Factory fitted Holley

My GT5-S came with a factory Holley 600, vacuum secondaries.

I have it sitting on a shelf along with the factory intake and heads and stuff... It's right next to my bent pushrod collection.... (no relation between the two!)

Is that a model 1850?

I will check my Deauville for the number. I know it's not a pantera but it did come with a holley double pumper. My car is a series 1 1/2 build in 1978.
Looking back in time I can recollect that my dad had a series 1 Longchamp with a holley DP. That one was from 1979 and he bought it when it was two years old which makes me doubtfull that it was retrofitted.
I also know that it didn't show up as an option on my car or the longchamp on the build info given by the factory. It does sound possible that some importers requested it as standard for all DT cars and not just panteras.
There are still some first owner panteras and deauvilles around in Holland. I for one would love to have a chat with them but none of us have had any luck with that so far. But never say never!

Charlie, I don't understand why you had so many bent pushrods with a hydraulic lifter cam? Apparently an American high school kid knows more about
Aerican engines then Detomaso's mechanics.

Doug -
It's a REALLY long story, but the bent pushrods didn't come from a factory problem. I had the engine rebuilt and installed a solid lifter cam... the problem didn't come from improper valve lash, but from poor preparation of the Aussie quench heads I bought from California.

BUT, that being said, while I was still suffering from bending pushrods every 500 miles, the DeTomaso mechanics diagnosed the problem and fixed it by changing my headers. For $1800.

Either the valve spings were binding because the didn't match the lift or the valves were binding in the guides, or the valves were hitting the pistons because of the lift. Those are the only items that will bend the push rods.

Yes, Yes, and No. At least in my case.

After installing the correct springs, after preparing the heads properly in the area under the shims, after fixing the problem with the guides that was side-loading the pushrods, and after I don't remember what else, I haven't bent one since.

Somewhat not surprisingly, despite DeTomaso's diagnosis of leaky headers bending my pushrods, their repair did nothing to help the problem...

As posted previously in the Engine Section; that's my original GT5 setup from the factory:

- Holley 700 DP
- Street Dominator manifold
- Bone stock OC Engine
- approx. 14 mpg

In general, it's quite a lazy engine. But as long as it runs like a VW Beatle, I don't want to change to much on the curent set up.

Roland, I think I personally helped the factory survive SEVERAL months... (that wasn't my only experience there!)

Hey, it's only money.

Oh you were the one Charlie! Thanks.

I'm still interested in the answer to the original question posed by Derek, "...European market Pantera were fitted with Holley 650 carbs by De Tomaso.What model Holley did they use?"

Below is a picture showing where to find the list number if that helps.

thanks, George

George that sort of looks like my carb, but way littler. Mine is really, really big. Embarrasingly so. Or maybe you have really bigass hands? Can you palm a basketball by anychance? I can and my hands can't cover nearlt as much on my carb as what yours are on that one. Maybe mine is like something from a 1940s fighter plane or something. It must be some junkyard thing, or maybe holleys first attempt at a carburator????

DOH!! Ok mystery solved thatnks to Georges picture. What he didn't say that he is pointing to the fron of the barb, not the back. To see them numbers you have to be in the drivers seat looking back and shining a bright light at it. SO my euro-GTS says it is a Holley 4777-4, when you look in the book of Holley it says that is a 650 CFM and it says it will not meet emisions and to use it for "off road." Must mean it is used for tractors and earth moving equipment and such.
ANyway thanks for everyones help, mystery solved and I sure do appreciate your help.

Here ya go George,
Took me a little while to find where I had it stashed, but this was the stock carb on my '85 5-S. You wanna know about the intake?? ;-)

Another view - note the rubber-stamped numbers... No idea what they mean

And the last one, showing detail of the model number.

I found it interesting that it did not have an electric choke - it had a hot air choke, with lines that ran into the intake manifold...

Must mean it is used for tractors and earth moving equipment and such.

DT, what kind of tractor do you have?

Nothing but the best for Detomaso Charlie. How much did they charge you for the new one? $2700?

