Hey SCOTI, Thanks for the thoughts!

Yeah, it's a 4 bolt inspection cover. It probably would be fine with 3 bolts, but I worry it would create a rattle that would drive me bonkers! But moving the mount hole shouldn't be too hard. I'd just drill a new hole close to the bellhousing with the cover bolted in then proceed with chopping off a 1/2-3/4" or so.

On the exhaust, the trick here is the collector also sits low relative to the cross member, so it would help with one angle, but the pipe would still need to kick up to get to the hole so it doesn't really help. I'm thinking a custom header builder could angle the collector like a corvette (only not as much) to get a better relationship to the cross member. No Limit recommends mid or short length headers to avoid this very scenario, but I'm stubborn and really want a long tube header. Otherwise I could do something like Ultimate Headers swept back mid-length and be done with it all.
