You really should be fine.
This happened to me on my way to Atlanta and it blocked most of my radiator and i saw my temps rise. I had to pull over and remove it. This is like the worse case scenario as to why your running higher temps.
I drove from Central Florida to North Caroline with no temp problems and others have made further drives. I really don't think you will have any cooling issues unless you have a lead foot the entire trip.
@Rorok is an awesome person who is very generous. He could have easily just try to sell the V3 but instead wants to hopefully give it to a member who doesn't have one. This is what this community is about.
Whalecum to MSO!!! Sorry to hear about your situation. I noticed you live in Central Florida. There are several Members that live in that area that might be able to help you.
There is a local that moved in a few houses down from me and he is installing a few parts on his car tomorrow as well, hahaha. Two house and two little install meets, lol.
