1957 – 1958 saw the use of the New 283 engine in Chevy‘s including the Corvette.
The Corvette was fitted with the Rochester RamJet and RAM’s horn intake as the RPO Code 579D. But recently during some research I read that there was another modification.
It was called the Air Box Option, RPO 579E and it was perhaps the first production cold air induction system(at least for Chevy).
It consisted of a plenum box mounted on the fender well of the driver’s side. The box was fitted to an opening in the bulkhead next to the radiator with an air filter inside. The duck work ran to the fuelies injection unit.
Records indicate that there were only 43 produced in 1957.
Oh yes, believe it or not, the 283 put the Corvette at the cutting edge of performance in 1957, fitted with the RamJet FI (fuel injection) system (“fuelie” was the gearhead term for that). In 1958 the 283 was the base engine for the Corvette, but the 283 that use to put on 283 hp was tuned to create an even 290 hp. If that wasn’t enough for you (of course it wasn’t enough, two words that should never be heard together ‘enough’ and ‘horsepower’…unless…the word ‘not’ precedes them). The RamJet FI was an available option RPO 579D.
Additional configurations were dual four barrel carbs that produced 270 hp, they were either Rochester or Carter AFB. The cam was changed in 1958 to give 0.398 inches of lift, improvements made to get more oil to the lifters and the exhaust manifold was reworked, called the Ram Horn’s manifold. There was a change in how the 283 was mounted. Chevy used the 3 point system with a mount on each side and one at the rear of the engine at the transmission.

In 1961 the FI jumped the engines’ horsepower to 315. (Hey, the base corvette in 2007 was 400 hp.) The FI wasn’t the only improvement for the 283 in 1961. It was treated with a set of solid lifter, improved heads and hydraulic cam which helped the block rich 315 hp, easily. This would be as far as the 283 would go in horsepower – in production. 1961 was also the last time the dual four barrel carbs were available as an optional configuration.
By 1962 the 283 was replaces by an entirely new engine the 327 (that’s another mini series) as the premier Chevy small block. The 283 was dropped from the a power plant for the Corvette to a base engine for Chevy’s passenger and used from 1963 to 1964. Its horsepower dropped to 170 and 195 for two configurations. A small bright was a four barrel configuration for 1965-67 that produced 220 hp. (That was the configuration of my 1966 Impala convertible.)
Of note is the use of the 283 in Chevy’s light trucks with a two barrel configuration for most of the models in 1958 to 1962. It produced only 160 horsepower. For the 1963 to 1967 light truck models the hp was increased to 175.
So far my writings are about engines have been ones I owned and the 283 was the engine in my very first car. It was a 1966 Chevy Impala. It was a gift to me for my 1976 high school graduation. The car was restored by my father, who was a master auto body man. The car was a convertible with A/C and glass rear window. It sported an automatic Powerglide transmission.
The 283 was a simple engine and of course the engine bay of the ’66 Impala could hold a family of four, with lots of room to work in there. Oh…those were the days…a piece of cardboard on the ground and 3 bolts later you’d have the starter out. I wish I could find a picture, I know there were some taken, polaroids back then, but they’ve disappeared over the years, much like the car.
So what’s the history of the 283 and what was it used in. Well those answers are coming up as well as two special uses of the 283, one in the past and one modified restro-mod use…(yeah…someone mod’ed a 283..very cool, but that is later).
As with most engines the 283 wasn’t drawn up on the design boards and produced. It was a result of Chevrolet’s desire to increase performance of a power plant they already had on the shelf. The 265 cubic inch small block underwent transformation that resulted in a new engine in 1957.
The modifications made to the 265 to create the 283 were increased bore from 3.75” to 3.875″, the main bearing was given 2.30” journals and 2.00” connecting rods. The base configuration (with a two barrel carb) for the 265 produced 165 hp, the 283 made 185. Twenty more horsepower doesn’t seem much but toss on a 4 barrel and the 283 takes off at 220 hp which tops the 265 similarly configuration producing 185-195 hp.
