Stock carb to Holley 94 swap

Post #1 by Tattookyle76 » Thu Apr 12, 2018 6:57 pm

The tomco carb I bought is junk and was a mistake for my 200. Is it possible to find an adapter to put a Holley 94 on? I have a few 94’s sitting around.

Or if I’m going to get an Autolite which one do I need? The car has a pertronix dizzy and is an automatic trans.

Don't know of any adapters for this application so if you wanted to run a Holley 94 on your 200 then you will need to eigher make your own or have an adapter made. On the brighter side though I have seen a pair of these three bolt mount Strombreg / Holley carb's installed on a 170 or 200 log head on a vintage type drag car. Good luck :thumbup: :nod:

Howdy Kyle and All:

If you're serious, an Autolite 1100 from a '65 autolite 1100 for a compatible carb for your LoM distributor with the PetroniX. THe '65 autolite 200 is rated at 185 cfm for a nice increase over your stock carb.

The Holley 94s have a nice nostalgic ring, but no adaptors are available and they are quite tall.

Good Luck.

Adios, David

Do I need the spark module if I’m running the pertronix?

Yes for sure if you still have the stock Load O Matic Distribitor! Sorry, but even though a Pertonix has been instaled in an LOD Distributor that absolutely won't change how the unique advance system of the LOD operates and the need for a matching carb with a SCV (Spark Control Valve) for its proper operation. You can read all about how the LOD system is suppose to work and the parts required to do so in the very good article in our tech archives (see the below link). Good luck :thumbup: :nod:

that's not where that relationship lies.
Please get a copy of "the Handbook" (Matt at VI hasa copy woitin 4 U) & while waiting for delivery peruse the above 'Tech Archive'. Click on the big blue box, scroll dwn to Load-O-M. in the 'Ignition' topic. Heck, read the whole thing. It got me up to speed so now I can ask the right Qs.

What would cause gas to pour out of the top area of the carb where the silver aluminum plug is? That little cap popped off and gas is just dumping everywhere. It’s a new carb.

So I believe what I’m talking about is the vent tube. Has a rod with a spring that moves in and out. Gas will just pour out of here.

Ok then sounds like it's an Autolite carb. Anyway if fuel is coming out of that vent tube then there are only a few causes for that. First would be if the float has stuck you can gently tap on the carb top with a soft hammer or screwdriver handle to see if it frees it. Then would be if some dirt or crude has goten on or between the Needle or seat so that the float isn't shuting the fuel flow off. Next would be if the float level setting isn't correct i.e. It's set way too high. Next is that the needle and seat are defective or damaged. Lastly could be caused from a bad float i.e. It's to heavy and is sinking to the bottom of the fuel bowl. In all these cases except for the first the carb's top needs to come off to check these issues out. If the carb rebuilder gave you a warntee on the carb you want to check with them first before you disassemble it as most times this will void the warrantee. If their isn't any warrantee then carefully disassemble the carb top for a good look inside. Good luck :thumbup: :nod:
