68 f250 core support question

I recently ordered a new core support for my 68 F250 300. I noticed the new one has a bigger opening for the radiator. I believe i got a big block core support, can I get a new radiator and make it work with the 300? Is the opening for the radiator the only difference?

I recently built a big block FE for my other truck, if I were to put a FE in this is the only difference the motor mounts and bell housing? It has a 4 speed manual,

It is not a big block only. It is a Super Cooling core support with a wider opening. You need a Big Six Super Cooling radiator. For an FE swap from a Six, all you need to do is slide the engine perches to the next whole hole with using new FE motor mount. As the Six uses the SBF bell housing, you will need an FE bell housing.

thank you. I figured it was for a big block. I figured the only difference would be the motor mounts and the bell housing
I have the whole dog house off so I figured I might give it some thought