Chevy's 283
1957 was a good year for Chevy. Bill “Grumpy Jenkings took a 283 fitted with a dual carb set up and achieved 270 hp. It was also the first year for Chevy’s Rochester Ram Jet and what better engine to use than the new 283. This combination took the 283 in to the history books by producing horsepower that equaled the displacement – 283 c.i.d. and 283 hp.
And that is what led to the installation of the 283 in Chevy sports car platform, the Corvette.
Unfortunately I have to start the year out with a legal notice. It seems that my writings are so inspiring(…ok…stop laughing!!!) that a few sites have decided that they would use them on their sites in total, placing ads in the middle for their profit and not requesting permission.
I enjoy writing my blog and I do it to share experiences and social interaction.
If you like it, great!!
If you’d like to share links, I’m all for it
If you want to post entire articles ask permission and I’ll send you my list of requirements for accomplishing this.
If you want to use my articles and place and in the articles, we need to talk first.
As we close out the year that was 2010, I celebrate the first year anniversary of Average Guy’s Car Restoration, Mods and Racing.
Over the past year, I’ve enjoyed jotting down my thoughts and experiences. Mostly, I’ve enjoyed hearing back from readers here on my Word Press main site and in other social media.
This past year I’ve seen the page views on this “one man” blog go from just a couple per week, to nearly 1500 a month. Not bad for a non-commercial blog, with no paid advertising. So THANK YOU. I hope to hear from and read your comments and views in 2011.
What’s coming up in 2011? Mods on the ’70 Mustang, tweaking of the LS2 on the 07 Corvette and I’ll continue with the Auto Factoids in their new format. You will see more mini engine series, kicking off the New Year one of my favorites Chevy’s 283 and there will be more racing events, test ‘n’ tunes and Mom and Pop racing teams highlighted. There will be more contests and DVDs to give away and project updates from readers. Oh…I’m coming out with the Average Guy’s 2011 Calendar look for that on-line.
It’s going to be a fun new year.
To you and yours – may 2011 bringing nothing but happiness and joy.
O.K., I don’t do this too often on this blog but every now and then I have to point out something I think is just ridiculous.
I do a lot of reading. A disproportional amount of that reading is car magazines. (To my son: Yes I will get to the two Stephen King novels you bought me…promise!!) In fact, I get so many car magazines that it’s difficult to keep up (sounds like a New Year’s resolution is in order). They stack up and my wife’s patience goes the opposite direction with my messy side of our shared office and piles here and there of unread periodicals. (O.K. so that New Year’s resolution may turn in to a ‘CLEAN IT UP’ New Year’s directive, in which case, failure to comply would not be an option.)
In the course of all this reading I’ve become familiar with a lot of writers and their styles (some I communicate with via email or social network). You also gain a general over all tone of their respective magazines. With the exception of my favorite writers at the mega car publication company (SHOUT OUT TO) Hemmings (I refer to them as “They Who Do No Wrong”) who seem to be pretty down to earth and hug the middle line pretty well, it’s clear that some car magazines want to project a blue-collar image and others a blue blood image. Every now and then, the blue-collar want-to-be’s do grab a seat on the snob express and leave us average guys going.”..W..T..H(family blog)!?!?!?!…..REALLY!?!?!?!”
My inner lawyer cautions me to not use names of magazines and writers, of course suing me would pretty uneventful, you might end up with a 70 Mustang coupe and a 302 and that’s about it. My inner writer says “If you ever want to move your writing anywhere other than on this blog, do not insult the established press.” My inner wise-ass (still family safe, I believe) wants to poke fun by name at both (magazine and writer). Normally my inner wise-ass wins.
So I am reading the latest Car Craft, Jan 2011 (yeah, it some how ended up on top of the pile) which I considered a blue-collar magazine, lots of get dirty articles and useful techie stuff and not just shiny pages, shiny paint and expensive wheel. Well apparently I missed the fact that they were moving to a new location (probably in a back issue I haven’t gotten to yet..if I can find my Car Craft pile again”). All I can say is “WOW” and “the Auto Magazine business must be paying good”, because their new garage is to die for!!! Really, how did they ever survive without an ocean front garage in El Segundo, Ca. where, while you are on your lunch break, you can catch a bite to eat, a Pepsi and a wave ???!!!!! With a few more earthquakes my Arizona home might one day be ocean front property.
