Engine Line Up: 1973 Ford – The 400s Part III

By | | , , , , , , , , ,
Leave a comment

Next up are the Ford 400’s that were available for 1973.

There were 3 options when it can to Ford’s biggest power plants in 1973, the 400 Cleveland the Thunderbird 429 and the Thunderbird 460. If you are thinking…YES!!! More Horse Power!!!! …you are going to be a bit disappointed, compared to today’s standard and the 1960’s standards.

The Cleveland had a cast iron block, over head valves and displaced 400 cubic inches. Its bore and stroke (4.00 x 4.00) and compression ratio (8.0: 1) were choked to death by the two barrel Motocraft carb. It produced only 163 hps

Wimpy - 400 2 barrel intake...needs a 4 barrel intake

The two Thunderbird engines (both cast iron with overhead valve) got the privilege of being topped with 4 barrel Motocraft carbs. The 429 displaced 429 cubic inches and the 460 knocked out..yup you guessed it 460 cubic inches.

They had a bore and store of 4.36 x 3.59 and 4.36 x 3.85 respectively and both had the same compression ratio of 8.0:1. The top hp for the 429 was just barely over 200 at 201 and the 460 out did that by 18 giving it a 219 hp.

Fords 460

 

429

 

Here is the twist with these and the rest of the Ford engines.  The horse power stated was changed depending what model the engine was used in.  Most of those in this series were the lowest stated.  For example the 302 was rated at 135 hp in the Maverick, but 138 in the Torino. (Yes, a whopping 3 more hp!!!)

The average difference was between 1 and 5 hps, so we aren’t talking about a bunch of hidden power as they were configured.  But we all know that you pop off  the that 2 barrel carb off any of these engines and plop on wide mouth Holley, and you were going to get much better numbers!!

Engine Line Up: 1973 Fords Part II – 351s

Here is the second part of this ’73 line up for the V8.

There were 7 V8 in 1973 (not including the Mustang engines) and the ranged in numbers from 302 to 460 (big number to be sure). Just reading those you think..OH…THE …POWER…NOTHING BUT 100’s RUBBER BURNING, FISH-TAILING HPs!!!…right….uh…NO….these ain’t 60’s engine and they aren’t 2010 engines..nope..they the 70’s engines.  Here’s how they ponied up.

The 302 – Overhead valves, cast iron block with a bore and stroke of 4.00 x 3.00.  Compression ratio of 8.0:1 with 302 cubic inches displaced.  Top that with an awesome 2 barrel Motorcraft carb and you are knocking out 135 hp’s!!!!  Those are number only a grandma could love.  Compare that with the 302 sold under the hoods of Fords in 1970 which yielded 220 hp with a two barrel carb. (Take that 302 bore it .030, toss on a typhoon intake and a 4 barrel Holly you’ll have exactly what currently have in my ’70 Stang.)

My Mustang's Enhanced 302

 

Next up is the family of 351s, the Windsor, the Cleveland and the CJ Windsor.

All three had overhead valves, cast iron blocks and all displaced 351 cubic inches.  They shared the same bore and stroke which was 4.00 x 3.5 and the compression ratios ranged from 8.0:1 to 8.6:1 and the horse power varied by rpm 3800 to 4000 between 156 up to 177, the Cleveland and baby Windsor were choked with a 2 barrel carb while the CJ managed to steal a 4 barrel of the assembly line shelf and had a compression ratio of 9.0:1.   The 351 CJ was able to come in a little more respectable with 266 hp at 5400 rpm.

I will tell you this there were very few 351 CJ Windsor made in 1973 and 1974.  I owned a 1974 351 CJ  and my researched showed that less than 100 of these engined were produced that year.

All of these were used in the Torino, Montego, Mustang, Cougar and other Ford and Mercury models.  The 351 CJ was used in the Mustang and Cougar.

Up next the 400’s for 1973.

Engine Line Up: 1973 Fords Part I

1973 was a good year, I was a still in high school and big engines weren’t extinct yet. Ford had a big assortment.  We are talking 10 to choose from if you didn’t count the Mustang engines.

