1973 Dart Swinger trans.

[erafuse]

Have a 1973 Dart Swinger 318,Auto. Thinking about putting an intake of a 340 on it. What do I have to do to make sure it is set up right for the transmission? I know the transmission is not as strong as what would be on a 340.

Keep the 904. You will be fine. Save your money.

I think he is asking about the kickdown linkage.
What do you have now? Is it one piece or three piece?

Two barrel on the 318?

You will need to get the 4 bbl throttle bracket and then lengthen the kick down rod that goes to the carb about 1 1/2"...

One of our members did a nice thread on converting a 318 2 bbl to a 4 bbl... 6pk2goDemon can you post a link to your thread, I can't find it...

Thanks for the info. It is a 318 2 barrel going to a 4 barrel and its the info on the kickdown I am looking for. I had a 1973 Dart Swinger years ago and had problems with the transmission when I did this. Did a lot of racing with the car back then but don’t plan on racing this one.

Here are a few write-ups about replacing a 2bbl with a 4bbl on a 318:

And one on a 4bbl kickdown rod:

Go with a cable TP control.

Lokar?

Thanks will be using a stock 340 intake and stock Carter thermoquad carb.

Lokar?

That's one, but it's also the most expensive one.
I run an aftermarket cable not made by lokar on my A500 that works just fine.

It sure simplifies that whole problem of steel rods and pivot points geometry.
