I am stuffing a GM 3800 SC into a 1987 Fiero GT and I will make the assumption the radiator for the little 6 that was in there just isn't going to be good enough. I looked over the area for a radiator and boy, there are not a lot of options. I'm thinking I'm going to have to do away with the AC radiator to maybe make room for a thicker one? How are you pro's handling the additional cooling needs of the 3800SC?
If you do decide to replace the radiator for any reason I have had good success with the Champion three core radiator. There is one currently installed onf my car with a 3800 SC Series III engine but I replaced the old stock radiator only after a collision with a hog one night on the way to a show.
The stock radiator in good condition will cool a 3800SC without any problems. I changed it to a Champion three core only because I run an automatic. The Champion 3 core heat dissipation quality is better and the trans cooler on that radiator is larger.

that is exactly what I am going to replace it with. Too bad about the hog....
I was finding pieces of that damn hog for about the next four months. At least there was no body damage due ti the way the car rolled up on the hog. However, I did really shave the hog quite well. The car also won Best in Class at the show and I was quite pleased with everything but air shipping the new radiator and having to pay someone to install it since I had no tools available in the vehicle.
