Evo is short for Evolution Performance Driving School. Evolution Performance Driving Schools are hands-on, foot to the floor autocross driving schools. With programs designed to improve the driving skills of 16 year old novices to multi-time Solo II National Champions. (I didn’t write that it from their web site.)
This even is sponsored by the SCCA Tucson, Arizona Border region and will be held at the Marana Airport, Marana, AZ .
This weekend two instructors Brian Peters and Tom Kotzian will we taking us through our paces with our cars. Both of these guys have plenty of experience with National level Solo with the SCCA, including multiple National level wins, and Championships.
Yes I’ll have my 07 Corvette there and Well see how I do.
While I getting my act together after a very nice week-long road trip I wanted to share a car that I once owed and that for all too common reasons let it go to a new home.
1974 was about the time the U.S. government’s fossil fuel consciousness began to kick in, choking the horsepower out of the muscle car. But this car was an exception. Here’s its specs.
Gran Torino Sport
VIN: 4H38Q107971
Body: 65R
Color: 3D
Trim: DB
Trans: U
Axle: 9
DBO: 75
Date: 08/73
Vin Code: 1974
VinCode Body Serial = Gran Torino Sport 2dr HardTop
VinCode Body: Medium Blue Metallic
Seat: Balmora B/Cloth & Corith (L/B Bench)
Trim Code: Med. Blue
AxleCode = 3.25:1
DSOCode: Phoenix
Assembly Plant: Lorrian
Undercarriage is aerodynamic ball joints are much larger than other Torino’s of the same vintage
Transmission is unique (Minus the traditional “Humped” housing)
Engine is 351-V4 Cobra Jet (Not a Cleveland)
9” rear end
10.5:1 ratio
Came with a 3500 Stall Speed Torque Converter.
This was an amazing car.
Unless you are an expert on the Torino what you won’t know is that the 351 V4 Cobra Jet for 1974 was only one of 300 engines made that year. It took me nearly two years of research to find this out.
I sold this car to a nice guy up in Green Bay. Here is a before shot:
People love their cars. Some people love only a specific make or model. I case you haven’t noticed I have a thing for Corvettes and thing for Mustangs (yup Ford and Chevy). I enjoyed this comment from a guy who left it on my Facebook
Andy from my Facebook wrote this:
Part of the reasons why I Love Corvettes, the heritage, history and traditions. To some it’ ll be just be a car, to others it’ s part of their lives. A true Corvette owner/enthusiast will appreciate all aspects of the Corvette, from whateve…r generation. They may have a least favorite but none should be hated or looked down on, because without the last there would be no present. I Love the great community behind this Car, it makes owning one so much better. Owners all across the world willing to give others a helping hand, worldwide Corvette events are held, some over 500 owners attending, a lot for good causes. To me, that’ s something very special because this doesn’t just represent a “Car”. It represents a special select group of individuals willing to enhance the past traditions, that is Loyalty!!. I plan to hold onto it for as long as I live. Something this special is hard to come by and shouldn’t be let go. Just felt like sharing this thought!! Have a great Sunday.See More
Brent worte: Beautiful and well written Andy!
Tim Sweet – As a previous owner of a C4 and the new owner of a C6. You are right on Andy. Save the Wave!!!!
Yes I’m playing catch up with these. I’ll have another engine series coming up. Enjoy.

But in its place is the 400 hp LS2 powered 2007 Corvette.
She has a 6 speed manual trans mission, Z51 suspension, leather and power everything, key-less entry and starting and a host of other cool stuff. I’ll go into more detail in the next post.
I thought I’d miss the ’84 more then I do, it will be going to a good home and hopefully will stay a Crossfire. The ’84 goes with twice as many miles on it then when I bought it, lots of new, original parts and some improved and a really awesome stereo, it’s a better car then when I got. It deserves to be a show car and not a daily driver/grocery getter/race car (drags and auto cross)/show car. But it did them all very well, with the trophies to prove it. It was a lot of fun and I learned a lot about that middle ground technology that was a huge advance from the older cars, a first of its kind in many ways and a stepping stone to technology that is in the replacement Vette.
