1953 New Buick V8 Announcement

The Society is responsible for much of the content you see in this
e-magazine - like this 1953 Buick"Nailhead announcement.

Olds W-43 4-Valve

Understand you can't stick 4 valves in a Hemi head -
so Olds used a "pent roof" design as in Ford's 1964-1977 Indy
engine and their current "Coyote" 5.0 L Modular V8.

W-43 Head Shown

The Olds design is clean and compact.
No Hemi Chamber here - just a race-proven pent roof.

W-43 Head Shown

Olds managed to cram 4-Valves and pushrods, rockers, etc in a very compact design - there's a lot going on here - but it works!

W-43 in A-body Chassis

Automotive History Preservation Society Selects Wild About Cars to manage the Auto History Digital Documents Library!

The Automotive History Preservation Society (AHPS) a Michigan-based not-for-profit announced today that they have selected and entered into an exclusive agreement with Wild About Cars, LLC (www.WildAboutCars.com) to be the service provider, webmaster and marketing arm of the Society. In this role, Wild About Cars will be responsible for the maintenance and improvements to the AHPS website and will use its newsletter – No Limits – to publish AHPS generated content and market the Society to prospective members, material contributors and donors.

Eric White, President of the AHPS said, “The Directors and board of AHPS is composed of scholars, auto historians, researchers, and enthusiasts. Our primary mission is to locate and digitize the any and all historical documentation surrounding the American automobile. This includes factory and other documents, photographs, magazine articles, brochures and even auto advertisements."

"We are excited because Wild About Cars has the technical expertise and computer equipment to store these digital records in a web assessable library for our members and other historians to access and download."

"Through their 'No Limits' e-Magazine, we will publish the materials from our research along with reproducing actual materials from the period 1900 to the present."

Bob Gerometta, CEO of Wild About Cars said: "Wild About Cars has fully developed the AHPS web site for ease of navigation as well as for view and download the AHPS content. We are pleased to have been selected to serve the AHPS and believe that our No Limits e-Magazine will be an excellent medium for AHPS publication".

We'll keep you posted on the AHPS/WAC merger!

Today's Featured Article -
Don't Call Me a Hemi - 'cause I'm not! Oldsmobile's Infamous W-43

by Wild About Cars and AHPS Staff - reprint with permission only.

Wide valve covers don't necessarily mean a hemispherical combustion chamber - sometimes wide valve covers hide a whole lot of valves. Think 32 valves in an American V8 in 1971! It almost happened.

This is both a sad and an enervating story. It is a "what might have been" tale, but it is much more than that . . . it is a story about a huge engineering breakthrough in street muscle car head design, not so much because of its 4-valve heads (At the time, Ford Indy engines were running a similar setup) but because they were pushrod activated, and yet compact enough to fit in a standard GM A-body chassis. (Of course generating 525-550 HP on pump gas isn't a bad deal either).

This engine was to be the answer to the 426 Hemi, the LS6 Chevy and the SOHC 427 from Ford. They built this baby, but GM shut them down. Did they have the other guys covered? You bet they did. Read on to see how Olds did the impossible . . .

In the late 60's and early 70's, when cubic inches and horsepower ratings in excess of 400 ruled the day, the factories were always trying to wring more from their existing pieces. The practice was to get an efficient engine and then increase the displacement when more power and torque was needed. But engines still seemed to have a practical limit of about 500 cubic inches. By 1968 the factories had hit that wall, with all manufacturers settling at about 440-460 cubic inches as practical for a passenger car engine.

Most street pieces could reach about one horse per cubic inch with existing OHV setups and a good camshaft and carburetor(s). More horsepower was available, but it required radical camshaft timing and induction systems that were not truly compatible for street use. They made impressive HP, but they were not a car one could drive on a daily basis.

So what do you do after hotter cams and more carbs can't get any more tractable horsepower? Oldsmobile's response was valves - 4 of 'em. Olds engineers had been one of the first to install a flow bench at experimental engineering. Going back to the early 60s, they had studied airflow and combustion chamber configuration - way before anyone else was even thinking about it.

It is a little known fact that the reason why the stock Olds V8 engine survived so long in the GM lineup is because their combustion chamber was the only one that could meet emissions requirements without port fuel injection - hence all those carbureted 307s hanging on for as long as they did.

So it's no surprise that Olds engineers were looking for a way to get better breathing without the use of radical cams and huge ports (something that they knew would kill idle and smoothness) but yet result in good HP across the rpm band. The question was whether they could they build a set of heads that could be used with existing short block components and be manufactured in mass production. The result was what you see here, the W-43 high performance engine - slated for release in 1971- 1972.

Special thanks to Helen Early for these photos and to the members of Olds engineering for their input. I wrote this story for "Oldsmobile in Action" back in 1984, when this was still fresh in Oldsmobile staff's minds - otherwise, who knows all this might have been lost.

That's our argument for the Automotive History Preservation Society - too much is already lost or worse hidden from the world.

1934 Ford V8 Advertisements

By 1934 the Ford Flathead was well established, with over 250,000 already sold. In 1934 Ford wanted to make sure everyone knew that the V8 was smooth and easy to operate. Check out these ads - and notice that there was a strong pitch to get women driving this car -in fact, a woman is driving the car in all the ads!

1967 Dodge Hemi Charger Test
1967 Dodge Hemi Charger Road Test

Car Life Magazine had a chance to test the hot street Hemi in a 1967 Charger. They said: "Driving the Dodge Hemi Charger is like quarterbacking the Green Bay Packers" (Back then Green Bay dominated football). The Charger was no lightweight at 4560 lbs, yet flew through the quarter mile on skinny street tires at 14.16 @ 96 mph. Read about the head to head test between the 440-engined Charger tested by Road and Track and the Hemi Charger driven by Car Life in this test!

1946 Mercury Brochure
1946 Mercury Brochure

WW II was finally over and the auto manufacturers began to switch over from making tanks and planes to cars once more. But there had been not time to switch over from designing/building instruments of war to developing new cars. As a result, the factories cleaned up pre-war designs and started building once again. This 1946 Mercury Brochure gives you the flavor of where the industry was in 1946.

1989 Pontiac Trans Am Turbo Photos
Modern Muscle - 1989 Pontiac Firebird Turbo Trans Am PR Photos

The 1989 Pontiac Firebird Trans Am is significant in more than just the fact that it paced the Indy 500. What is even more interesting is that this is the one Firebird that had some serious moxie - from none other than Buick! The G-Body (Buick GN) was gone, but the F-body remained - s what better place to stick that fabulous V6 Turbo than in a car that would pace the 500!

Check Out Techipedia What is "Techipedia" and why do we do it?

We have lots of material in the AHPS Library, but sometimes it's contained in a host of materials or it comes from a combination of our sources and those on the outside. As such, it would be a big pain for you to gather all that up. So what we do is put it together in one or more articles in a single place. So take a journey through "Techipedia" - you'll be glad you did!
