I have a 225 odd fire in mine , came stock. They are torquey little motors. Compared to the 258 I had in my 73 cj5. The one draw back is , a lot of mechanics haven't worked on them, so unless you're doing your own work, that can be a challenge. Plus sometimes it can be a little more work getting parts for them. HEI makes a world of difference, instead of points, also. Good luck, to you, and enjoy.
