One of my regular readers, Bill, posted the following question in response to the piece I wrote on Chevy engines. Bill asked…
“No 454 V8 in 1971? I guess that motor came later. ..”
That get me to thinking so I did a little more research. The references I’m use are “Ultimate AmericanV-8 Engine Data Book” by Peter Sessler; “Standard catalog of American Cars” by John Gunnel and “110 years of the American Auto” by James Flammang and Auto Editors of Consumer Guide. I try not to get too much from the Internet at large.
Interestingly enough the 454 is briefly mentioned in the Ultimate American V-8 Engine Data Book, but there aren’t many details. That reference shows that the 454 was available in 1971 as a 4V producing 365 horse power. It doesn’t show under any model just as a general option for Chevy’s. I’m assuming it was just a 400 block with a different bore and stroke.
The 454 was developed by 1970. It’s bore was 4.251 in and had a 4 inch stroke (where as the 400 had 4.251 in bore and a 3.75 stroke). There were other version in 1970 and 1971, designated as the LS5. This version of the 454 was used in the 1970 and beyond in Corvette for one instance and was used in Chevelle.
Interesting that it isn’t referred to in the mentioned references for 1971 year.
Hold the presses!!!!!
It appears that in the reference “Standard catalog of American Cars” by John Gunnel that the 454 was left out off the comprehensive listing of engines for 1971. However, the 454 was use in the SS version of the Monte Carlo – 1,919 were produced. For the Chevelle 80,000 were sold with the SS badge of those only 19,992 were with the 454.
1917 Chevelle SS 454
1971 Monte Carlo SS 454
And in this reference I found the answer to a question I’ve had for some time. About 5 years agoing I was at a car show and ended up talking to a guy with a 1971 Nova SS. It had a 454 as the power plant between the shock towers. However there were 7,015 Nova SS packages sold, none had the 454 as the option.
If you read any of my pieces on Engines, you’ll know that I enjoy learning all I can about the various makers’ details on their features. I thought that I might start a series that took a year by year approach to what the US automaker build and used in the cars they produced.
So here is the engine line up for the 1971 Chevys.
Of course Chevy had the V8’s in 1971, not yet strangled by smog control, as well as 6 cylinders and 4 cylinders.
All of the 6’s were inline (often referred to as straight 6 – for the pistons all being in a straight line configuration) these were 250 cubic inch displacements – (very similar to the Ford 250, with the exception of the Blue upping the compression to 9.1:1 vs Chevy’s 8.5:1). These were cast iron with hp running about 145 with hydraulic lifter, and normally topped with a Rochester one barrel carb. Any car that had a 6 in it had this engine and it was an option with most any Chevy model.
1971 Chev Inline Six (this one is in a Chevy Nova)
Next up is the 4 cylinder used exclusively in the Vega (remember those?). They were inline 4’s with Over head Cams, aluminum block (not iron) and managed to displace 140 cubic inches. The compression ratio was less than they 6 at 8.0:1 with hydraulic lifters and a one barrel carb.
Vega Four Cylinder
There were 3 basic V8 that year the 350, 400 and the 307.
The 350 cid was cast iron with overhead valves and compression ratio of 8.5:1 with an hp of 245 hp when it was topped with a 2 barrel Rochester carb. These were widely used in the Biscayne, Bel Air, Impala, and Monte Carlo.
The 400 was cast iron as well with matching stats. However due to the larger bore (4.125 vs the 4.00 for the 350) and longer stroke (3.75 inches compare to the 350’s 3.48) it was able to push the hp’s up to 255 (umm..seems like a lot of work for 5 hps) when it was topped with the same 2 barrel carb.
The 307 rounds this out with its cast iron block and over head valves, it to had the compression ratio of 8.5:1 but with a smaller bore and shorter stroke (3.875 and 3.5 inch)it bu down roughly 200 hp. The 307 was used in Chevelle, Malibu, Nova and the Camaro.
Many, many 1978 Indianapolis 500 pace car replica Corvettes were mothballed with hopes of the cars turning into super collectibles, so finding a low-mileage example today isn’t hard. In fact, there are seven for sale in the December issue of Hemmings Motor News. One, formerly on display at the Corvette museum in Bowling Green, has just 116 miles on the clock. Another is advertised as having been driven just 700 miles. If you want a car you could actually drive, there’s a 1978 Indy Corvette with 22,900 miles.
Unfortunately, the demand predicted for these cars back in the Disco Age has yet to arrive. If you like ‘Vettes, you wouldn’t kick a 1978 pace car out of your garage, but as Corvettes go, these are considered lackluster performers and too many were built for them to ever be considered rare.
