Alright. With the original deal for a replacement 225 falling through, I was offered a smooth running 198 out of a '72 Dart. Seller removed motor along with smooth shifting tranny all in one piece. Plus, the price was something I simply couldn't turn down considering the current state of my wallet.

Since I am still educating myself on the world of the Slant 6 I have some questions that may seem simple to some. But, I've quickly learned that this place has some rather reliable sources of info.

Is it a direct swap in pulling my injured 225 and installing the 198?

While I'm not looking to invest too much inthe 198, I am interested in rebuilding the 225 for a reswap sometime down the road. Does someone have a link to a rebuild that will give me increased performance while keeping the reliability that I love so much about the 225?

Thanks in advance.

They will swap... no problem at all, externally they are identical

Check the motor mounts, oil pan and pickup. They may be different depending on what chassis you are installing it in.

The 198 won't present any more challenge than a same-year 225. The blocks are the same, and all the interfaces are the same. Having a matching transmission helps.
I know there were some variations in the tailshafts of 904's, but I don't know the year or model breaks. That might require some adaptation around the transmission mounts.

Grab the 198 even if your not going to use it. Those rods are getting harder to find.
