I hope you can view this article. Has some great cars – although the saying “keep the shiny side up” doesn’t really translate – these just don’t have one.
I’d love to spend time wandering around Cuba, just to look at the cars.
Well, I’m officially depressed. No it’s not because of the holidays, or the rapidly approaching June when I’ll move too far into the 50’s to be able to fool myself that I’m just barely 50, nope none of those things.
I’m looking at GM’s (bastards!!) Performance Catalog and all the shiny things in it. Like the ported LS3 heads, and the LS376 – 525…yes 525 hp in a crate engine, drop in and drive. I realize two things, I need an older Chevy to play with (or upgrade the C6 Vette) and that I’ll need a second job if I even want to touch any of this stuff and where will I live when the better half finds this stuff laying around the garage? (Tell me you aren’t depressed now?!?!!…It’s ok…admin it!!!)
Note: It’s gonna get worse… I have the Ford performance parts catalog as well…all I can say is thank GOD!!! I don’t have a Morpar to drive around….oh….the therapy…bills….!!! Why, OH Why didn’t I drink the family KoolAide when I was a kid..I would have been able to shun the Fords and Mopars and just be a normal one brand car guy??
There is some awesome stuff the Chevrolet Performance Team is put out, everything from small block crates to LSX monsters, to circle track crate engines.
Over the next few post I’m going to cover a few highlights and a couple unexpected – like engines for the Chevy Cobalt and some V6 engines. (Have just read some specs for the upcoming 2013 Mustang V6 – I want to see what Chevy’s got.)
In fact let’s start with something off the wall. Like the 900 V6 Intake for a 4 barrel carb!! What???!!!! It’s an aluminum high-performance for the 3.8 or 4.3 liter V6. So go ahead bolt on that 390 cfm carb..oh heck….grab that 600 cfm 4150 and drop it on top.
That is not a bad price. Of course it’s not for all heads, like it won’t fit the 3800 V6 or the 18 degree heads and you might have add a bump to your hood for clearance!!!
The world’s most significant all-Corvette show is moving back to central Illinois. After nearly a decade of being held at the Pheasant Run Resort in St. Charles, Bloomington Gold will be moving about 115 miles south to the town of Champaign for 2013, near where it first began nearly four decades ago.
According to Bloomington Gold CEO, David Burroughs, “Although it will be hard to beat the beautiful fairways of Pheasant Run, input from Corvette-owning customers wanted more opportunity for socializing and driving events as part of the entire Corvette show experience. It needed to become more dynamic.”
David went on to say: “Our customers own Corvettes because they are fun to drive. So, we needed a venue that not only served our exhibitors and customers who buy/sell and certify Corvettes, but also a venue that makes it easy and fun to navigate to/from and around the community before, during, and after the show. Therefore, we needed a small-town atmosphere with big-town hotels, great facilities, and quick escape routes to miles of country roads. Champaign, Illinois, has the smaller-town atmosphere, and the University of Illinois Assembly Hall grounds have everything else.”
So mark your calendar for June 27-30, 2013. Not only will this be the first year for the new venue, but it will also be the show’s 40th anniversary. And if you’ve ever attended one of the Bloomington Gold shows, you’ll know that there’s something very special planned that every Corvette enthusiast will not want to miss. In the meantime, the 2012 edition of Bloomington Gold will remain in St. Charles and take place June 21-24. For more information, visit BloomingtonGold.com.
I just recently picked up a copy of GMs new Performance catalog and all I can say is WOW!! But we’ll dive into that in a future post.
Gracing the cover was the latest and greatest COPO Camaro. You remember those special order packages. Well they have brought it back and factory racing just jumped up and shouted “LET DO IT!!!!” [vodpod id=Video.15839761&w=425&h=350&fv=%26rel%3D0%26border%3D0%26]
People love to talk about car sounds. We even mimic them. They can bring back memories of a car you or a family member owned. They can refresh visual memories of a race you attended or even participated in. They also bring back memories of a not so nice incident.
I can recall each sound in separate wave lengths in my first car accident, I was actually on my way to take my drivers test. I was driving my father’s brand new Ford Granada (he worked at a Ford dealership as body shop manager). The car was totaled, the other driver ticketed. A quick car swap and I went on to pass my test.
There are a few more sounds I remember. I remember my high school buddy’s 1973 Mach I, normally as he dusted me in my ’66 Chevy Impala an awesome noise that Mustang made. There was there the sound of the V8 under the hood of my Chevy – smooth but still throaty. (I don’t know if that’s even a work..but I’ll hustle over to Wikipedia and add it.)
But the other day was watching one of the Jason Borne movies and of course the there are the normal car chases. He was driving a little mini cooper and within all the metal crunching and tire squealing, there was one sound, at pause in the chase when he shifted that Mini and the sound the transmission made, triggered a memory.
In 1982 I was stationed in Germany and when I eventual got my European drivers license, the first car I could afford was a 1970 European Ford Escort. It was a 3 speed manual, shift on the flour and the sound of the transmission shifting in Jason’s Mini Cooper brought back that memory of my first European car.
My First European Car
Of course it didn’t have the pep that the Borne Cooper had, but it got me around.
Post up a note about a car sound that sparks a memory for you. Best one wins a free gift.
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.