According to the Corvette Black Book, the original plan was to make 300 of the black and silver ‘Vettes. Mike Yager’s Corvette Bible claims 2,500. Had Chevrolet stuck to either of those figures, Indy Pace ‘Vettes would probably be more collectible today. But for Chevrolet, the profits these cars were raking in must’ve been as irresistible as coke at Studio 54. The Indy cars received a lot of hype, so demand went through the roof and Chevrolet cranked out 6,502 copies – more than one for each dealer.
With a base price of $13,653 compared to the standard Corvette base price of $9,446, the Pace Cars were expensive and profitable because they were loaded with “mandatory options.” Power windows, power locks, removable roof panels, rear window defogger, air conditioning, tilt/telescoping column, AM-FM radio with 8-track (or CB radio at extra cost) – all were included. Even this probably doesn’t help the value of these cars as luxury tends to be the exact opposite of what Corvette collectors crave today: radio delete, heater delete, oversized fuel tanks (when they were available), manual transmissions. You get the drift – racing-related stuff on a Corvette is hot. Stuff that you would normally associate with a Caprice Classic is not.
Anyway, receiving almost as much press as these cars received when new is a barn-find pace car offered for sale by Hemmings advertiser Corvette Mike. The car has been all over the Internet due to the fact that it has only 13 miles on the odometer. It’s even covered in an authentic layer of scurvy storage grime.
The pace car’s bonafides include a CB radio, Gymkhana suspension and the 220hp L82 350, all of which are cool. The fact that it’s an automatic makes it a little less so. Check it out for yourself over at Corvette Mike’s.
I had previously added a can of Techron Fuel System Cleaner. This was the first treated tank. Today the Vette need filling up and I recorded the incident.
In the second video please excuse the legs shot.
This first is the status as I pulled in to gas up.
I haven’t done much writing about my C6 Corvette, mainly because it has really been a great car (still is) even with the technology glitches.
However, as you might have gathered from the title there is an issue that I thought I’d jot down along with some possible causes and some preventive measures.
I recently had the problem with my gas gauge flopping round and kicking off the low fuel warning. Interesting enough it only happened immediately after filling up. It is an immediate reaction when I turn the car on. During this most recent incident the gauge remained flat-lined for what seemed a bit longer then it has in the past. I’m talking 20 miles or more with 3 stops full and shut down. It was accompanied by the engine light, which remained on after the gauge went back to normal and the low fuel warning stopped.
The Vette ran perfectly during the event so I’m not too worried , but still you don’t want to have to call the flatbed.
So I dropped a note on my corvette clubs site ACE (Arizona Corvette Enthusiasts) http://www.arizonacorvetteenthusiasts.net and to see what they thought.
Most swear by Chevron gas with its Techron cleaning agent and some were thinking it might be a sending unit and some said it is a common problem with C5 ( the previous generation of Corvettes).
Here are some comments:
—“Use some Seafoam (Autozone, Checker etc.) per directions on the bottle. Techron works also.” My NOTE: Seafoam is tough stuff, you have to be sure to change your fuel filter shortly there after.
—“Same thing would happen to me with Roxxane II (c5). It would show empty when I filled her up. I would use 2 bottles of Techron and then one bottle at every fill up for the next 4 tanks. Problem went away for a while. Then I would use one bottle every 2 tanks and that kept the demon away.”
This one was exteremly helpful……”Well, stop putting gas in it, maybe the problem goes away.”
—“It’s a level sender issue for sure. If Techron doesn’t solve it, you’ll either have to learn to live with it, or replace the faulty sensor. Do you have any way to check the codes to see which sensor is unhappy?” ( I don’t so if it acts up again, I’ll have to take it in.)
—“Two possibilities…. sulphur build up on the sending unit or the sending unit going out. I understand they are a biotch to change.”
—“My C5 had the problem unless I ran Chevron gas in it. About the second tank of non Chevron the gauge would go crazy. I would switch back and the problem went away.”
—“This was a common occurrence on the ‘early’ C5’s. It usually happened when high sulphur content fuel was put in. Some of the fixes were switching gas to adding a bottle of Techron every once in a while. The real ‘fix’ was a reflash at the dealer. Apparently the sender was a bit too sensitive, so they slowed it down.
I had the issue occasionally on my 99, but when I put a 2002 Z06 operating system into the computer, it went away.
Since you have a C6, I would expect that the issue isn’t a reflash. My guess would be that maybe you got some high sulphur content fuel or your sender is acting up in some way, maybe a poor or intermittent connection somewhere along the line.
