4 core rad

[chisler]

Going to replace the rad in my 72 k10 with a 4 core (big block rad), i already have bought the larger supports/rubbers which cradle this rad,is this all i have to do......looks like out with the old..... In with the new...... Starting to get pin holes in the side tanks on the original and i think its going to fall apart once it gets hot tanked.then i most likely would be looking at a new rad any ways truck has the orginal 350 but will be replaced with a 400 sbc ,just wanting to know if there is something else that needs to be done, shroud etc, should be a good up grade, always looking for the experts advice thanks
