I have a 68 Charger with 440. I wanted a bigger rad to help with a cooling issue as the research point to that. I got a Champion aluminum with a 2.5” three tube core.
Here’s the skinny on it. It’s a beautiful looking rad and I like the black better than the aluminum look. However, there were a couple figment issues. The top slot on each side for the bolt are dimensionally wrong. I had to make both slots longer towards the inside to get both bolts in. The rad slides over the bottom bolts by means of an inverted U in the mounting framework. With both top bolts in and the bottom driver side bolt in place the passenger side lower bolt hole is blocked by the outer side of the U.
The angle iron (I know, it’s aluminum) that forms the mounting framework is too long on the passenger side and hit on a “shelf” below the washer bottle. I had to cut 1/2” off to let the rad go low enough for bolt holes to line up.
The rad shroud stands well away from the rad because the channel that it bolts to is set away from the rad core. This looks not good and the fan is now very deep in the shroud. I hope that’s not an issue. A closer channel and shorter shroud bolts, so they don’t contact the core, would be a better fitment.






Yeah, I modified the crap out of my Champion and the fan shroud to make it fit. It works though
@PurpleBeeper Did you get the shroud to fit closer? I’m thinking of having a piece made to close off that opening.
Having the fan deep inside the shroud will likely hurt the performance. Supposed to be centered on the back edge.
Ya I know. That concerns a bit. Might try to figure out a way to mcgiver the shroud closer to the rad.
