3/1/1988 Pontiac announces the end of the Fiero automobile – Was anyone sad about that?
Pontiac Fiero
3/1/1937 In New Jersey one of the largest dealerships of the era was opened. The Miro Brothers opened a state-of-the-art facility with “one of the largest and most modern showrooms in the country,” measuring 38′ x 40′ . The dealership was service station and dealt for Buick, Packard, Oldsmoble, and REO trucks. The east side of the building served as a Mobil gas station and service garage during the World War II.
I love History, always have and I love engines. I find learning about an engine’s history, its development and how and where it was used over time a great past time. (In case you are unsure of my sincerity – check out my to engine series on Mopar’s 318 http://wp.me/pKHNM-gW and Chevy’s 283 http://wp.me/pKHNM-nu http://wp.me/pKHNM-nB http://wp.me/pKHNM
I also find fascinating, the involvement of U.S. car companies with the development of cars for overseas companies.
Ok..this is a larger introduction for a one of my “factoid” entries, but here they are:
– In the 1950’s and 1960’s the main player of Lotus was a guy named Colin Chapman (aka Anthony Colin Bruce Chapman – tossed that in there because in several of my reading variations of his name was used). Mr. Chapman was responsible for such cars as the Lotus 6, Lotus 23 and Elan. Having developed his own engines and now desiring to improve on their racing performance and btw he was also known to be a bit tight fisted with the cash. This all led him to use technology, as it was back then, that was already developed elsewhere. Give that propensity he used Ford engines for his cars and greatly (at least overseas) enhanced Ford’s racing repetition. The engines he used were Ford’s 105e and 109E engines the Cleveland and Windsor respectively.
Fords 105E used by Lotus.
– These two engines were sometimes referred to as the “Kent” engines.
– They were fitted with twin cams designed by Harry Mundy. These heads were aluminum with hemi combustion chambers sporting .375 lift, 264 degree duration shafts, 1.53/1.325 valve with 9.5:1 compression. All topped off with a Weber twin sided-draught carb.
– They were a starting point for Lotus and Ford racing development and were uses for experimental purpose as well as racing.
– Heavy duty use showed some flaws in the engines due to the 3 bearing mains, resulting in broken cam shafts.
– Was the impetus for Ford to developing the 116E engine with 5 bearing bottom ends, which was basis for the Lotus 1600 Twin Cam.

When installing a new engine or even modifying your present power plant fuel and intake system you have a few things to consider.
Of course the size of your fuel pump, where it and the fuel filter is located, size of the filter, size of your fuel line, fuel pressure. Along with that jet size or injector size and baffling in your fuel tank. All of this is important to ensure your fuel delivery system can maintain full pressure at peak engine horsepower in high gear.
All of these need to be adjusted or “sized” to accommodate less controllable factors such as Altitude, air temperature and idiosyncracies of your fuel, like quality and octane rating. Yes even specific gravity of your gas can effect the jetting.
Here are some jetting requirement of a 750 CFM 4 barrel Holley for specific fuel, temps and altitude options:
Octane Temp. Altitude Front Jetting Rear Jetting
94 80F 0 ft 81 86
110 Race 80F 0 ft 81 83
94 80F 3000 ft 76 81
94 80F 6000 ft 73 77
94 40F 0 ft 84 89
94 120F 0 ft 78 83
Oxgenated fuels toss another factor in to be considered when determining your jetting requirements.
Studies of shown that every 1 point richer in air/fuel ratio equals only a few percent less power. Running the engine as lean as possible will increase your power but also increased combustion chamber temp, which can damage your engine.
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.
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.
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.
10/4/1983 A new land speed record is set by Thrust2 a British jet propelled car. It was driving by Richard Noble and reached a top speed of 650.88 but the actual record was 633.468 base on the average of two runs within one hour.

Thanks for reading. Coming up more wrenching tips and the first installment of the next engine series featuring Chevy’s 283 power plant.
If you are work on your older cars engine, there are a good many tricks that you can use save a couple bucks and gain a little horsepower.
This one is an oldie but a good.
Have your intake valves back cut, you’ll get a similar boost as if you use high lift rocker arms or cam.
The procedure is best done by a qualified machinist. So while you have your engine apart and laying all around our garage on pieces of cardboard (come…you know that’s what happens!!!) have him take a little off the port side of your intake valves. This creates the same effect as an earlier opening a later closing action like just a like a the addition of a an upgrade cam. The lighter valve means less spring pressure is required to control the valve at higher rmps.
A 30 degree cut is what they do on vortex engines.
The backcut is at the edge of the normal valve cut.
