Happy July 4th! If you have speakers plugged into your computer, turn it up. Hopefully you have a subwoofer, too! This footage is me walking through Vic Edelbrock's collection of vintage Trans-Am racecars as they're being prepared for the Group 7A races and enjoying the sights and sounds...
The Trans-Am Series is an automobile racing series which was created in 1966 by Sports Car Club of America (SCCA). This was the proving ground for all American manufacturers to compete with race-modified production cars. It ran until 1972 when at the height of Richard Nixon's incompetence dealing with OPEC, we had a gas shortage which was compounded by an embargo levied against us. Syria, Egypt and Tunisia didn't really like Nixon re-feuling their arch-enemy, Israel. Rather than address the shortage, the auto industry was heavily regulated to curb consumption. Further restrictions placed on the oil industry by an other rocket surgeon, Jimmy Carter, left us unable to further develop our own oil supplies which cemented these changes to the auto industry. These events changed muscle cars as we knew them into complete turds for over a decade while US auto makers struggled with the regulations and re-learned how to produce decent cars again... but for the "pony cars", it was the beginning of the end. The oil embargo of 1973 changed the shape of not only the auto industry, but all forms of auto racing to follow.
You used to be able to afford these cars. I remember when... back when I was in high school...
But it's 2010 now. This race celebrates all the classic cars you've dreamed of owning or being seen in. These things auction in the 6+ figures now (because of their race history). Enjoy this parade of '60's and early '70's model Ford Mustangs, Chevrolet Camaros, Plymouth Barracudas, Mercury Cougars, AMC Javelins, Pontiac Firebirds, and Dodge Challengers. This event required that they be in their original race condition in order to run with the Group 7A cars, so the contest to follow is all about how much compression these 40+ year old cars have left, and who's driving it. These beauties have been meticulously preserved by the best collectors, engineers and mechanics in the industry. I hope you guys can appreciate it because this is off my normal subject material.
I just wanted to change things up and post something American on Independence day. This one's for the Veterans.
Trans-Am Group 7A Race at Laguna Seca
Pardon the shakes. I traveled 3200 miles to see this and I don't carry a
tripod on this trek. I've cut out some of the panning, but how often do
you get to see these kinds of cars actually racing the way they were
intended to be raced?
Enjoy the thoroughbreds!

The Cars of Mark Donohue
Some of the cars that Mark Donohue made famous. Included in the video are
several of his Trans Am Camaro's, his Championship Trans
Am Javelin, and the last car he ever won a race in, his IROC Porsche 911.
Filmed the Mark Donohue Reunion at Road America during the Kohler
International Challenge with Brian Redman, July 15, 2010.

Trans Am Depot's HURST TRANS AM at the 2012 SEMA Show
Very Rare. Very Well Done.
There are few names in the automotive world that are more respected, more
revered, more trusted than the legendary Hurst brand. There are few cars
that have prowled the streets with greater authority, more dominance and
commanding presence than the famous Trans Am. Not since 1997 have these two
iconic brands joined forces...until now.
1969 Penske Trans-Am Camaro
The 1969 Sunoco Camaro
championship winning car. Driven by Mark Donohue the entire 1969 Trans-Am
Season. It won six races and finished second in another two. The sister
car, driven by Ronnie Bucknum finished 3rd in the Championship, and was
later destroyed by an earthquake in Mexico.
Calculate Your Compression Ratio
This is everything you need to do to calculate your compression ratio. No
foolin'. Every equation and process demonstrated. Find all your
variables. Know your exact compression ratio in every cylinder. This is
how you do it.
Just because your service manual says your car is 7.8:1 or 8.5:1
compression doesn't mean that it is. Whenever there are casting
irregularities, variations in piston height, parts that have been machined,
non-OE parts, or changes to your head gasket selection, your compression
ratio WILL change. It's highly probable that you're only CLOSE to spec if
you've never touched your engine at all since it was "born", and that it
doesn't MATCH spec. Even if it did, how would you know? This.
V1 Swept Volume
V2 Deck Volume
V3 Piston-to-deck clearance
V4 Piston dish cc's
V5 Head combustion chamber cc's
The ratio math:
V1+V2+V3+V4+V5 = volume of combustion chamber at BDC
V2+V3+V4+V5 = volume of combustion chamber at TDC
The ratio is...
(V1+V2+V3+V4+V5) ÷ (V2+V3+V4+V5) : (V2+V3+V4+V5) ÷ (V2+V3+V4+V5)
BDC ÷ TDC : TDC ÷ TDC
First you fill in the variables, then you calculate volumes, then you add
the volumes, then you reduce the ratio (fraction). It's that easy.
Here are your magic numbers:
0.7854 = Pi quartered to the ten thousandth
16.387 = number of cc's in a cubic inch.
If you divide any number in cc's by 16.387 it gives you inches. If you
multiply any number in cubic inches by 16.387 it gives you cc's.
Quartering pi lets you use the calculation:
BORE x BORE x STROKE x .7854 = volume of a cylinder
π x (BORE ÷ 2) x (BORE ÷ 2) x STROKE = volume of a cylinder
Either way is right. You get the same result if you calculate pi to the
ten thousandth. While I apologize for all the math, no I don't. I'm
really not sorry. You actually clicked here for it whether you realize it
or not. This is ALL the math, the tests, and the whole process to
calculate your cylinder volumes and compression individually even if you
don't know any of your variables yet. All of my numbers are present for
those who want to calculate out the last 3 cylinders out of curiosity just
to see how it affects cylinder volumes and compression ratios from one
cylinder to the next. Why would I do that for you? Why would I deprive
you of that practice?
Just assume that all 4 of my combustion chambers are 41.75 ml if you do
Clicking like share and subscribe helps a channel grow. It also motivates
me. Don't sweat the camera. It's enough to know that so many of you care
about what I'm doing here. From the bottom of my atmospheric dump, I thank
you all! This gift horse's teeth are all over the place, but he sometimes
poops gold nuggets.
PS: Use ATF for your piston dish volume tests, not alcohol. Of course
it's better just to use the spec sheet included with your pistons... but
not everyone gets that luxury. Water is just fine for head combustion
chamber tests. Dry and re-oil all parts that water touches.

Here's a clip from the ultra-rare 1969 product intro film "The New World of
American Motors." This clip is from the original negative. The clip
features Javelins competing on the 1968 Trans-Am racing circuit.
Get the film for yourself on Torq-O's "The Late Sixties World of AMC" DVD

NASCAR of Yesteryears
Remember when you could recognize a NASCAR chassis? Back when they used
production cars? Be nice to these old ladies... They're packin'. Don't
let the drum brakes fool ya.
1969 AMX (SS/AMX) sounds tuff, at the Mopar Nationals, IN, 1997
We are at the Mopar Nationals in Indianapolis, IN. The AMC cars had an
invite to the show. Jeff Kennedy and myself volunteer our time to help out
with the parking as members of the AMO. A fine sounding SS AMX pulls into
park on the show field. There where only 53 of these cars built for racing
only. 8-1997. tHANKS FOR WATCHING
