Foxy Green Foxbody Build

Not a useless test imo. This is what i was trying to suggest when I said look for "leaks" with intake off. If your oil pan was off you could also see how much oil is flowing out the bottom of the bores. If there's a plug missing you should see or hear it flowing

I'll be honest, when I shut the engine off I hear oil draining back into the pan. I've never heard anything like that on anything before, but I've never had a big ass tin can of an oil pan before either. You tap on it and it rings like a timpani

That's probably normal. But then again, if piss all is getting up top and you hear lots running back for a while then it's likely from the valley. Is there a junction in the oil gallery in the valley with pipe plugs ?
 
Not sure what you mean so here's a pic before I assembled

 
You got me digging through pictures of when I assembled the thing. The lifters got scored just from turning the engine by hand. The bores were fucked from the start. Here's the lifters before the engine was assembled.

That sucks. Machined surfaces rust so quickly, especially when cleaned. You mentioned you were not happy with the bores etc and didn't want to sand them. Did it take effort to get the lifter in ?
 
Nothing rusty, but I specifically remember complaining about the bores feeling "gritty" when sliding the lifters in. I cleaned them, they weren't dirty... but it just felt off. I didn't know enough, called the shortblock builder, the owner told me to run sandpaper through the 85% assembled engine. I told him he's nuts if he thinks I'm going to run sandpaper through the bores with an oil pan installed.

What I've learned in all this is don't be lazy. I didn't want to pull the pan (again) but should have so I could touch up the bores.
 
Thing are looking up for you we are all pulling for you .
After you put it all together with out the intake run the primer on it see how long it take to get oil up top

I can't recall - did you say you cut the initial oil filter open and there was no debris?

I have cut 2 filters open and nothing wild in them. There were couple larger pieces looking like casting flash.

I haven't drained oil or checked filter since finding metal up top. Before I drain this next time I'm going to find a pawn shop and buy a big ass speaker and steal the magnet, drain the oil over the magnet and see exactly wtf ferrous trash comes out
 
Any difference in OD between the new lifters and Comp lifters?
I don't have a lot of confidence in Comp anymore, and I actually have very old Comp solid roller lifters in my engine. They stopped rebuilding them a few years ago, and I'm assuming they import all the new stuff. Would be interesting to try and take apart a few of the old lifters and see if you can find something off with the noisy one.

Not to add to your worries, but I'm wondering if the oil is going through the filter.
I don't know enough about the SBF, can the bypass be left open or is there a way to assemble it incorrectly?
I don't have much confidence in your short block builder...

I have never heard oil drain back in an engine, never....... That is really strange to me, but doesn't mean it's a problem.

You're about to get blocked.

Both plugs are magnetic. Sludgy guessing from zinc content.

Let's just say these comp lifters acted as my $600 piece of sandpaper and the Johnsons slip right in. Let's all pray

always a good feeling when the johnson slips right in a properly prepared hole.

i seen your comment about priming when installing lifters, thats how i do it on chevys. cleans out anything before lifters go in. i will even rotate the engine ass i install to get oil in the lifter and coming out.