I didn't buy the replacement from DeTomaso... I pulled the stock carb off when I put new heads, intake, cam, etc on a few years back and sourced it from one of the Pantera vendors. It took a while to get the carb jetted properly for my application, and I ended up sending it to someone to sort out for me as I just couldn't get it to run right. He did a great job...

As far as DeTomaso and their options go, DeTomaso offered the "Sport" option on the late-model cars. As far as I can tell, this option consisted of a different intake and carb. Their sales brochures claimed 300hp for a stock Cleveland, and 350 for the Sport option.

I personally know of one individual who bought their car new from DeTomaso in 1989... He paid $4500 for the sport option, which he was told not only involved the intake and carb, but also different internals (cam, etc). and was supposed to be good for 400 hp. When he rebuilt the stock Windsor 3 years ago, he found a bone-stock interior... Stock truck camshaft, stock heads and springs, etc. We all know they played loose with their numbers...

Don't forget to look for the block casting number when you are under the car.
The Ford numbers are above the starter.
If yours is a cleveland, it would be interesting to see what the "australian" block is in your car?

Charlie your number is differant from mine. I bet you have a better one than mine cause mine is so much older.
I don't have a tractor Doug. I have a push mower. My property is too steep for a tractor. Heck I usually fall down the hill at least once a year mowing as it is. I have what you call "vertical realestate". It means my property is one side of a mountain. It looks pretty unitl you go to mow it, then it is kind of a nightmare.
But getting back to why off road?? Maybe it was made for lambrogini?? They used to make tractors. Maybe DeTomaso used some spares mr. Labrogini had sitting around?? Who knows??

I inspected the carb on 9138 and it apears to be a 600 holley but the intake manifold looks like a Spread Bore style carb was stock. Meaning the secondaries are larger then the primaries. Further investigation will tell the tale.

Ron

Ron is that an alloy intake, or a cast iron?

De Tom,
I bought a new Holley 1850 600cfm.
This is marked as 'for off road use only' - but this is just to avoid the emissions legislation in some areas (e.g. USA and especially California). These older carb designs are not designed to meet current legislation.
For pre '75 cars here in the UK the law just demands a visual check of the smoke from the exhaust, no measurement.

Mr. Rapier, do you guys have smog over there in England? I was in Ireland once and didn't remember there being smog, but I would think England has more population density.

Nah, at 7 bucks a gallon we can't afford it.

Seriously,
Since they banned the burning of coal in London there isn't really any proper smog.
Air quality gets a bit c**p in London, Birmingham, Manchester etc on quiet summer days but I've never really noticed any.

Well what do you think all that green stuff is in Ere?

That carb of Charlie's (list 7154) looks like it's a metering plate on both sides instead of a block with jets - is that so?

Charlie & DeTom, thanks for posting your carb data.

DeTom yours is a 650 cfm model 4150 (double pump, mechaical linkage, dual metering blocks).

Charlie yours lists as a 600 cfm model 4160 (single accelerator pump, vacuum secondaries, secondary metering plate).

Charlie, I can tell you that your Australian sourced motor has heads with 2V sized ports and open combustion chambers. I am assuming it is a late model motor, therefore the oem ignition was a Bosch breakerless system and the original carb on that motor was a spread bore Carter Thermoquad mated to a cast iron spread bore intake manifold with small 2V size runners and exhaust gas recirc. That intake was probably removed by DeTomaso and replaced with the Holley street dominator.

How did I do?

\hey George,
First of all, congrats on the 1900 post level... That's pretty exceptional!

And congrats on your "guess"... you are pretty much right on! Those heads are in my guest room closet, as they have been replaced with 2v closed chamber Aussie heads. I honestly don't remember what ignition I had. The stock distributor is in another closet at home. And you were right on - DeTomaso installed a Holley Street Dominator, which is sitting on top of the stock heads in the guest room closet.

It's 6pm over here - I'd say you won yourself a beer!

Its 8:45 AM here on the west coast Charlie, can I put that beer on my corn flakes?

One other detail I could have thrown in, if I'm correct that your motor was a late model Aussie motor, the block & heads would have been painted black, the valve covers & air filter would have been painted silver. The early model Aussie motors were Ford blue.

take care

Pretty darn good George. Almost spooky. But now geuss what color eyes I got.

