Carburetor Question - Is this a good call?

-
I just went thru this exact thing. Off the shelf Allen head cap screws WILL NOT work with that plate. You need the short head Allen screws. Hard to find locally, fastenal doesn’t stock them either.

also, I found the only adapter to that works is the 4G to Holley adapter sold by Speedway Motors. It lines up perfectly and clears the throttle blades where others , you have to grind the openings to match the intake.

also, do not get the one that has the WCFB pattern, you don’t need it, and those four extra holes will pool gas. And leak. Been there.
I’ll find the link shortly to what I ordered. It was 14.99 off speedway and came with all the studs and bolts and gaskets needed.
 
Thanks Chris.
I can see in the photo that a depth measurement for the screw head is needed.

holy cow! lol. Just touch the top of the head of the bolts off on a grinder... done in 60 seconds with all 4. Done it a bunch of times for a lot of style of adaptors

or there is that. However, while I've done that in the past, almost always, I've managed to screw up the socket for allen key so it rendered them useless to re-use or take off. But I like your thinking.

I guess when you live in a one horse town, and you have to drive for everything or wait for a on-line order, I just don't have the patience. Usually what I have will work or I can make it work.

I hear ya. I'm 20 miles from town one way, so normally I try to do that same thing. That's why I like McMaster carr, if I'm not in a hurry for a nut or bolt, I just order it.

Yup. But if he doesn't have a grinder...
its not like the old days where every parts store had a small shop in the back or downstairs. :(

he may not have a carb buddy, but certainly he has a buddy, next door neighbor, brother, etc that has a grinder.

Heck even in parts of a sprawling city.
Not one parts store left near. And just one hardware store. A little one - packed to the gills - but they don't have things like socket head cap screws.
There is one industrial supply house left - so I shouldn't complain.
But for auto parts, its 20 minutes easy each way to the box stores - further to a real one. And since they don't know me, its two trips for anything they have in stock.
Maybe I got spoiled. The one that was close I could just call on the phone and then go pick it up - usually later that day - depending on when their drivers were going to the warehouse with the parts I needed.

I don't know. Seriously. Around here - I'm about the only one with things like that. In fact I keep most of it at my garage in South Philly so my answer to neighbors is usually no, or yes but you'll have to wait until I'm going to the garage.

Agree. Its a PIA.
At least down by my garage, there's a others doing welding, plumbing, stuff like that and generally help each other if we can. I hate stopping because then I lose track. Takes time to get back up to speed where I last left off.

McMasters is great 'cause they often ship from NJ - which is right across the river. One day delivery regular mail 95% of the time.

well, if the op stays at it, he'll get it and learn a lot in the process. He's already learned to look for alignment carb-adaptor-intake. He'll get it. Then he'll see how easy it was, and next time, he won't need a thread. And that's great, because it means he hurdled that step
 
Dam...This is all so unnecessary. Hardware store, grinding bolts, adapter plates, Mcmaster car drawings, vacuum leaks, gas leaks,Speedway Motors, Allen head cap screws. On and on. It really is mind numbing, and frankly embarrassing how difficult this is being made.

yeah,,,,, easy for us that know, isn't it though?? But he don't know, and he is willing to learn. Always harder to help somebody over the computer than in person. IF I was there, it'd been done in 10 minutes. But I'm not. I know, you wanted him to go grab a eddy..... lots of cooks in the kitchen. LOL. I applaud someone for trying, and he's trying.

I applaud him as well,he is trying. We all had to start somewhere. I really am pulling for him, and hope it works out.

Good to hear someone else has gone through this. I'm surprised Holley doesn't build this themselves.. PS I found a Carter AFB i'll get just to have cause its close and cheap and keep it in plastic in case i say "F THIS" and throw the Holley in the trash.. but if you knew me (and you guys are figuring me out pretty well so far), you'd know this is a puzzle and it MUST be solved. I won't ship it to a shop, and when it fires.. man.. that'll be a car-gasam for sure.

One nice thing about Mcmaster is they often supply drawings if you dig down into the product details.

I work in industries that deal with drawings like this all day long. I love that they supply that - this i can relate to.

this is what I did. Ordered them from McMaster Carr. They were 1/4-20 if I remember right, 3/4 inch long

Hey @dukeboy_318 - did you have to order those screws for the correct plate you linked to above? OR the ones that came with the kit are ok..? once i hit "post reply" i'm calling Speedway and seeing if they can just supply me a set of screws since i already have a plate. BUT like you said.. the holes may hold gas etc.. i'll see what they can do since i already gave them money once.

Yup. and as you can see my stupid Holley has no external sight plugs or otherwise to adjust the floats.. annoyed.

Thanks guys - the learning curve is strong here.. haha.. But after all the help here and the numerous videos and messings with; i feel like i know so much more than before. And @Johnny Dart - i'll shoot you a call this weekend when i can get back on it. I may order the bolts listed above, but I want to check some supply stores nearby my work (which is a very industrial area) before i jump on it (as well as call Speedway).

Happy Monday all.

The one I linked came with the correct ones. I tried multiple other plates, including one from Holley themselves, that did not come with the right screws. Some didn't even come with screws at all.
 
I would call a moratorium on buying any new parts (AFB).
Reason being, jets,rods, tunning parts, are harder to find for Carters. They are different than what is used in Edelbrocks. Stick with an Edelbrock if you decide to go that route.

10-4. It is cheap and OEM so i thought about just snagging it and storing it away..
 
Basically stock engine? if its cheap and a model used on a similar engine, shouldnt be needing to make a the type changes needed for for tuning a hot rodded or race engine.

Yah, totally stock. I've only done the heads to run better on unleaded gas. The car is surprisingly low original mileage (65,000) so I've just left it be.
