My 87 4x4 suburban 350cid, a/c. I'm pretty sure that it's a 4 row raidator. My question is that I have a 5 blade fan, and have a extra 7 blade fan that came with my 400 sb. Would it be to my advantage to put this fan on my suburban? Also I have a external cooler for the trans. What do you think? I'm getting it ready for the trip to Piegon Forge. Thanks.