—“You could try a treatment with Techron and see if that ‘cleans’ it up. ”
—“I was using the Techron trick in my C5. I switched to Gumout Regane Fuel System Cleaner. I t seems to help, although my gauge still jumps to E at times when below 1/3 of a tank. Good luck. It sucks to not really know how much fuel is in your tank. Although a Vette is light in comparison to other cars, I just can’t see myself pushing it into the gas station.”
So there you have a round of discussion on the topic.
Now the fuel leveling sensor is used because the C6 had two tanks and this keeps the tanks level. Which is important especially if you are running auto cross. Here is area a couple of graphics from http://www.corvetteactioncenter.com:
So you can see that it would a chore to replace. So I’m going to try the Techron and hope it works. I’ve been cautioned that I need the Fuel System Cleaner – not the injector cleaner. Here’s a pic:
Get the Fuel System Cleaner.
I’ve used my first 12 oz can and I’m currently at half a tank. I’ll fill it up again in a couple of days (Yes..when you normally drive it like you just stole it you tend to have to fill up – now and again..mostly..again!) and I’ll try to capture the event on my trusty Android.
Stay tuned (up). {someone please say they get that}
Folks seem to like this segment so let’s continue with 1950.
19 major car makers existed back then and Chevy topped the production totals with 1,498,590 units followed closely by Ford with 1, 208,912. The rest of the field were all less than have that.
So you’ve read my review and I promised to drop a note as to the “Long Lasting” part of Griot’s Garage’s – Long Lasting Tire Dressing.
Now is has rained nearly every day since I applied the dressing.
So take a look at the tires with 2 applications and 3 applications.
Tires with 2 applications of tire dressing
Here is the tire with 3 applications of tire dressing
Here is what I think as a wrap up. Long lasting to me doesn’t necessarily mean just duration, but can it stand up to everyday driving – oh—yeah…just in case I failed to mention, the Vette is my daily driver. It lived up to the Griot promise. I’ll continue using this product.
From time to time I check out a product that I hear about, in this case, from a repetitive mail from Griot’s garage. This is a catalog of sorts, with a lot of merchandise and everything you need to spruce up your ride.
Thier “Long Lasting Tire Dressing” is the first item I’ve tried.
If you recall I did a review a while back on a tire gel here is the link: ” Like and Don’t Like – Products (Tire Gel) and Tools (Thread Chasers)” http://wp.me/pKHNM-aJ
Now before we start, the bottle you see in the video has instructions and to be fair, I’ll give you any variations.
The direction say, roughly, clean the tire, apply with application pad and that a light application will give you a shine and subsequent will increase the luster. Not much there to go on.
Now you need to know that I applied the dressing with an old sock. Most manufactures always try to sell something extra and kt, which is an “applicator”, the magic potion and a terry cloth/micro fiber towel. I normally don’t go for that sales pitch. So that was the only deviation.
A couple more variables:
1. The dressing was stored in my garage. The temperature in there today was about 105 degrees. I applied the dressing while the car was in the garage.
2. The temp outside was about 108.
3. As you will see my Corvette’s tires have small sidewalls and a lot of small raised text and logo.
Ok so here are a couple before pics:
Before, notice the off-color
More of the discolor and you can see there isn't must sidewall.
OK after all these years, after the car was gone. I stopped by the house. I was met by Al, short for Albert, not Alan, as Al informed me.
I told him that I had always wanted to check on the Grande and he informed I was a bit late. He said he didn’t mind answers a few questions.
So I asked Al how got the car and he said he bought it back in 1972 from some guy. “It was a nice car with an automatic.” Of course my next question was what was under the hood and he said ‘nothing’. “Took it out about 10 years ago and parked on the side of the house.” He told me he never got the engine fixed, ” ’cause it ‘cost too much.” He ended up letting the guy that did some work on it keep. “Ya know, it might have been a 302.” He said he didn’t really know want to do with the body and just ended up hanging on to it.
So I asked him where the car end up, hoping it was sent out to be restored. He said there was this guy from Texas that would stop by every now and then and ask if it was for sale. He drives large pick up and always has an empty trailer attached. This same guy that has stopped by a co-worker of mine, who has her son’s 70 Monte Carlo and her daughter’s 1969 Camaro sitting under her car port – waiting for some TLC and try’s to convince her that she should sell them to him. She chases him off each time, but he’ll swing by a few months later.
A couple of weeks ago, Texas dude, stops by Al’s home and Al decided to get the Grande out of the yard and sold the man from Texas.
We talked a bit longer about my 1970 Mustang coupe and I showed him a couple of pics on my phone and then thanked him for his time.
