I wasn’t aware that Oddfire 231’s existed, but based on what I’ve read, the 231 was a reworking of the 225 with Buick 350 V-8 parts, resulting in the 231’s large displacement. In 1977, Buick introduced the first even fire 231.

    Yep. Jeep sold the tooling back to Buick and they punched it out to 231. Came out in ’75 as I recall. Late ’77 or ’78 they figured out how to make them even fire with a split throw crank, I think. I run an OF 231 in my ’71 cj5. The 225 had a higher compression ratio than the 231. Wish I had my 225 back.

    I had a 225 that was bored (can’t remember how much) with specially ground cam. That was such a great engine. It had a sound all it’s own. It’s only problem was oil issues, which like led to it’s death one day while my buddy was driving it.
