I recently purchased a set of NOS BBC Appliance headers for my Biscayne. I had no clue if they would fit but was shocked at how well they fit.

The #5 pipe is the one which can be very close to the PS box. I have a set of very nice headers which were unbranded from eBay. They addressed that area by making a separate bend piece out of the header flange which "cheated" the distance to be closer tot he flange but unfortunately they should inserted the piece a few millimeters deeper so there is still a clearance issue; but just barely. Those eBay headers would likely be perfect if the pipe size wasn't oversized so much.
Do you have a photo with them installed? What diameter pipe was used?

In my rush to test fit them I only took a picture on the passenger side. It fits tighter than the drivers side with PS. I'll post a picture of the passenger side. I wouldn't have had them powder coated if they didn't fit. The motor is going back in this weekend and I'll update with installed pictures. The pipes are 2 1/8.

Here's a couple pics of the passenger side. And one with them coated with cermakote titanium.

NOS is a designation for 'New Old Stock' OEM parts.
GM did not install long tube headers; only exhaust manifolds.
They may be 'old', but not 'stock'.
Just clarification, not criticism.

NOS is for any manufactured part it's not GM only!
It's for anything new that was never used (The term new old stock) You don't think that GM produced every part on every car do you! Yes these are aftermarket but still new old stock!

I disagree. 'NOS' does not apply to old (never used) aftermarket parts.
Real NOS (new old stock) parts are rare and expensive. Why?Because they are never used; still in the OEM box (often). Also, they are always no longer produced (by the OEM). They are usually found in some very old parts inventory.
Oh, 'OEM' is 'original equipment manufacturer'; GM in this forum.
AND, the subject of the topic is a GM (General Motors) product (a Chevy) and this is 'Chevytalk'. It does not take an advanced degree to understand my comment.
Aftermarket parts are aftermarket parts. 'Old' or 'new'.

Those look really nice. The #4 looks like it gets pretty close to the fuel line along the frame rail. Will you shroud or wrap the line in that area or will it be no issue?

A lot of people are now using the term "NOS" for any part that was never installed including aftermaket.
I have seen a few designations of "NOS OEM" to distinguish whether the NOS part was from the original equipment manufacturer, versus not.
However, "NOS" is now a common term for a never installed old part. Times change, terminology does as well.

hey, thats a good fit. If the drivers side fits that well you are home free! I am using a set of Hooker Supercomps, also 2&1/8". Mine is a 4 speed car and to install or remove the driver side I have to remove the Zbar, pull the motor mount bolt and jack the engine up on one side for clearance. I guess Appliance knew what they were doing.

NOS, New Old Stock, doesn't necessarily mean stock as factory installed, it also means stock as stuff on a store room shelf.
"How is your stock of canned goods?", "I received a new stock of ratchet wrenches today", though I prefer the term NIB, or New In Box for non-factory parts.
NOS also has meant Nasty Old Sh!T, because a lot of GM NIB/NOS stuff on dealers shelves were stuff that was defective in some way, and rejected for use on factory produced autos (excess casting flash, stainless trim parts too short, pits in chrome, etc), that was simple sold as replacement parts some years after the model had ceased production.
I remember lots of crappy stuff in new boxes from the Chev parts dealers in the 1970s. I still have some of these pieces, it just wasn't up to showroom floor standards but it was good enuf for Chev to sell it to dealers as replacements parts.

Doug,
These two links says what I always believed true about what the acronym NOS means when applied to classic automobiles. I could list many but decided two was enough.
https://www.drivingline.com/articles/nos-oem-or-r e...
https://www.stevelinden.com/blog/oem-vs-nos-parts
Does that identify the parts condition? No. Time can erode quality of certain materials. If the 'NOS' is accurate, the part is original to the car as it was manufactured.
When discussing classic/vintage cars, there are no NOS aftermarket parts.
Again, I am NOT being critical. So, please do not find offense when none is there.

Why do you care about this post? It's about vintage headers. You want everyone to drink your cool-aid about your interpretation about the NOS term. You're not even acknowledging this post is about old school headers. Seriously troll somewhere else!

Thats crazy, mine is a black '66 Biscayne BBC car and I also have a red '69 Z28 in a two car garage. Also some room for a work bench and my tools. A few questions about your Biscayne. What are the sizes on the Cragars and tires? I'm still running a single pot master cylinder on my car. Is that a power manual brake setup on yours? Did you convert it from manual brakes? How does it perform and where did you source it? Thanks

I have to agree with you. NOS parts are often degraded especially if they have plastic or rubber parts in them. All metal trim pieces have been moved around in boxes for 50-60 years so they are not exactly museum quality pieces.
An old aftermarket part can be referred to as NOS if it is, genuinely, "new old stock". I suppose if you want to be more specific, you could refer to original equipment as "OEM new" and end the debate entirely.

#4 tube is gonna cook that a arm bushing and could cause a fuel problem. i would jacket the fuel line, replace the rubber line with fuel injection hose and add a heat shield for the bushing. i guess you didnt get to burn in the headers before coating them? nice ride.

I had them coated and installed hopefully for the last time. Added some vintage GM 074 aluminum heads to give it that day two look.

I like how they configured the driver side pipes. Test fitting mine one of the tubes is too close to the steering box. The pipe diameter used on mine, IMO, is too large which is part of the reason the pipe is too close. Diameter too large would result in exhaust velocity lower than optimum.