I’ve heard from a lot of guys (pssstt…when I use the word “guys” I mean all genders….just wanted to be clear ) that really miss driving their older Vettes, there’s really nothing that can capture the rawness of that kind of driving. I’m bit luckier then those guys because I can still jump in to my ’70 Mustang (thanks to a very understanding better half) and get that feeling of old school nothing but metal and tires driving. I think that alone makes it easier to let the ’84 go.
Thanks to the guys up at Dynamic Crossfire Solutions in Chandler, Az (http://www.crossfireinjection.net/) and all the guys in my Corvette club – Arizona Corvette Enthusiasts (ACE) http://arizonavette.net/, they helped a ton with my learning curve…HEY GUESS WHAT GUYS….I’m going to have a bunch of new ‘stuff’ to learn.
So get ready loyal readers, (all three of you!!!!). I’m going to take my average skills, average tools, and now below average budget and take on new technology.
Well, I’ve been preoccupied over the past week with …ok…don’t shoot me, you classic car lovers…….working a trade for a 2007 Corvette with my 84 Corvette. Yeah, I know..WTH???
I know, I know. I love my 84, it’s unique and the value has increased since I’ve purchased it. But there is a desire to upgrade. This isn’t the first time I’ve considered getting another Vette, I actually considered a trade for my Mustang for a second Corvette.
I have to admit the recent troubles with my 84 does play a small part of the desire to replace it. And this 2007 Black on black C6 with 4oo plus hp, with a 6 six speed manual trans, with only 40k miles. Still under factory warranty. But the price was just unbelievable. The original deal fell through because we couldn’t agree on a good price for my Vette. But it looks like I might have a second shot at it tomorrow.
Even if, it’s hard to get rid of my first Vette and there is always the concern that you’ll regret it later. So I figured, I just add a third car to my stable!!!!!…..oh….that’s funnier then you might think….considering how UNDERSTANDING my wife has been with my current stable of classics….but even I know that’s way…yea…way too much for even a saint such that she is. “Love you cutie” (just in case she gets really bored and actually decides to read my dribble.)
So I’ll catch you all up by the end of the weekend.
Oh..here’s what we are looking at. Drop me a note and let me know what you would do!!!
2007 Vette Trade or not too Trade????
Another view...give you view....trade or not to trade???
I have a fun give way coming up as well as some more auto factoids and a quick fix for my Mustang.
As you know the electrical system failure was the alternator and it was replaced.
A now the story continues……
I picked the car up and it started fine, even had power to flip the lights up (it could do that when I dropped it off) and I drive two miles home. It ran just horrible. No power at all. That was worrisome.
Now the ’84 Vette has a very simplistic computer that controls the fuel injectors and it does take a bit after a “power outage” for it to get the mixture correct. This should happen after a couple of miles. Well by the time I got home there was no change in the how utterly horrible it ran. So I took it for another spin and still no change.
So I disconnect the battery for a few minutes and then tried it again…still the Vette could barely keep idle and giving it gas made it shake and the idle dropped to 400, 500 rpm. So I thought ..ok..I’ll drive it to work in the morning and see if the 10 + miles will straighten it.
Next morning, a Volkswagen bus filled with 40 people could have passed me like I was up on blocks!!!!
Ok…at this point I’m getting a little bit…P.O.’ed…(that’s short for…oh..you know what it’s short for!!) I call up my guys and I explain my displeasure. My take was that they should have test driven the car and that they have had the damn (that’s short for @#$@#%%!!!!!) thing enough to know that it wasn’t running right. I expanded on my thoughts in person when I limped the car back there after work..which was not a great day…which might have contributed to my disposition. Sorry Sean, but you ya know noting but love…its all good dude….Sean later told me I hurt the only “feeling” he had…I told him to get over it. They had a new guy there and he was the one that test drove it after the electrical work.
