He may want to try out a single plane intake & different thickness spacers, the information so far looks exceptional. If it were mine, that's what I would do. And the reason I mention this is, I spent many weekends changing intakes & spacers before I hit on the combination my 408 liked. Now I'm starting at square one with my 416 when it's completed & installed.
I don't know where Garry is going with this one. If it runs consistent he might leave it as is. He figured out why the trans brake wasn't working, blown fuse. Easy fix as long as there isn't a problem there.
