The Sweptlines were built with slant 6s in them, there is a bit of room front to back. Then there is a lot of radiator support not used with the 26" wide radiators and space taken up by batteries that the Cummings doesn't occupy. There should be plenty of space under that hood to get enough air flow to cool an intercooler. I've seen things a lot bigger then that Cummings in a lot smaller space that that Sweptline has under the hood without cooling issues. Sometimes a person needs to do a bit of planning. Gene