This was the start of a 3 day, all hands on deck, WTH…(that’s short for “What The Heck” >wink?<…I didn’t want to push the envelope with the “bad words”, because I would have had to add “put the kids to bed ..I’m about to use some adult verbiage”) is wrong with this car!!!
I’m thinking it’s still electrical, computer was F ‘ed (short for “fried”) or there was a short somewhere. I ended up at the garage a couple of nights after work poking around a bit – Tim Sisk the guy that runs the places is good about that.
So here is what was happened.
It appears that the evap system that is supposed to take the fumes from the gas tank for emissions was filling up with fuel every now and then. This system is supposed to push the fumes through a canister filled with charcoal and remove some of the harmful particles. Of course it doesn’t stop there the “cleaner” fumes then are pass back into the intake manifold to be “re-burned” and sent out in the world through the Vettes exhaust system. This simple hose highway runs along the entire length of the car and isn’t designed to handle fuel.
The end result was fuel running through the hose design for only fumes, traveled the hose highway all the way to the front of the car, filling the charcoal canister – which wasn’t designed to hold gasoline. Once full the gas has not where to go but across the engine, just following Avenue Hose, and dumping fuel directly in to the intake. That’s the cause of the poor (understatement) idling and running. The car was drowning in fuel.
Canister - now rendered useless.
How does this happen? Well it occurs when too much pressure builds up in the fuel tank. The venting of the fumes is supposed to prevent that. Once the pressure builds, which doesn’t take long with a full fuel tank, the gas has to go somewhere, so it takes a trip up the evap hose.
Now, here is where a guy starts to wonder WTH (short for….) am I doing with a one off car???!!! Really the 84 Vette is a one off production year. There were not ’83 Corvettes sold and although it has the same basic engine as the ’82 Covertte crossfires, nothing else was the same, and the ’85 Vette was an entirely different animal. This leads to a fairly significant lack of printed knowledge on the system..this many years out. Why do I mention this? Because it’s tough to find the knowledge after this long and the newer repair books treat the ’84 systems as ..”oh yeah..it’s not the same as the ’85 or the “L83 (my engine) is similar.” Gee..thanks for that. But it is different and it’s not similar in many ways.
Here is one.
The fuel tank on ’85 Vette has what is called a check valve with allows vapor to travel through it, but if fluid enters it, a small ball is pushed by the denser liquid to a point where it will block the hole. There is a diagram of that in many of the new repair books. But there are none for the ’84, and no, upon actually view the parts, you aren’t going to see anything that looks like the ’85 check valve.
Ok..armed with is knowledge, I showed up at the garage and share the info. This left us all scratching our heads. There seemed not logical reason for pressure to build up. There is only the fuel pump down there (that we tested in a bucket of fuel and worked as it should) there was only one other fuel delivery system was the “limp home” system which use the oil sending unit to push just enough, when the tank was low or fuel pump failed, to get you home or a repair shop.
This lead into the third day, at which point the fuel module was removed from the tank again and it was discovered that there was indeed a check valve.
There is a check valve built-in to the fuel module, it had a piece something (appeared to be plastic or maybe rubber) lodged in it large enough to keep the ball in a position where the it increased the pressure so much that sent it shooting fuel out up the vacuum line. It was incorporated into the system in a way that was not conducive to separate replacement. It was cleaned and that solved the problem..well most of it.
The canister should be replaced find one it not easy. Right now we replaced the PVC valve with a right-angled and the canister is no longer in the flow.
For my 84 that’s not a problem since there is no sensor that checks that and the car is running great. I’m not sure but I think she’d even pass emission, unless they were to visually see that it wasn’t connected.
Of course I’m a big tree hugger and (you can tell because the Mustang gets 4 gallons to the mile ..hey that’s what dead dinosaurs are for!!!!) so I’ll eventual get it replaced. If I can find one. In the mean time I’ve re-routed the hose to protrude under neigth the engine so the fumes don’t fill the engine bay.
Some pics:
Hose Highway with Canister
End of the hose that is supposed to travel on to the Intake, now routed under the car, temporarily.
So there you have. Good thing there wasn’t a car crusher in towing distance….nah…I love that car.