O.K., fine, so a quick Google shows the Car Craft garage address isn’t actually on the beach and really location isn’t my point. What is, is the article that Mr. Douglas Glad wrote in the “Front Man” section – “Man Cave”. Specifically a couple of items, he believes are necessary in a garage. He states “…every car guy’s garage needs the basics to be useful and a good place to get away from school, diapers,….” Hey, I get that, I was a stay at home Dad for a while and sure, you must have the tools to get the job done. I was really interested to read what he thinks we average car guys (I just tossed in the “average”) need in our garages. But at the next paragraph’s bold heading, I stopped and said “What?” I then scanned the other six paragraphs’ headings and was dismayed, but I read on hoping I could salvage something from the piece.
First critical piece of functional equipment was a….MIG welder? Nope. How about a parts cleaning machine? Nope. How about a flat screen T.V.? Yes. But according to the article, it doesn’t have to be huge. So what’s next? I’ll just list them:
1. A movie collection of guy movies – I have an AM FM radio and CD player (old), most of the stations are static interrupt by parts of a song or commercial and the player skips. I’m normally so wrapped up in what I’m doing it just becomes white noise anyway.
2. A wall collage – If there is that much space on my garage wall, I’ve got some nails and stuff to hang from them and a Hemmings’ Muscle Machine calendar.
3. An art school grad’s, air brushed wall art – Same As Above
4. Electrical – 220 – Now I can get behind that. Right on!
5. Trosley Car Portrait – First WHAT!?!? Then…Same as 2 and 3.
So I’m taken back. My image of a greased smeared blue uniform shirt wearing, lay a wrench on it, magazine, has been crushed. Has Car Craft gone soft? Do they out source the work and just drive the finished project in for photo ops?
Am I shocked and dismayed or just jealous? The latter!!!!
I dedicate this to a follow car guy who I purchases some used parts from a while back. Bill is restoring his dream car in a 3 sided building in the mid west, where in the winter, he normally has to shovel snow out of the way to work on it. You rock.. Bill!!!
While I’m currently working on the project plan for all the modifications, I still get the urge to spend a beautiful winter’s day doing some wrenching. Oh…here in southern Arizona you wait for winter days like today, Sunny and near 70 degrees…oh yes..perfect day for being outside and working on your projects. ( Don’t hate me ’cause I’m warm!!!)
Modifications pending, there are still little things that can be done. A few weeks ago I noticed a loose fender bolt. Now normally these bolts are screwed in to clip/slide on nuts (some times called “short nuts” but I just couldn’t put that in the title) that are slid over the edge of one of pieces you need to hold together.
Slip-on or Short Nut
So if a bolt becomes loose it is often the cause of vibration, and if left unattended you can actually loose the slip-on nut. Unless…..it doesn’t have one and a traditional nut has been used.
A while back I ordered a couple of bags of bolts and short nuts for my Mustang and today I decided to spend a few minute and replace the loose one and check the others.
What I found was a bit odd. Three of the bolts on right fender (do I have to say right “front” fender? I hear that all the time, but I grew up knowing that fenders were in the front and quarter-panels were in the rear.) did not have the short nuts, but rather the tradition bolts. I checked the left “front” (just in case) fender and found them to all have slip-on nuts.
I can understand that some where in the 41 year life span (Oh…incidentally..I’m technically the 3rd owner, with the to previous owners beginning a mother, daughter combo) of my ’70 coupe that someone took it a part, lost the slip-on nuts and yes it was just a driver car so that’s possible. However, on closer inspection I noticed that the normal slots that would allow the assembler to slide the short nut on were not there for the three bolt holes at the front of the fender (or at the front of the front fender….ok sorry, enough of that).
