Looks like the air cleaner may just miss.
I could use a thicker base gasket, but the hood will hit. I will just keep an eye on it and see.

Yes. Inside, just like GM.

This is a Letric limited harness, but same deal.

Maybe. Good idea. The issue I always have with air cleaners is trying them out, then exchange, repeat.
Worse than fan belts.
Nobody has drawings and specs anymore.

I appreciate the search and thought. I measured again, and if it's clocked close enough, I think it will squeeze by for now.
I will flag your post. I really want this car done and out this weekend. I have 5 more cars lined up.

I used one of these before on my '77 when I was running and Edelbrock carburetor and intake.

It worked fine for me.

So yesterday, I went to work on plug wires, and got a call for free breakfast. Who turns that down?
Came home, and ran the plug wires. They WERE underneath, so I bought a stock Vette Taylor set.

Numbered them up on the bench, a dab of silicone grease in each plug boot, and laced them up underneath.

I ran them underneath, but I did not like it. So, I pulled them up and ran over. I did not like that.
I ran the front bank over, and the rear under,and I did not like that either.
So, I re ran them underneath, switched a couple , and shortened two.
# 6 sucked, so when I shortened it up, I sleeved it.
Break time.
I come out an hour later, did a fast check, and started it up. Pop out the carb. I am off a few, but not enough. Get it started, same ****. WTF?
I forgot to plug on #6.
Okay, should be fine. Started up, but it runs iffy, like its lean.
Now, I ran it fine before, because I only change one thing at a time. It ran fine as set, so now what?
I decide to call it a day, and when I shut it off, the headlights open up.
Now I know. The backfire blew the headlight hoses off under the dash.

So, today, I know what calamity of events caused what.
I capped off all the vacuum, reset the choke to try another postion, plugged in the vacuum advance, pump the gas once, and varoom.
Instant start and smooth idle.
Tweek timing 2 degrees, and she is happy.
36* at 2800 rpm, 18* at idle. Add vc, and I get 28* at idle after start, and 46* at cruise.

The batt post at top makes a light easy.
If it was mine, I would also jump the purple wire on a button here to bump the starter over.

Now the ammeter , as I suspected with the lower value shunt barely moves, but I never noticed till now it is stuck on charge 10 , even when off or battery disconnected. So, a voltmeter is the answer. I need to pull the dash, as he supplied a quartz clock I said I would install, so I will get one if the owner wants. I think I may keep it another week, as I have a few more things going on.

My ammeter was the same way when I first got my '73. Can't remember what I did to fix it but something in the movement was wrong. Maybe it was just gunked up. Can't remember. I do remember also finding the coil had a break in it. I soldered that back together, fixed whatever was wrong with the movement and it worked fine after that. I later upgraded to Autometer gauges. I've decided I like a voltmeter much better.

These are old Hooker headers. They did make wire holders that work well with them, and I have a set, but in a Vette, they act like weenie cookers.

Default Vacuum

Today I want to go thru the vacuum systems.
I have RobinAir gauges and a HF vacuum pump for A/C work, but I did modify it for this use.
It comes with a freon type schrader port, and to change it, you have to remove the handle and switch cover.
A brass 90* 3/8" npt solved that.
With a variety of 3/8" x barb fittings, your good to go.

Right off the bat, the booster grommet is hissing. I will pull this apart, try some silicone grease. It is a fairly good amount of leakage.

Of course its cracked.
Off to the parts store.
Be VERY carefull when installing. If it falls inside, shut the door and go in the house, and pour a drink.

$5, and fixed. The hose was also a few milimeters too large, so I installed a worm drive clamp.
Now it holds vacuum.
On to headlights.
Much easier like this with the engine off.
Almost always the bypass valve hisses.
Tough to find with engine noise.
