Hi Guys, for those that have torn down both motors, would a 250R cylinder block fit in the 300 engine ?

I know the coolant inlet is a different shape on the rear of the block, but the question is whether I could use a 250R block bored out to 64mm or possibly 66mm in a 300 engine rebuild ?!

Thanks
