Again, I am no expert what so ever. I have a F-body rad with a believe an LT1 Fan setup. Here is a picture I pulled from the web of LT1 fans mounted. They really arent that deep in my opinion. But again, I am new to Buicks.
I just installed a set of 2001 intrepid fans yesterday. They are slim, more so than the LT1 setup picture above. Picked up at autozone for $160. So far im happy with them
