‘73 Duster /6 to 318 Swap

Ratty73Duster said
Hi everyone,

So, I’ve got a ‘73 Duster with a 225 /6 and 904 trans. I’m going to look at a nice 318 LA tomorrow and I’m planning on sticking a 727 in place of the 904. From what I’ve read, the Schumacher swap mounts are the easiest route, and require the least amount of work to the K-frame.

Would it be better to just find a v8 K-frame, opposed to using the Schumacher mounts? Also, what all would it take to convert the factory column shift auto 904 to a 727 floor shift? Any major modifications to accommodate a floor shifter?

This is a kind of learn-as-I-go project, so it’s a bit ambitious. Any help would be appreciated!

I would plan on finding a V8 K frame. Schumacher mounts are GREAT but there's something going on with the guy and his business and he's been WAY WAY behind in stock. Almost everything he was making is sold out and on back order and has been for well over a year or more now.

If you go the V8 k frame route, make sure you grab the pitman arm that attaches to the V8 K, the slant ones are different. Otherwise, everything else will bolt in just fine. You may want to see what rear axle is in your duster. If its the 7.25, you'll need to upgrade it to at least an 8.25 as the 318 will likely break the 7.25 if you get hard on it.