Ford Pinto (this will be a parking log spot light coming up)

On small size 6 cylinder were still king but 4 cylinder was available for the Pinto.  For the larger engines displacement was large and the horse power small.

There was only one 4 cylinder available, reserved for the ill fated Pinto.  It sported an overhead cam and iron block.  It displaced a whopping 122 cubic inches and as one would expect had the smallest bore and stroke – 3.58 x 3.03.  The compression ratio was 8.2:1 and it tore up the street with 86 hps.  (No I didn’t for get the “1” in front of that.)  It was topped with a Ford/Weber 2 barrel carb.

2.0 Pinto Engine

The six cylinders came in 2 varieties  and were used in the Maverick and Torino.  The first was dubbed the Maverick 6 cylinder. It was configured with overhead valves and a cast iron block.  With the bore and stoke 3.68 x 3.13 it was able to displace 200 cubic inches.  The compression ratio was slightly higher than the 4 cylinder at 8.3:1 but it was fitted with a 1 barrel Motocraft carb resulting in only 84 hp.

The second ‘big brother” six cylinder was called the Maverick/Torino.  Again it had the overhead valves and cast iron blocks, same as its little brother, but it had a greater stroke 3.91 (3.68 X 3.91) compared to the its sibling 3.13.  The compression ratio was lower (8.0:1) and topped with the same single barrel carb it managed 88 hps.

The Torino was not a small car so it really need those 4 extra hps!!!

Ford 6 cylinder - nicely restored!!!

V8s  for 1973 coming up and then the Mustang engines.

1971 Chevy Engine Line-Up Part II – The 454

By | | , , , , , , ,
4 Comments

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 American V-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.

Thanks for the spark to follow this up Bill.

Engine Line-UP: Chevy Engines 1971

By | | , , , , , , , ,

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.

1967 Olds F-85 Club Coupe Restoration

By | | , , , , , , , ,
5 Comments

I bumped in to Bill Holtzclaw from Cartersville, Georgia, virtually (Facebook) and he shared a few pics and some detail on his restoration of a 1967 Olds F-85.

Bill's F85

“I am doing a full, frame-off restoration on this 1967 F-85 Club Coupe. It has a convertible frame, 442 suspension, steel crank 330, .030 over with W-31 cam and 2” intake valves, close ratio Muncie 4 speed and heavy duty 3.91 posi rear. It is a radio delete, heater delete, carpet delete car with the factory cloth and vinyl interior. The drive train is built and the chassis is being assembled. The interior is done, the chrome and bright work is done. Next, we’ll pull the body and put it on a rotisserie. It will be two-tone Crystal and Midnight Blue.”

“I’ve had a lot of interest in this project from some of the leading Oldsmobile collectors in the country. It is my version of what would have been a 1967 W-31, which was introduced in 1968. All of the parts to build this car back in the day were available as either RPO options or over-the-counter upgrades. The W-30 package was available as an over-the-counter package in 1967. The W-30 cam and the W-31 cam are one in the same, and the OIA kit will work for both small block and big block cars. So, it was a possibility! ”

The upholstery turned out awesome! He used NOS fabric for the seat inserts. The car was a factory carpet delete car with a near-perfect vinyl floor covering. “I cleaned it and had it dyed the color blue (same as dash pad) that I wanted. It looks absolutely brand new! I had seat belts custom made to stock appearance, and the standard steering wheel came out nice, too.”

Check out the vinyl floor covering

“I had the gauges restored by R&M restorations in Greenville, SC. The odometer was re-set to zero.”  The dash bezel was restored by Chrome Tech USA. They repaired the 44 year-old plastic, re-chromed it and then detail painted it. The radio and heater delete plates were purchased from Red Venom Enterprises. “They only make the radio plate, so I purchased two and trimmed one to fit the heater control panel and the PRNDL panel. ”

Bill did the polishing himself

He installed a Sunpro Mini Tach in place of the factory clock. Looks like it came from the factory that way!

Great Job - Bill!!

 

Final Product

 

 

Bill is also the owner of a 1967 Oldsmobile F-85 Town Sedan with “Police Apprehender” package.  It has the HiPo 330/320 hp, Heavy Duty Jetaway and 442 suspension upgrades.

Nice!!!

