I don't know what the specs are on an OZ 250 starter motor and haven't seen one to know if it will work for sure or not. My best guess is that it could if it was for the right trans. But I do know on the Ford US engines there are two different starter offsets 3/8 or 3/4 inch used. Basically this depends on if the trans is going to be used with a flywheel and manual trans or a flex plate with an automatic trans. You can't use a stock SBF V8 flywheel on a 250 six, without a rebalance! SBF V8's can have an imbalance of 28 oz. or 50 oz. depending on the year. A 250 six needs a flywheel with a zero imbalance, there are some aftermarket V8 flywheels that have a removeable balance weight that without is a zero balance. In addistional there are a few different flywheel tooth counts too, the flywheel needs to be the correct diameter for the size of bell housing you plan on using. Good luck
