I replaced a damaged radiator on my magnuson supercharged SS. I assume that performing this job on am LT4 is very similar. It's been years, and I don't remember all of the details, but i do remember that I was able to work around the a/c. As far as radiator jobs go, it was certainly more involved than most, but not terrible. I managed to swap mine one evening after work, so probably around 3-4 hours

Thanks. Yeah, that seems consistent with what the manual says. I ended up taking the car to the dealership. They seem to like me there. I will probably get banged out to some extent, but not raw dogg.

I ordered the replacement radiator and will drop it off for them in the AM. So it should just be labor plus any lines, hoses, O-rings if any, etc.