Might be why he’s known as OldsMoBill.  “I am also known as the “Oldsmobile Police”!” Bill states.

Bill, I hope you check back with your status from time to time and thank you for sharing.

Cars You Never Heard Of! Part 2

By | | , , , ,

Thanks for all the comments and emails on the Part 1 of the Cars You Never Heard Of.

Thought I’d follow it up with the Panther Kallista.   This stems from the same article  in  “Classic and Sport Car” a UK publication.  The article pitted  pricey European cars against less expensive cars and rated them.  It’s over all theme was “See you can get this close to the expensive cars, for less.”

 

1985 Panther Kallista

Kallista was the product of the Panther Car Company and they were built between 1980 and 1990, actually coming on the market in about 1982.  The were a box chassis with an aluminum body.  The engine that was first used was Fords 2.8 V6 which cranked out 2792 cc from its 12v configuration.  The electronic fuel injection helped it deliver 150 hp and 159 lb ft of torque. Top speed was about 120 mph with the help of the 5 speed manual transmission.

It had an independent wishbone suspension, rigid axle, rack and pinion steering with disc brakes in the front and drums in the rear.

In the article Kallista was compared against the Morgan Plus 8 which you can purchase now days for about 35,000 British Pounds (about $70k US) compared to the collectors price of 7,000 BP ($14k US).  In that contest comparing Driving, Practicality, Character, Value and Usability the Morgan was judged with a total of 37 points and the Panther Kallista end up with 35.

I did find one on Ebay with a few days still to go with a current bid of just over $4k.  It’s an 1986, 4 cylinder – not a V6.

The Marauder

I like off –beat cars. By that I mean, the ones nobody thinks about immediately.  Some of those are cars like, Studebakers, Edsels, and Mercurys.

A few years ago, actually shortly after we moved to Tucson, AZ., I was at the local Safeway and I saw this black car moving through the
parking lot.  I was on foot and I hurried to the end of the parking row to see if I could catch the manufacturer and
model.   To my surprise that sports-roof-like, long black car was a Mercury Marauder!!  It was beautiful.  I’m still not sure what
year it was but I believe it was a 1969 and possibly an X-100, but I can’t be sure.

'69 Marauder

I’m not totally unfamiliar with Mercury’s, having lived with grandparents who  for years would only buy
that Ford brand – mainly the Marques and other 4 door models. Frankly back then I wasn’t all that impressed.
But the Marauder, like the Cougar, wasn’t your grandparent’s car!

So coming up is my write-up on the Mercury Marauder.

Leave a comment

Jump back to 1934 and lets see what the auto makers cold crank out.

Ford was the leader over Chevy but only by 12k cars, 563,921 and 551,191 respectively.

Plymouth was third with 321,171.

Dodge was a distant fourth with 95,011

Hudson/Terraplane produced 85,935

Oldsmobile only 79,814

Pontiac just slightly behind them with 78,859

Buick finished up last with 71,009

What else was going on in 1934:

–  Hudson dropped its six banger

– Lincoln put V12’s in all of their cars.  The 414 cid carried a 6.3:1 compression.

– Graham produced the supercharged Custom Eight.

Graham's 1934 Custom Eight

You know I love engines and this Custom Eight is great!!

Wrenchin’ Tip – Got 6 Volts?

By | | , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

I was recently talking to a coworker of mine who own a 1949 Pontiac Silver Streak Delivery Van (link –     http://wp.me/pKHNM-Bx ) and we were discussing his 6 volt system and the troubles with low amperage.

Well I just ran across a couple of interesting articles dealing with that subject.  Now I will tell you I am not “the guy” for electrical work – nope not me (I had a bad experience – ok – a couple of bad ones).  But even this one I can understand.

Increasing the power supply often means that you need to convert to 12 volt and maybe 15 years ago yes, but now 6 volts are readily available.  So here is what you do (sorry no pics)

Take two 6 volt batters and link them in parallel by connecting the two negative terminals to each other and the two positive to each other. The main positive cable goes from the positive terminal of the first battery to ground and the main negative cable is connected to the negative terminal of the second battery.  Of course in some case you may have to modify the batter shelf, but it will sure help kick up the cold cranking amps.
