People you CANNOT run a 94 type carb. on a 35-36 intake manifold that has an open hole inbetween the 2 front studs of the manifold. This is a heat passage and you will blow out the power valve if you use a 94 carb on a said manifold.You need to close up this hole,change to a Stromberg carb or change manifold to one w/o the hole ei [later w/o the hole in it]. I have a few guys that are having this trouble.They have the wrong combanation of parts. ken ct.
 
Ken-

Good advice, but how common are '35-'36 manifolds with this heat passage? I checked three '35-'36 intakes I have and none of them have this hole. I am positive they are '35-'36 intakes. They all are aluminum with the raised generator ramp. One I took directly off of a '36 engine.

Ken-

I believe this is the intake you were referring to with the open hole. What is the best way to plug the hole; thread it and install an Allen screw as a plug?

I would say so if you got enough meat there to get 2-3 full threads or you could cut a quarter size or even a nickel size of thin sheet copper or SS to at least cover the hole [shim stock ,004-.maybe .008. use a strom carb gasket with no hole their and put gasket on top of it. It will sink into the gasket and seal the hole. Or use a Stromberg carb ,the open hole wont bother it Only its a problem when trying to use a 94 on a manifold made for a Strom. ken ct.
 
Ken, this is the first time I've read of this info and I see it to be very helpful. Thanks.... Its brought me to question though..... I've just rebuilt a 49 flathead that had a ford94 carb on it that was seriously froze up all over. I just heard thru the grape vine that Santa has put me a stromberg 97 under the tree and I'd like to know if I should expect any issues ? Again thanks for sharing your knowledge . ........ Bob
 
Yes you will have big issues,have Santa send it back [no vac. connection on rear of a 97] Where would you hook up the vacume line to the dist. You need a 94 # 8BA carb from a 49-51. I have them rebuilt ready to go. ken ct.
 
A lot of people block the heat risers in the block. If that is the case I think running a 94 on one of these manifolds wouldn't be a problem. I find the cast iron stock manifolds are easy to find so if you wanted to run a 94 it shouldn't be too hard to find one without a hole.

For any Grits reading this, the most common Ford Pilot manifold has this hole aswell.
That should read Brits, not grits, I just had grits and my brain slipped.

Does eating grits work kinda like when checkens eat gravel? I guess grits and bangers works even better, huh? :eek:

Interesting you mention that, the 221 I'm using came from a Pilot, I'd mentioned the carb (7RT) and was directed to "94" carbs...is the 7RT a 94 variant?
 
Yes,7RT is a 46-47 truck. Has a diff top than a pass car top. Only a truck air cleaner will fit on it. ken ct. Yea its still a 94 type carb.