Square Slot that allows for the installation (Left of the bolt)
Bolt Holes without the slot.
So I wondering how much after-market parts are actually on the my Mustang. When I had the car repainted, we did discover that the right door was replaced (paint underneath was blue) so why not the fender? The options I have are to, remove the entire fender and if the holes are not blocked by aftermarket fender then I’ll have to consider using the traditional bolt and nut or I’d have to cut the slots.
Now that’s not the only aftermarket issues I discovered. Those two bags of bolts and short nuts…..yeah..they aren’t the right size. Although the are sold as “fitting 1968-1970 Mustangs” the original are 1/2 ” nuts and these are 7/16″. Well yeah..they’ll fit…heck there are all kinds down the street at ACE Hardware that will fit too!!!
As part of the mods and upgrades for my 70 Mustang, I plan on replacing all the carpet. Before I do that however, I’m going to lay down some heat and sound proofing (but that is another post).
As I start project planning, I’m looking around for parts and materials, as well as any helpful hints. (If you have any at any time, drop me a comment.) Although certain portions of the restro-mod will have to be done together, like carb and intake or heads and cam (yes I’m all four will be done at the same time), many can be accomplished separately, like adding the heat/sound proofing and the carpeting, before upholstery of the seats. In the Mustang getting the seats out are easy enough (keep in mind my goal is to not have the car tied up too long between stages) so replacing the seats after the carpet installation, isn’t a problem.
As a reminder, the mods will be done in adherence to budget, time and events. So there maybe a need to move between different phases to accommodate either 3 of those factors.
O.K., so where was I, oh yeah..carpet shopping.
As I looking on-line for the best place for ordering carpeting, began to notice a lot of choices. I start thinking “I’m going to have call up on deck my personal award-winning interior designer (that would be my wife – by profession…no not wife by profession although I’m sure thinks it’s her 3rd career, but Interior Designer by profession). Here is a little bit of what I found:
Plush Cut Pile
Ultra-Plush Cut Pile
Neon Cut Pile
100% Nylon Loop
I’m thinking, “holy cow!!!…What the heck is this?!! Ultra-Plush Cut Pile? I’m not building a ’60 Love Van!!! Oh it gets better..yeah.. you guessed it samples!!!!!
Misty Gray
BuckSkin
My favorite - Cinnabar
Oh..come on!!! Cinnabar!!!! Really!!?? Um..yup. Oh and there were many more, like Medium Gray and Silver Mist and Nutmeg and Fire Thorn!!!! I’m not kidding.
So I’m looking round to make sure know one’s looking over my shoulder (as I’m doing this over my lunch at work..on my personal smart phone…just in case “they” are reading!!!) All the time I thinking…”It’s black..all I know is that it’s black!”
Who knew that there was that much to look at? Not this Average Guy.
Luckily I found this snippet on one site and it all became clear:
Plush Cut Pile
Our nylon cut pile is constructed from 100% first quality yarn and is similar to what is found in most cars since 1974. It is tufted on a 1/8 gauge machine with 14 ounces of yarn per square yard. It is dyed using the finest dyes available and tested for ozone humidity fading & light fastness.
Ultra-Plush Cut Pile
This carpet is a super plush upgrade to our standard Cut Pile. A 100% nylon cut pile manufactured with over 40% more nylon fiber than our standard cut pile. It is dyed using the finest dyes available and tested for ozone humidity fading & light fastness.
Ok..still not sure here!!!
Neon Cut Pile
Our Neon Cut Pile colors are a great look if you want to make a statement! Although these are not stock colors, they would be appropriate for all applications. There is an additional 15% charge for all applications made with Neon Cut Pile.
What…not stock colors!!!??!!! What? Are you sure that is color
wasn’t stock? It’s Pink!!!!
And the clouds parted and it all became clear. The very last one was this:
100% Nylon Loop
A 100% nylon loop. This material is appropriate for pre-1975 applications only, and was the original type construction used in 1969-1973 Mustangs.
