If I remember right, the factory choke wire should be purple and will probably go through an oil pressure switch.

looked through the one book for the wiring diagrams and it says its a blue wire coming from the oil pressure switch like bigredlaguna said. so gonna mess with that over the weekend I think.

also ordered a hood pad and it came in but nothing lines up the way it should. gotta find one that works, got it from the parts place but they said that is what it should be. not sure if Ill make it work or try and find the proper one.       75 el camino project.  - Page 10 Img_2011

so finally got the hood painted. and mounted on the car, just need to align it.

75 el camino project.  - Page 10 Imgp6011
tried a little but already chipped the fender some so took a break. so got a few questions:

lowering the hood is basically a whole ab work out. any advise on how to get it to move smoothly down or how they are supposed to operate. I know you shouldnt need force.

where the hinges mount on the fender should any shims be needed? I have the front clip all lined up:fenders to front facia and light buckets, but the hood seems too wide in the front to fit down

is all the hood adjustment done in the top part of the hinges or is there some done down by the fenders?

how much gap on the sides and front when the hood is down does everyone seem to have?

and finally when the hood is open is there play up and down in the hinges?

Riddick ,

I do not have any pointers for getting the hood on the car. But , with the weight of these...it is a struggle especially when attempting to not chip new paint. I used no shims. All the adjustment is at the rear of the hood. Only thing up front is going to be the height of the hood " bumpers" on the core support adjusted either up/down.
As for he hinges though. There should be no play.

I had mine rebuilt by this guy:

When installing newly painted panels its always a good idea to use masking tape on all edges of the panels you are working with. I lay down 3 layers of tape for added protection. The alignment of the hood is done with both the mounting hardware that bolts to the hood itself as well as the bolts to the inner fenders. The ones on the hood are for lateral adjustment and the ones on the inner fender are for height adjustment near the back of the hood. As far as the stiffness of your hinges go, I would spray them at the pivot points with a good silicone spray and then push each corner of the front of the hood back towards the windshield a little at a time until you get it to close. As you push back, it will inherently want to go down in its closed position. If you can't get them to loosen up are several cycles, then you have the option of buy a good used set (hard to find) or a reproduction set from Goodmark. I've heard mixed things about the reproductions so do some research before you buy if you go that route. Also, some vehicles are almost impossible to get the hood "square" with the fenders and front header as the front header really has no adjustment for width. I have this issue with my Laguna which has a urethane nose. When I get to painting it in the near future I'll have to build up the sides of the front nose to make it slightly wider to match the fenders when they are adjusted square with the hood. I will probably also have to enlarge several of the mounting holes in the fenders/core support/front nose to make it all work. Hope this gives you a better idea of how to move forward on your.

thanks, those are some good ideas, when I didn't have the springs on they seemed to move relatively easy, and the rivets were tight with no slop. it could be that I just need some more lube in there. and after the first chip on the fender I put some painters tape but Ill add some more like you said for safety. so it basically is just fiddly to get the hood to sit right, once I get the joints freed up better it might make things easier.

I had alot off issues with mine ( 75 chevelle.) i Found that mixing years is bad. Like my 73 fenders and 75 hood. My right fender sits perfect, but the left just dont fit wery Well. I can only say it is wise to test fit it all before paint. Also i have noticed that if the hinges are to hard to close, the hood can actually bend if one is not careful. My experience is it is best to start with the doors and work forward one piece at a time. But its very time consuming and can be frustrating. Patience is key. Good luck and beautiful car.

ok so I got the hinges lubed up AND it moves so much easier. so on to the new issue. still trying to allign this damn thing, passenger side is tight in the front light bucket when I pivot it away from the passenger fender. driver side is all the way back, and front of the hood has about a 1/4 inch or better space from the light bucket, also noticed a bend in the hood...typical bend from closing hood, got it that way because this is the first time I had the hood on the hinges, car came with the hood strapped down. also both sides of the back of the hood, don't stay down/level with the fenders. what locks down the rear of the hood from pulling up? there are the two bolts but I never messed with the height and they dont even touch the hood when I push it level.

The hood hinges are adjustable up and down. Just loosen the bolts that attached the hinges to the inner fender. But only loosen them enough so they are still somewhat snug. Then when you get them adjusted correctly you can carefully open the hood and tighten them up without them moving during that process.

Hi. Also make sure there is no play in the rivets in the hinges. Or Else that could be why the hood sits High in the back. Otherwise it helps having a stick to keep the hood, then i loosen the bolts just enough till the hinges start to move. Then tighten them up and see how things look. A little adjustment at a time and patience.

