whiteflash

So just tossing around ideas here but I recently bought another 6.4l hemi because I need my charger decided to drop a valve but I’m rebuilding that motor to keep the matching numbers but was wondering how hard and what modifications I’d have to do to swap the other extra 392 into my c250 I know there’s a big list of things to actually do the swap but will I have any clearance issues or need to fabricate anything to fit the swap
