On my '64 F-250/292 4spd, someone prior to me has changed the carburetor. I need to replace or rebuild it, but I'm not sure what it is. There are no tags or castings as near as I can tell. So, that leaves me with replacement. While I am a fan of keeping things stock, I have also had good luck with Carter/Edelbrock.

What I am wondering is: What carburetor/intake are you running on your Y-Block, and do you have any other performance products that might have required a larger carb?

You guys are great...

Which intake do you have on it? The 9425-D?

 

I'm not sure... As near as I can tell it's stock, but I haven't noticed any casting #'s. I'll look and get back with you.
I did notice that Jegs has got a 2bbl Holley for about $220 with a manual choke and universal throttle linkage; I'm just not sure if that's a standard mounting pattern or not.

Thanks
Andrew

 

If it's the late 2bbl. intake- should be, if it's original- it should be the pattern that would fit a std. Holley 2bbl., or an Autolite.

 

i just put a holley 600 on my 292

 

I have a 60 F100 with a 292, looking to do the 4 barrel swap. I have a 9425-A intake that I can clean up and use. What carb should I be looking for for a direct replacement? Good times,

cordespc, I'm not sure what you mean by "direct replacement," since the 9425A came on Y Blocks of 1956 and before. If you are looking for something that will bolt on to that manifold, then you need to look for a Holley Teapot or a Carter WCFB with the appropriate bolt pattern.

If you prefer a new carb, or your goal is to have good drivablity without a lot of fiddling around, buy and adapter and get a 390 cfm Holley or a 500 cfm Edelbrock/AFB.

 

Thanks Timmy, love your site by the way. Maybe I should be looking for an edelbrock manifold to make things easier? I will have to scrounge choke and throttle linkage from somewhere else since mine has been "doctored." Thanks again

Paul, for getting by with a lack of fooling around, I'd go with the 57 9425B 4v manifold. They are not too hard to find and some of the later big trucks also came with a similar 4v manifold that will take a modern Holley or Edelbrock/AFB.

That's going to be the easiest, most reliable path.

If you are motivated to tinker and fiddle with carbs, I think you could be fairly successful with the manifold you have and a teapot or WCFB. But you will take awhile scrounging up a good carb at a reasonable price.

If you are set on an aluminum 4v manifold, go with a Blue Thunder. They don't give them away, but that will allow you to use a more modern carb.

If you happen to have a larger carb, like a Holley 600 cfm, use it, rather than buying a new carb of any make. I have successfully used a 670 AFB (same as modern Edelbrock) on a near-stock 272. It worked fine. If you are going to spend money for something new for a fairly stock street driver, then go with the Holley 390 or Edelbrock 500. Both are good units. Pick the one you like, the one you can get cheaper, the one you find easier to work on, the one that looks best to you. Any of these reasons are sufficient for choosing one over the other. Also, you can flip a coin -- that will give you advice as good as any to choose between the two.

Thanks, and have fun.
