Just looking it appears to me that the transmission lines are kinda in the right place. The width is roughly same. Appears to be 2 " taller which may be an issue. But hose sizes are wrong for a small-block and the lower hose attachment is a lot higher-may not work without a weird hose? As inexpensive as radiators are for these, I would just buy one or fix what you have unless you swap the LS engine with it. Again all of this is an opinion based on looking at online pictures not actual experience.