I usually remove the headlight buckets or leave them off till the hood and fenders sit right and Line up. Then i put them on last. My 75 is wery tight in the drivers side hood to bucket. And im guessing they are just that Way. However its made from potmetal and are easy to grind on the edge so it fits better. ( easy to repaint a headlight bucket if need be) also the headlight buckets and front headder seams to want to pul the fenders together, and out of alignment. I fixed mine with shims between headder and bucket and by enlarging the holes in the fenders.

Also the back off the hood can st so low to the windshield, that the drivers side wiperarm grind on the hood moulding. So beware the the fender and hood dont sit to low on the Cowl. If the wiper hits the moulding on the hood when in use. There is only one solution and that is to lift the doors and fender up till it cleares. Again patience and no play in hinges for hood or doors are key. Good luck.

ok messed around more trying to get the hood alligned, my dad came in and we spent about a week trying to get it right, turns out it did matter how I put the body back on, we shoved over the body the best we could (lots of weight and only a few jacks) not perfect but the hood closes better, or rather closes. also got a new distributor because the old one seemed a little tired and the vacuum advance didn't work at all. so now I fired it up and got it base timed at 6 before, runs ok but I hear a knocking, one thought that has been a concern is a rod knock. also when looking around I found the spark wires are burning at the boots from the headers, so it might just be spark leaking out before firing causing the issue. want to start there before tearing into the motor again. so does anyone have a solution to the boots melting from headers? better wires/protection. also I was using https://www.amazon.com/Protect-Thermal-Protection-Insulator-Titanium/dp/B07QZR765H/ref=sr_1_1_sspa?crid=1I7HC0S9132H3&dchild=1&keywords=spark+plug+protect+boot&qid=1620064276&s=automotive&sprefix=protect+a+boot+%2Cautomotive%2C182&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyWk5WRVBHVlBSRVgyJmVuY3J5cHRlZElkPUEwMTcwNTgyMzFBQ09SREFPU0g5OSZlbmNyeXB0ZWRBZElkPUEwMDE3NDQyWEFGVE9CVlBUUlQ2JndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== and they still turned into putty.

Glad to hear you got your hood alignment to a point you can close it. As far as the spark plug boot goes, the high temp boot sleeves you have a link to is what I've used on several vehicles with headers with good results. The next set up is a wire set with ceramic boots. They are expensive but work well. The "rod knock" could be several different things. Could be the spark jumping from the melted boot but that usually is more of a snapping sound. Another thing is the valves could be adjusted too tight and the valve is hitting the top of the piston. One other possibility is that the baffle in the valve cover could be tweaked and is hitting a rocker arm. Had that happen on one of my engines a long while back after changing the valve cover gaskets. Sounded just like a rod knock. What work have you done to your engine? That might help narrow down what the noise is.

the engine is out of a 1981 camaro. it ran before I tore it down. took it to a machine shop to have everything honed and milled. the heads were replaced because the valve seats were cracked. new cam was installed. hydrolic flat tappet lifters, stock intake, new msd distributor. new valve covers. basically a stock motor rebuilt. I did the break in procedure for the cam. i figure I would start with the wires being they are burned, not sure if it was just from the initial burn in or if its a constant thing. when I was poking around with the stethoscope and it sounded like it was on the driver side around 1 or 3, 1 was one of the burned boots. when did valve lash I went 3/4 turn,

The knock sound could be piston slap from the dead cylinder. If it goes away after the wire change, that is probably what it is.

Did you listen for the noise from underneath? A true rod knock will be unmistakable to you when your ears are under the front bumper.

yea I listened all around, even with the stethoscope. I figure I would do the simple fixes first. going to order the accel wires with the ceramic covers. if that don't hold up to the temp I don't know what would.

ok update time, got the new wires, the accell 9000 ones with the ceramic plug boot. gotta say I do like these just for the ease of them clicking on the plug evan at tight spaces by the headers. also put on the titanium wrap about 6 inches where they would be by the headers. 4 of the 8 plugs were melted at the boots. now it fired right up, no knocking sound, a little bit of a miss every so often but that might be due to certain plugs not firing right all that time. guess 4 out of 8 not working makes the engine not happy. I even took it on its first voyage to the gas station. only died twice, with the air cleaner on the idle might be a little too low, did everything with out it on for ease. still gotta mess with the choke, seems to cool down too fast compared to the motor, its an electric on a rochester. just needs a little more tinkering. I also wired the choke off the idle solenoid, off the oil sensor with one terminal it triggered the light on all the time.
