I am getting ready to place an order and am needing advice on the 650 Thunder Series carb

I am using the performer RPM intake on a 383 and 727 combo.

The car right now has the original 318 and 2bbl carb.

Is there any special linkage or anything to make this carb work on my '68 b body? Specifically a throttle adapter or for the electric choke?

Thanks

You'll need the mopar specific throttle adapter that bolts up to the side of the existing linkage.

Choke only needs a power source to work on any vehicle.

I'd bet that some of your 2 barrel throttle and kickdown linkage needs replaced with 4 barrel specific linkage too.

I think you can use the OE throttle adapter from the 2bbl, the one w the pin and the nut that screws on/secures it. If you have a functioning heat riser I'd suggest useing an OE thermostatic choke in the well. At least on my eddy 1406 the elec choke comes off way too fast and b 4 that the choke pulloff is inop but haven't dug into it yet. EDIT Roe is right, forgot about that, also need the horsehoe shaped bracket for the pin/nut to bolt into. The one for a holley is slightly different (bolt hole C to C) from the eddy one but I think you can easily redrill the carb linkage hole slightly next to it for a holly one to fit if you happen to have one but those adapters are cheap. O'reilly's or a similar parts house that has an Eddy carb accessories will have it & iirc less than $10

yep eddie sells the mopar throttle adaptor and you use the throttle stud from the 2-v carb to hook the cable and throttle pressure valve linkage up

most times you can lengthen the TPV linkage from intake bell crank to the carb 1.5" or so and bend it around and make the 2-v linkage work

this is important to keep the tranz from burning up and to have the shift points set correctly

when you go from the SB to the BB you will need BB TPV linkage for your yr b-body

I dont thin any of the SB stuff will fit or work for the swap

I sugest you locate these parts before swaping in the BB along with the BB tranz

you shift likage should hook up from SB 727 to BB 727 with maybe some adjustments..IIRC

most important is to have the throttle pressurevalve linkage hooked up and adjusted correctly

thats the most important thing on the auto tranz

Thanks for all the help guys.

Anyone know where to get the BB transmission linkage (TPV?) other than from a parts car?

the Bouchillon cable is another option

the lokar cable is an option but not as good as the Bouchillon one

parts wanted add here on the board

parts car

full manual valve body,linkage not needed..thats the way i went with my 88 440 truck...stock linkage for a truck was pricy

good luck

Here's my 340 with a 1405 600 manuel choke Eddie carb. BTW a manuel choke Eddie is way better for performance than a electric choke model. I would never want one.
This setup(throttle bracket and trans linkage) has been cut on, welded on, modified since the late 70s. It has been used on at least 5 different manifolds over the years. But it give you and idea of what the brackets look like. This one's a driver and I don't worry about cleaning the engine. As long as it don't leak oil, I don't touch it.
It looked the same after running it hard at Bonneville. No oil leaks!

Nitrous trigger equipped.

I don't use a choke cable, although here lately I've been thinking about putting one on...Only because I have driven the car in cold climates, like at the top of Pikes Peak.
I think this is a different manifold in this picture.
These 2 pictures were taken after I drove the crap out of it on the salt in Utah. I disconnected the vacumn advance because I wanted to be sure my motor would be good at hi speed at miles at a time. It lived and going back this year. It went 118 MPH last year not really trying, watch out this year.

I tried this RPM manifold, it was a dog compared to a Victor340 which I currently run.

what is the link chain for?

throttle stop?

NOS micro pull switch for WOT only?

I need to add something like that for when my boy drives my truck

detune it a bit
