My opinion only, maybe not the post you're hoping to hear...

I didn't weigh them when I swapped. but my opinion is the difference in weight is nothing any of us would ever notice. I mean, you could toss them both in the air pretty easily. A tiny fraction of the weight of the car.

However, I suppose it's possible a 4 core radiator might hold more coolant, and therefore might add a little weight, but again, negligible.

I was wishy-washy about changing mine, weighing the pros and cons, and eventually decided if people like Marc Haibeck recommends the Dewitt, might as well do it and (hopefully) solve all cooling issues and never worry about it again.

I will say, though, that even though the Dewitt is considered a "drop in", it still required some extra work to get it in. I'll elaborate if you want to hear.
