Have to check but don't think there's enough space in that recess for that fitting.
Anyone know the purpose of those 6 tapped holes in the valve covers? Coil brackets?
those are for coil brackets.
Motion Raceworks has some adapters to put a breather line off the valve cover without welding. You drill a hole in the cover, and the adapter sandwiches the cover with o rings. That might work for you. But, I understand not wanting to mess with those covers…
Is it possible to remove the steel lines from the VC's and tap them for NPT?
I'd be concerned that those little ports wouldn't be enough depending on how much boost he intended to run.
3/8" hose was fine for my old car at 5-6 lbs. but became an issue at 10 lbs. then I moved to a single -12AN line which was sufficient to support 14 lbs.
so is the goal 700rwhp, 1000rwhp? I'm running 2 -10ans, and some folks run dual 12s. Those little stock pipes are too small, and I don't know if that spot will fit a -10 direct, and it will mess up the coating. Maybe you can try to use an adaptor for the oil fill, not sure the size.

I was thinking two -10 or -12 bungs welded to the back of the valley plate, ran to either a big single or dual cans.
Easy to do and keeps the hose clutter out of the front of the engine bay.
My current setup uses two -10 AN lines to a single large catch can.
You can just see the can on the front passenger wheel well behind the intake pipe.
***** I am running the -10s to a can in the nose of the car on mine. Both feeds are in the front of the valve covers so they don't gulp in oil sloshing to the back of the engine, at least that's my theory.
Goal is 1000rwhp, eventually. I am leaning towards (2) 10an / 1/2-NPT in the valley cover, but the concern was the fact they wouldn't be at the highest point. Since there's lots of room under the intake plenum, maybe straight NPT fittings and 90s on the hose will raise the exit point a little higher. Might even tack some baffles under the fittings to reduce possible oil splatter into the fittings like John said.
Undecided on coil placement. Car already has IGN-1As mounted on the inner fenderwell. Hmm. But, I also like the clean look of no coils on the engine, especially with those valve covers. Did I ever say I love those valve covers?
Additional engine setback presented a challenge with the TH400 x-member, but I was able to hack up the frame to make room, then box it back in and fab up an x-member using pieces of the stock tranny x-member.
All the accessories are in place for mockup, except the ATI balancer. Using a small case AD230 alternator in the Corvette location and the mockup will be replaced by a Powermaster, 1-wire, 165A unit. Not surprisingly, ended up with trusty truck manifolds.
Did my best McGyver to come with a way to support the 40lb VSR billet 85/102 and have side-side, forward-backward and up-down adjustability to come up with the final resting place.
First order of business is the turbo support with a Maven mount, looking something like this but more of a 90* bend to bring it closer to the frame and with additional support.
Both - i wonder why nobody's done venting thru the valley cover?
OK. On my Mustang I had one on the oil filler neck and another on the valley cover. For the LSX376, I don't want to ruin the valve covers so I will be putting them on the valley cover. (2) 1/2-NPT or 10AN ORB, (whichever has the larger i.d.) to 10AN straight and 10AN 90s. Shouldn't be too much oil splashing around in the valley, so probably won't need any elaborate shielding on the bottom of the cover.
You can't see the fittings on the cover but you can see how I routed the hoses.
I know several guys who've used the valley cover without issue.
I think the only downside may be condensation collecting in the form of that nasty white gel in the valve covers, the gents I mention haven't seen that but that's all I could think of.
Making progress. Turbo support, ATI balancer and alternator done in the Corvette location with a Powermaster small case AD230 and ICT Billet alternator bracket. trying to find a 3" alternator pulley. Started on the manifolds-to-turbo hot side but waiting on a set of 2.25" pie cuts.
