Engine Line Up – 1946 Packard

By | | , , , ,
Leave a comment

I love writing Engine Line Up pieces. I learn a lot doing the research.

Back in 1946 there wasn’t a lot of imagination when it came to naming cars. Packard either named their cars after the engines that powered them or their engines after their car models plus the cylinder count. This led to the following models names:

Clipper Six
Clipper Standard/Deluxe Eight
Clipper Eight
Custom Super Clipper Eight

The engines available for the Packard line up included one 6 cylinders and two 8 cylinders.

First up is the 6 cylinder dubbed – Clipper Six. This was an inline (straight) L-Head 6. (Note: An L-Head is a type of internal combustion engine having both inlet and exhaust valves on one side of the engine block – making the shape of an “L”.) The engine displaced 245.6 ID and had a bore and stroke of 3.5×4.25 and a compression ratio of 6.7:1. It had four main barrings and solid lifters. Top it off with a Carter WA1 single barrel carb (Model 530S) and you’d get 105 hp.

Clipper Six Engine – 1947 would be the last year this engine would be used in the Packard

Next up is the inline eight, referred to as the Clipper Standard/Deluxe Eight.  It was an L-head as well that displaced 282.04 (yes .o4) cubic inches.  It’s bore and stroke were 3.25X4.25 inches and the compression ratio was 6.85:1.  It had five main bearings and solid lifters all topped with a 2 barrel Carter (WDO) Model 512S.  On a good day you could coax 125 hp out of this configuration. Consider that the average weight of the Packard’s for that year 3,922 lbs with the heaviest being almost 5,000 lbs (4900), you’ll need all those horses to get these beautiful pieces of steel moving.

Last is the Super/Custom Super Clipper Eight.  Again it was a straight (inline) eight cylinder and an L-head.   This power plant was 356 cid with a bore/stroke of 3 1/2×4 5/8 inches, 9 main bearings and hydraulic lifters.  Topped with  a Carter’s (WDO) two barrel Model 531S it produced 165 horse power.

This isn’t the greatest paint job but I love the front end of this 1950 Ford F-3.

Love the hood!

The bed has been nicely done.

Not a great shot but the stake bed is nicely done. This Truck still see a good it of work

The first F-Series truck (known as the Ford Bonus-Built) was introduced in 1948 as a replacement for the previous car-based pickup line introduced in 1941. The F-Series was sold in eight different weight ratings, with pickup, panel truck, cab-over engine (COE), conventional truck, and school bus chassis body styles.

The F-3 became the F-350 in 1953.

Your engine selections were:

226 CID 3.7 liter I6

239 CID 3.9 liter Flathead VI

254 CID 4.2 liter I6

337 CID 5.5 liter Flathead V*

Next-Gen LT1 6.2-Liter V-8 for 2014 Corvette Revealed with 450 HP, New Tech – WOT on Motor Trend

With the new C7 just days away with from it’s reveal – will it look the a Camaro or not much of a change from the C6?

We  don’t exactly know, but what we do know it will have the GM small block a mainstay for 57 years.  This version will be almost all new and dubbed the “LT1”,  (after the 70’s engine) and will be naturally aspirated with direct fuel injection (the first with push rods).  The idea is that the base Corvette will have 450 hp and 450 lb-ft, compression will be 11.5:1 and get 26 miles per gallon (yeah….RIGHT!!).

Read some more at the link below and in the Feb 2013 Edition of Motor Trend read “Up Close and Personal With the LT1” (page 15).

Engine Line Up – 1956 Hudson Part I

By | | , , , ,

Think there was much of a choice of engines back in 1956?  Well there were a few for the 1956 Hudson.

As was custom back in the 40’s and 50’s, the engines were often named similar to the model of the car they powered.  For the 1956 Hudson, the company had the Hudson Rambler, Wasps and Hornet.  The engines followed suit for the most part.  There were 5 six cylinder versions and 2 V8s.

The first up is the Hudson Rambler Six.  This was an in line 6 L head with a displacement of 195.6 cid.  It was a cast iron block with bore of 3 1/8″ and stroke of 4.25″
and a compression ratio of 7.5: 1.   The four main bearings, solid valve lifters and 1 barrel Carter Carb (YF model 2009s) combined to produce 120 horse power.

’56 Hudson Rambler In Line Six

 

The Wasp Six was a In Line L-head 6 cylinder.  It to was a cast iron block same compression ratio 7.5:1.  Its bore and store was larger than the Hudson Rambler – 3.00 x 4.75 (vs. 4.25) and it manged to displace 202 cid without a change in hp still at 120.  The engine came from the factory with a Carter one barrel WA-1 carb (2009s).

 

The Wasp Twin-H Six was similar to the other Wasp except it managed 8.0:1 compression ratio with the help of the H carb configuration.  This consisted of 2 Carter single barrel carbs (WA-1 model 2013s) that helped the 202 cid engine produce 130 hp.

This is another from YouTube.
As watchmaker in a past career I can really appreciated the skills it takes to make this engine.  Having it run when it’s completed is priceless.

Six Cylinder Super Charged

By | | , , , , , ,

Technology has come a long way in the car world.  Early on getting 100 hp from an eight cylinder was tough, much less from a six cylinder.   Now days you can get a V6 Mustang with a base horse power for up to 305.  Add a super charger and you can squeeze out 427 hp from the same engine.  Yes technology as come a long way.  Really?That’s what I would have thought. Super charging has been around in the hot rod, drag racing world, for some time, but in a production, oh that’s fairly new (last 10 years or so).  But reading an article from Hemmings Motor New dispelled this notion I had.

So you’re thinking how far back was super charging something for sale to the general public, 60’s maybe…70’s maybe?  How about 1937?

Yes.  A car company by the name of Graham produced a 6 cylinder coupe.

1937 Graham Coupe

Supercharger badging

That’s a nice looking coupe.  Here is a shot of the super charged straight 6 and one of the charger it’s self.

 

Straight 6 cylinder.

 

 

The supercharger. This was Graham own design of a centrifugal super charger which they manufactured themselves.

They used this first on their straight eight engines then on the straight six.  They preformed so well that they nearly equaled the power of the eight-cylinder.  The car was lighter with the smaller engine and that helped it hit 60 mph in just 14.5 seconds by producing 112 hp.  The car came into chassis lengths 116 inches which had 106hp, 199.1 cid straight six and 120 inches which had 116hp 217.8 cid straight six.  What about gas mileage? How’s 23.95 MPG grab ya.

Formula 1 Engine calculations

I wanted to share something I did related to piston speeds. As you know Formula 1 is near the pinnacle of technology in engine development. Back in 2003, I read an article about how the BMW Racing team developed their engine. The article stated they were very proud that for the 2003 season, their engine was a 3 liter V10 design which had a maximum racing RPM of 19200 and the piston sustained a maximum piston speed of 40 meters per second (which equals 7872 feet per minute maximum). The article further stated their piston sustained a maximum acceleration of 10,000 times the force of gravity at maximum revolutions per minute.

I was always curious about the bore vs stroke for such a small displacement, high revving engine, but they always kept that secret. I grabbed my old Dynamics book and realized I could solve for bore and stroke by two methods, using angular velocity and again by piston acceleration.

Please note, I found a typo on Page 1. It says VA and VB are parallel, when clearly it should be written VB and VC are parallel.

Enjoy and discuss!
