No, not at all actually. I had to cut the "tabs" off of the dual fans just to get it to squeeze down there, and even then, the whole assembly is wider than the core of the F-Body radiator. I ended up having to fab up a bracket to the top of the fan assembly to hold it into place. Even then, it sits about a 1/2" away from the core. Kinda hard to explain, but if you send me a PM reminding me to take pictures, I will post them up.
Also, no the transmission lines will not connect to the radiator. I just have my tranny hard lines going directly to an external cooler.
One other note: When the fans kick on, they have a tendency to draw a lot of current and will drag the motor down for a second or two even if all the wiring and grounds are good. I even installed that little
relay delay module from Casper's that delays the second relay for about 3/4 of a second but it didn't help much. Kind of annoying if you ask me. The fans do move a lot of air though!
