Turbo....

Have you considered a remote set-up? those can be pretty neat and tidy.
With your engine already having a higher compression-ratio,you sorta have the bottom-end covered and you can use the longer pressurized return-pipe as a form of charge cooler, or hide it in a Lake-pipe.
Or how about a 2-stage system?
One thing that might be in your slanty's favor, is the actual Force on the top of that 3.4xx" piston when the ignition fires. Whatever psi is there, the actual force would only be 85% of what it would be on a 4incher. I wonder how you could exploit that, with the super-long stroke?
I just want to clear something up that I’ve read a few times. I run a remote mount on my dually, under the bed back where the muffler was originally. I run 3” aluminum tube from the turbo back to the intake. At first with no intercooler. I’ve seen a few company’s claim (and AJ said it here) that the long aluminum tube acts as an intercooler and my experience was the exact opposite. Cruising around off boost the temps would hover about 30 degrees above ambient and on boost I saw as high as 260 deg AIT. I installed a water to air unit and now cruising I see 5 degrees above ambient and on boost (12psi) I have never seen more than 140 degrees and thats usually when I’m towing up a grade staying in boost for a while and the water tank gets heat soaked. The tube acting as an intercooler just doesn’t work. @AJ/FormS what do you mean by a “2 stage system”? Can you explain that a little please.
