First four pics are what is on the truck. Second four is of a extra one that came with the truck(I am assuming it is the original one and is in need of major work)







Here is the bad part about a motor that is unknown for sure. The book shows one like this but this one does not seam to have a idle mixture adjustment screw that the book says it should







The book shows one like this one as the original that was on the truck when it was new. So should I try to rebuild this one and put it on it or even better question would it actually work with motor that is currently in truck with out needing a lot of modifications. And of course the pics in book are not that great.

Any ideas

 

You may want to write an e-mail to Ross (ALBUQ F1) he seems to know alot about these carbs.

In the mean time I'll bump this back up to the top for you to see if it will get some responses this time.

 

Hard to see with the size of the pics but does it have any ID markings?

 

The top pics appear to be in the Holley 94 family... as mentioned, any markings could help narrow things down. The other, and this is a guess given the picture size and quality looks almost like the Holley "towering inferno" or 4100 model.

I am not a good guesser, so some details would be helpful.

guessing hard, himmelberg

 

Here are the only numbers I have found on either carb. First one had 8BA 9515 next to one of the idle adjust screws on driver side. 94 stamped on the back side by firewall. And the second one that looks like what is in the book has these numbers stamped on it. EAC-9510-E2 list-694. Any help would be greatly appreciated.

 

The pics are too small to be of any help for these old eyes, but the numbers say the top one is Ford/Holley model 94 as stated. It mounts to the intake with 3 bolts in a triangular pattern.

The bottom carb by your numbers is a 52/53 mercury carb - the teapot. It was a strange looking thing and the base mounts to the intake with 4 bolts in a rectangular pattern. It won't fit the ford intake.

Bottom line, you can't interchange the carbs without changing intakes.

 

I did notice the different bolt pattern, but I thought maybe there was a adapter missing or something. But now I know, so I can junk it. Thank you. Next question that comes to mind is how good is the 94 model carb and what years did they come on or where their to many years to narrow it down.

 

The 8BA carb is roughly 49-51 on cars. Trucks used a 7RT carb from 48-52?

There were literally dozens of varieties. All work about the same and will perform well for you. If that one isn't doing the job, somebody didn't do a thorough rebuild on it.

I had one that ran like crap no matter what I did. I happened to pick up another at a swap meet, bolted it on and it's been running like a champ for the past 10 years.

Never, ever, run one without an inline filter. The screen on the fuel pump doesn't clean the fuel enough. I use NAPA gold 3002 inline just before the pump.

 

Cool, thanks for the info. This one seems to work good. Just trying to narrow down my motor. witch sounds to be a Heinz 57.

 

It was used on the F-7s and F-8s with the large Lincoln y-block as well, only with a governor.

 

This is a "correct" carburetor for a 51-53 that is in the process of being restored/rebuilt. It is cast with 7RT, and was referred to as such when used without a hand throttle lever. It would have a cable operated choke lever (51-53). It was called an 8RT ( cast 7RT) when equipped with a cable operated hand throttle and used the cable bracket pictured.

Your 8BA carburetor will work fine as would an EAB, etc. As long as you have the venturi vacuum port you're fine. If your dash has the provision for a hand throttle, a "late" base from an 8RT would work with an extended throttle shaft, lever, spring, and retainer. If you wanted the hand throttle, don't get a base from an earlier carburetor because it will not have the extra vacuum port needed.

You will have to use the car air cleaner with that airhorn. In the picture you will see a truck airhorn.

 

The bottom carb is correct for '52-53 Mercury. Very little interchanges between it and the Ford carb.
