radiator swap question

[michael bustamante]

so after doing my LS swap ( haven't started up the motor yet) I was able to hook up the 4 core radiator I already had ( from my SBC) to the LS hoses. ugly but they worked. upper on passenger side lower on the driver. this radiator has the port on the diver side to hook up the vapor line as well. I went to a shop the other day that recommended me to use a cross flow radiator, where the holes are on the same side because LS motors don t cool well with the one I have now. is this a known fact or was he trying to get me to buy his 400$ radiator?
