So we put some magnum heads on an la 318 that we stroked out. With that we decided to adapt the factory kickdown linkage. I'll post some pictures of it in a bit
2 barrel carb to 4 barrel carb linkage

Basically just bent the mounting tabs straight. If this was done with an la style intake I would think you would have to extend it a bit to get it to line up.

I haven't set the kickdown yet with the bolt but holding it with my fingers it pushed the valve all the way back at wide open throttle.
Yep, 2bbl linkage works just fine in most applications when installing a 4bbl. Good work!

i bent my 2bbl linkage to work with my 4bbl but the clamp on the throttle cable bracket does not clamp on the metal sleeve. cable istoo short and does not have enough diameter to clamp on the plastic sheathing.
can i just wrap tape around it to secure or is there a better way to clamp it that ya'll know about.

Don't hate me because i'm beautiful
Personally, I would modify the bracket so that it camps on the metal sleeve.
If the throttle cable isn't supported (clamped) properly, it could bind the cable and cause an unsafe condition where your throttle sticks open.
Do it ASAP!

ok thanks, guess i will bypass the cutting and welding and just buy the proper bracket from brewers. much easier to throw 50 bucks at it than spend time on it redesigning it and metalworking it. mo money mo money haha

You could make a 1" link that would attach to your carb and then the other end wo ik ls attach to the end of your throttle cable. That would put the metal sleeve back where it should be to clamp in the bracket

just add a spacer from the carb to the end of the cable..... you can see it on this carb set up
And.....

Wow...Just Wow.
All the correct parts are available for less than $100.
Why go through all the trouble and money to stroke out a motor, only to get chincy on the little things. Where's the shake my head button ?

Looks fine to me. I'd have probably slid the cable up to eliminate 1 link, but should work fine. Two throttle springs of course. Yours is a stick shift I assume? I don't see kickdown linkage..

i guess when you spend 4 dollars that you really dont have you will understand why i went this route. i am tapped out on building this from bare sheet metal and i am just trying to get it running at this point.
yes 4 speed
thats as short as i can go unfortunately. have less tha 1/4 inch to slide it up closer
IF they made "chain links" for this conversion, most would recommend it for price and simplicity. But for heaven's sake, don't use any ingenuity yourself... LOL.i guess when you spend 4 dollars that you really dont have you will understand why i went this route. i am tapped out on building this from bare sheet metal and i am just trying to get it running at this point.

If you have the 2bbl bracket, the cable won't reach without extending the end like he showed.

Google 340 throttle return spring.

i did GOOGLE it before i asked and your particular ones with the dual springs and longer striaght section on one side dont show up. thats why i asked where you bought them from. as far as i have researched the 340 return spring was a singular spring from the factory. i am wanting to go with a dual spring setup. like the one pictured above. if thats not you engine pictured above. my apologies.
