In 1969, Chevrolet had an option for spraying liquid tire chains on the rear tires. It was activated from the driver's seat. Take care. Tom Worthington

Tom, that is the best one so far

I worked in a high end restoration shop for a short time in the mid 1970's...

The owner was a Packard Expert and wrote a well known book about Packards

I was amazed at some of the things that were on cars going back to the 1920's and 1930's that were in that shop.

Packards, Chords, Auburn Boat Tail Speedster, Cadillac....some cars I recall

Headlights that turned as the car did..Had 2 sets, 1 fixed set
Built in umbrellas and other things you'd never expect in the passenger area making for some real comfort
Front wheel drive on Chords
Supercharger
Electric actuated trans shifting
Overhead valves....
Pressurized oil systems but with copper lines instead of passages in the block...

Just some things I recall.....and I always thought old cars were very basic..

The Cadillac did have mechanical brakes and that was a mess of stuff that could go wrong...!

I don't know when "Juice" brakes came along but that was a big improvement....like replaceable bearing inserts....a very big improvement....

1978 Cadillac Seville
The first car to use a microprocessor was the 1978 Cadillac Seville. The chip, a modified 6802, drove the car's “Trip Computer,” a flashy dashboard bauble that displayed mileage and other trivia

Computers began being put in cars as early as the late 1970s/early 1980s. These would have been just sophisticated car control systems and originally only appeared in high end and performance vehicles. By the mid 1990s all cars had computers controlling sensors, combustion and interactions between electrical systems.

Somewhere in the shop I had a can of GM liquid tire chain

140 HP Corvair had 4 1 barrel Rochester carburetors, I had a 1965

The 1970 GTO had an option for Vacuum Operated Exhaust (VOE). The mufflers were made with a switch that would bypass a portion of the muffler to improve performance. Check out the article (https://www.hagerty.com/articles-videos/articles/2017/07/20/the-humbler).

It certainly was a great time for cars with factories providing these types of unique options for cars. Perhaps someone reading this thread had a GTO with this option?

In 1967 there was a "Turnpike Crusier" option for the Cutlass Supreme. It had a TH400 trans, a 2.56 rear, electronic ignition and the same 400 cu in engine as the 442 but with a 2bbl carburetor.
