Planning a new 383 build that is now going to be a 400

Hey Brian, what is that line off the back of the portioning valve on my brake system? I goes down under the body then back up and goes to the windshield wiper reservoir, is it some kind of vent?
 
I think this might be a case of some vacume line that got incorrectly connected,
but posting clear detailed pictures and the info on, the make, model and year of the car,
would help me research that for you
 
Well, I would say the same thing, but this is something I haven't touched on the car since I have owned it and it had factory clamps on both ends of the rubber line. Here are two pictures one of the line on the car and the port in the back of the portioning valve. The car is 1976 Chevy Nova Medalist, 305 V8, TH200 trans.
It comes out of the portioning valve through that male fitting to the left and the line goes down under the body. That open end is where the rubber line hooked up.

This is the port on the back of the portioning valve where that line makes connection.

I am not sure Bob.
Can't see your pics real clear on.my phone.
Will look on my Home Computer later tonight.
 
At a guess like Grumpy stated it was routed incorrect.
The 70's GM Cars had a Boatload of Emission vacuum lines.
Likely ran to the Charcoal Canister at one time many Moons Ago.

Hey Guys, did some more on the grille today, I got it finished and ready to paint. I mounted it on the front clip and modified the fastening points with better fasteners. Here is a picture of it mounted to the front clip, what do you guys think do I need to put some wire mesh behind it to stop small particles from getting to the radiator? Any suggestions on what to use for the mesh?

I should have put the tranny cooler back on for some porn, but oh well!

Some pretty decent sized rocks could fly through the gaps in that grille... Maybe something with some strength to it...? I have seen grille specifically designed for that purpose. There's some on my daily driver that the previous owner installed..

Stuff like this can be cut and molded to fit the shape.. I can get this at the local store

Hey guys, have been working on my grille last few days, I am using aluminum screen on the back side. I will paint it black when its totally done, I built a border around it with 1/8 x 1/2 flatbar to secure it. I will finish it tomorrow with paint. I think it will look pretty good. I don't have any pics I will post some tomorrow after I get it painted.
 
Amazing looking, everything looks vertical and horizontal just like it should.....nice work!
 
I start on the bumper today, going to clean up the sheet metal and put on a coat of paint. Then its time to move on to the subframe.

OEM grilles are about 250 bux and are just like mine 40 yrs old and brittle, reproductions are 350 bux, I sat down with the OEM grille took all the measurements, with all the materials and paint I spent about 40 bux and I have a much stronger grille and it only weighs about 25 lbs.
 
its always nice to see someone put some time,thought and effort into restoring a component rather than pitching it in the trash and buying a new replacement component, not only does it allow you to have the car composed of more original parts, it tends to build your skill level and get you more knowledgeable about how the car was and is constructed.
i'd also point out that in many cases finding original replacement or aftermarket parts is not something you have access too, and that with some careful thought, many times you can noticeably improve on the strength, apperance or function, of original components

Well budget was most of it, but I did think of how much stronger it would be in light steel
rather than plastic. I also was thinking about airflow to the radiator, supplying enough airflow to help cool about 500 hp the engine will be producing was also a main concern. I know you probably can't see it well, but the backside of the grille has aluminum screen on it to keep objects out. Really Grumpy, the only part of the grille that is original is the turn signal sockets and the little "Nova" tag on the lower right of the grille. I incorporated the turn signals from the old grille so it would have a similar look.
 
I worked late tonight on the bumper assembly and got almost all of it cleaned and painted. I still have a few clips and bolts to paint, then reassemble it. The last 2 yrs of the 3rd gen Nova and all the 4th gen have a bumper shock system that makes refurbishing the assembly long and tedious, but I got most of it done today. It will be finished tomorrow and I will have pics when its done. There are skirts that fill the gap between the bumper and the body that I am going also paint satin black, there are skirts for the rear bumper that will also get the same satin black. If you look at the front clip there are rubber pieces that hang down below the headlights that I will be taking off to clean and paint also.

Okay Guys, I got the bumper done, I know it doesn't look like much, but that part inside the bumper is what I cleaned and painted. I cleaned up the bumper itself with some Waldo(WD 40), old trick my dad taught me, it was nasty everywhere, shot a coat of waldo all over and started wiping and whallah nice clean pristine bumper. The internals weren't so easy, I had to use a wire brush on my angle grinder, die grinder, and drill motor to clean all the crud and surface rust off to ready it for paint. I think it turned out pretty good. A few pics for all my fans! The skirts for the fender are still drying and I will get a few pics when I put them back on the front clip.

Hey Guys, I did a lot of work today, just woke up after I fell asleep after shower and dinner. I put the front end on jack stands and disassembled the front suspension and steering. I laid them out in my garage in order and spent the next several hours pressure washing, grinding, and buffing off all the crap on the subframe. I now know why GM had all the BS with the UAW workers. Man, the mig welding on the sub frame was nasty. I am not a welder, but I could do it better with my eye closed. I always wondered why my Dad skipped buying any mid 70s GM cars. Anyway, I got the sub frame cleaned up and fogged a light coat of satin black followed by two heavier coats. Man, when I came in the house I looked like a West Virginia Coal Miner before I showered. I will start on the suspension and steering parts tomorrow and start painting them. Here are a few pics of the sub frame and parts.

Since it hasn't been long since I rebuilt the suspension and steering it wasn't real hard to pop them apart with no problems.
 
I will get all the parts done and let the subframe dry and cure and then I will pressure wash the firewall and get it all clean and ready for paint.
