Radiator ?
 

I'm looking at putting a 4-Core big block radiator in my truck. Will it work with a small block or will I need to make some changes? Should I use the Big block fan shroud or the small block?

You will need to change the rad mounts ( 4 core) for the radiator and mount your shroud to that radiator, the small block one is fine, I think the big block shroud is for the larger fan which you don't need to change.

get the mounts from that truck if you can and use them and id keep the sb shroud

I think the shroud mounts to the radiator supports on top. So I’m thinking your shroud won’t work with the larger radiator. Can someone confirm this?