Ha, ha, ha....

OK DeTom, I've got the eye question partially figured out!

One of them is brown, the color of the other two I have no idea.......

Karnak, your all knowing friend on the DTBB

Yes George, I am a quart low.

George its an Cast Iron intake. What I was wondering if it was a spreadbore intake did it come with an Autolite Carb or a Holley ? One side looks like a standard intake and the other like the secondarys are larger. Today I took the air cleaner off and laid a blanket in there and was about to take it apart and said to my self "no way" if I take it apart it will turn into a compete resto. I already have one of those going on. LOL over the weekend I may get up enough nerve to investigate further.
Ron

OK Ron, a real quick run down on the Aussie Clevelands that deTomaso had to draw from.

First, Australia never cast ONE large port (4V) head, ever. All the 4V motors in Australia were imported from the US between 1970 & 1974; they imported M code, R code & Q code motors. There were stock piles of spare M code & Q code motors remaining in Australia after Ford ceased importation in 1974.

The Australian manufactured 351C with 4 barrell carb had heads with 2V size ports and open combustion chambers. That's the only way they made 'em. The popular Aussie heads with 2V ports AND closed combustion chambers were all installed on the 302C. Australia manufactured a 302 cubic inch Cleveland as well (3.00 inch stroke & 6.02" rods).

The Australian manufactured 351C 4 barrel carb motors were first equipped with the Autolite 4300A carb, 600 cfm, square bore design. These went into Falcon XB models ('73 to '76), the engines were Ford blue. The Falcon XC ('76 to '79) also got a blue engine, but Ford swapped to a Carter Thermoquad spread bore carb. The Carter Thermoquad has a hole pattern like the Rochester Quadrajet, the primaries are spread far apart. The Autolite 4300D spread bore carb has primaries that are nestled close together, therefore the Autolite 4300D carb will not exchange with a Thermoquad. But the Quadrajet will. The 351C 4 barrel motors installed in the Falcon XD ('79 to '82) and XE ('82 to '84) also had spread bore carbs. The motors were "metricized", the air filter decals read 5.8 liter. The metricized motors were painted black, the valve covers & air filter were painted silver. The engines were more smog tuned in the XD & XE Falcons too. The Cleveland was last produced in 1982, last fitted in the XE Falcon. Remember, all of the engines above had small 2V size intake & exhaust ports & open combustion chambers. Somewhere along the line, I'm uncertain with which Falcon model, a Bosch electronic distributor was added. The Bosch distributor had a slightly smaller shaft than the earlier breaker point distributor. This means the hole inside the block that the distributor shaft mates with is smaller diameter, and US distributors don't fit unless the hole is machined larger.

Australian Clevelands left over after 1982 were sold to deTomaso and, in a twist of fate, exported to the US.

Study hard, you will be quized.

Your friend on the DTBB

George.

Thanks ... from what I see from arms distance .. the heads have the little 4 up in the corner near the valve cover ... the owner had a paint can in his hand so I'm not sure of the color .. its dark blue ... so black could have been the base coat .. it has a set of factory alum valve covers but not detomaso's. It has a Hall Pantera upgraded ingnition system to a Duraspark ... I'm very curiuos to see whats in the car. I have to say the car is much faster then 6479.

> Australia never cast ONE large port (4V) head, ever

Actually, they did but not for production engines. When the inventories of
4V heads ran out in the mid-seventies, Ford Australia cast another batch in
1976. The 1976 re-casts were modified "D1AE-GA" castings and will bear that
number under the intake ports. They incorporated revisions to minimise
warpage, especially at the ends of the heads where the large square holes
meet the block surface. These heads were machined asstandard 351-C 4V heads
(Part # D1AZ-6049-B) and also as Boss 351 heads (Part #D1ZZ-6049-B). Both
used the same common casting, differing only in rocker pedestal and spring
seat machining differences. The casting dates were typically June, 1976.
There was also a further production batch made in March of 1978, these
supposedly had a little more meat added to backs of the chambers (directly
under the rocker pedestal) to minimize flexing under the the rigors of NASCAR
abuse.
