225/231 v6 question

[Dayle]

Okay guys, need a v6 expert. I know little about these engines. Is a 231 oddfire just a 225 bored out? I look for rebuild kits and can not find any thing. Just bought a old CJ3b with a froze up 1974 oddfire 231 in it. I know it will need rebuild. They talk about the 50lbs flywheel the 225 has, would a 231 oddfire have the same heavy flywheel? Where to find rebuild kits and will most machine shops work on this? Any help? thanks Dayle

 

[Out of my mind CJ5]

as far as i remember the flywheels will not swap, and the 225 came with a 75 or 100 pound flywheel, ill have to check on the driierences in the sizes tho i do believe they are not the same thing
