I have a Jeep CJ5 that i'm putting a BBC in. it will see limited street use but i'm also going to use it for sand dragracing and offroad.
The radiator measures 18.1/2" on the width and 19.1/2" on the height.
The radiator is 3 core and i'm not sure what it's from.
I think there's not a room for a shroud, but i'm not sure, I can't run puller fan because the water pump nose is just 1.1/2"-2" from the radiator.
The jeep had a Mild SBC with mechanical fan and std water pump and it never had any over heating issues...
This is with small block and as you can see there's not much space for a puller fan !!!!
