427 Truck Engine

A bit of nostalgia this morning. If you have been around this business long enough you remember, and perhaps you even sold GMC trucks with 427's way back in the day.

Here is the deal:

Back in the day a GMC or Chevrolet truck with a 366, 5 speed, 9 front, 18,500 2 speed in the back, 10.00x20 tires and a 27,500 lbs GVW was the standard of the industry. These trucks sold by themselves, they had such a reputation of being the best.

At one point GM truns the 366 to a 427, as an aside this was not the same 427 as in cars, it had a tall deck block, and was used in trucks and marine applications. Although the 366 was bullet proof. The 427's were not lasting as long. 

Numerous folks at GM were scratching their heads as to why a 366 would easily last over 200,000 kms in a truck and the 427 was barely lasting 100,000 kms. 

Here is another deal:

Been in the business long enough you hopefully remember a company called McCallum that was transporting GM vehicles from the factory or rail heads to GM dealers in eastern Canada. McCallum had a numerous tractors with 427's pulling their trailers. Yes...they did not last very long the 427's.

GM in Canada enlisted McCallum to run various tests on various configurations of 427's. GM will install an engine in a McCallum truck, have the truck cover a speciifc mileage, take the engine out, replace it with another engine. Obvious do a meticulous tear down of the engine taken out of the truck. Yes...the old tachographs were helpful during the tear down.

The conclusion...not enough gas flow, the 427 required appreciably more gas than the 366. The by now iconic single 200 liter step tank with an electric fuel pump for the 366 created instances of fuel starvation with the 427. The solution...dual step tanks with dual fuel pumps.

Another deal:

In Canada, a 427, with a 5 and 4, 12 front, 38,000 in the back, with an Hendrickson suspension was the standard dump truck for countless years.

At the time GM had the medium duty truck market "locked up" with the 366 and 427.

The last deal:

Yes...the 427 were strong performers on the highway, very strong. Fuel economy...don't ask.

The Joys of Winter Driving

What starts out as another winter road trip...with the exception that its a "little colder"...

Nothing out of the ordinary, the usual stretch of the 401 travelling east is very good...its all cool.

Now the return a few days later on the 401 west starts very innocently...and gradually deteriorates

The interesting feeling that what looks like cold wind blown pavement, is not what it seems..."why does the car seem a little loose..."

To being stopped on the 401, having an opportunity to get out of the car and confirm that the car is loose, since its ice, to the closing of the 401 from Prescott to Kingston in both directions. Its all cool fortunate to take an exit and spend time in a McDonald.

Then driving a distance on Highway 2 which is the original 401 from way back in the day.

To getting back on the 401, and then its shut down again near Napanee...another mission to discover, and follow the 401 EDR signs.

At Napanee on the 401 east bound its a war zone in all the lanes...

Trucks strewn all over the place...

Wondering what the 401 EDR looks like in full use?

The 401 when its shut down...

Yes we made it back in close to double the amount of time, and a few "white knuckle" moments.

Gaining more appreciation for the work all "first responders" do in inclement conditions.

As silly and old fashioned that it might sound, helpful to have a heavier coat, boots, gloves, windshield washer fluid, charged up smart devices...it might just all be useful on a road trip when you least expect it.

Bitumen Bubble

This morning we have The Colonel with us, our conversation revolves around the "Bitumen Bubble" and cars.

Q- Colonel Good Morning...what is the bitumen bubble?

A- Connect the dots, and its becoming more transparent that there is a lot of oil available, more than we thought a generation ago. Bitumen is the tar sands.

Q- Between the tar sands, fracking, shale, is North America floating on oil?

A- Its starting to look like it.

Q- If its becoming obvious that we are floating on oil, why are we paying so much for gas?

A- Taxes, upholding an infrastructure, we have shut down refineries, a whole bunch of reasons, but we are not running out of oil.

Q- What was peak oil? 

A- Imagine immense oil tanks in the earth, at some point one would reach the top of the bell graph, between finding new oil, consumption, and depletion. Once you reach the peak its a downward slide on the depletion side (emptying the tanks).

Q- Its no longer the case?

A- Does not look like it for the foreseeable future.

Q- How about the price of gas?

A- We have known for several years that when gas gets close to $1.50 a liter its the pain treshold, it will not go down to uphold the infrastructure, but it will not go up. Who am I to speculate on the price of gas.

Q- Will more stringent fuel economy progress?

A- Absolutely...its the right thing to do...from several perspectives...congestion being one.

Q- How will the auto industry adjust or cope.

A- Pick ups will keep on selling, small cars (fuel economy) might just stabilise.

Q- How about hybrids?

A- Hybrids are a propulsion mode, folks that prefer an hybrid electric propulsion will continue to acquire hybrids.

Q- Where do you see diesels?

A- Diesels, catalytic converters, urea injection, 1,000 kms on a tank, at some point the trade off, to not really needing a diesel in any passenger vehicle will be debated. 

Q- Are you implying that if a vehicle is not working/pulling a load a diesel is not required. 

A- Precisely, at a GVW of 3,000 kilos you don't need a diesel, cars, and SUV's do not reach 3,000 kilos at 3,000 kilos and higher a diesel becomes a consideration and at a certain point an absolute necessity.

Q- Where do you see gas engines?

A- We have known for some time that V12 would become V8's with turbos, V8's would become V6's with turbos, V6's would become 4 cylinders with a turbo, and 4 cylinders would become 3 cylinders with a turbo. Its all there with various manufacturers touting what fits for their particular applications.

Q- These turbo motors how good are they?

A- In cars they work fine, in trucks with light loads they work fine, once the loads start getting up there, would you rather have a V6 with twin turbos working away, or a naturally aspirated V8 working away, or perhaps a diesel.

Q- Where is fuel economy headed?

A- It will progressively improve, especially in city, congestion, surface street applications and usage of vehicles. 

Q- On the highway?

A- We all know that you need a certain level of power to overcome wind resistance, time is an increasingly precious commodity, folks tend to drive faster than slower, highway fuel economy ratings are calculated at speeds that no one drives.

Q- Is it fair to say that we might have to re conceptualise some of our thinking?

A- Some...we will have to re evaluation many of our established assumptions and beliefs.

Q- We can keep on going...but Thank You or your thoughts this morning.

A- Fascinating subject, its a start, although we had better stop for this morning.
