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?
