Default First day of tinkering with my '70 (updated 9/25)

First order of business was to vacuum out the accumulated 10 years of debris from the engine compartment. I did get the outer parts of the distributor cover but not the center piece.



Some rodents had obviously taken up residence, at least one of the little ba$%#^ds didn't make it; I'd like to think the car closed the wiper compartment on it.

Next up was to take a look at the #2 body mount to see what that part of the birdcage looks like. The car spent most of it's life in Texas, but there were a few years in MI, so I was a little concerned. No need

After a bit of vacuuming

Pulled a front tire to take a quick look there




Wow, gonna need some rotors, was kinda figuring on that anyway, in addition the master cylinder is completely dry. Again, I expected this but never having worked on a vehicle that was left to sit for this long I'm still surprised to see this stuff.
Distributor cap, rotor and points look almost new, going to pull the plugs tomorrow and squirt in some oil, crank by hand, install new plugs. Maybe this weekend in between painting the exterior of the house I can dig out my old custom made pre-oiler, then I'll just hook up a line to my gas can and see what happens. At this point I'd just like to get the engine to fire without dropping the gas tank, lord only knows what is in it.
Haven't worked on a carb in at least 13 years, going to have to crank up the memory banks for this old quadrajet...

Good Luck Russ! Great year to restore. You will find as much help as you need on the forum.

Cheers!

Rotors don't look that bad, actually. They have a lot of surface rust, but that can be brushed off. It's up to you, but a good re-face job will salvage them, if you choose to do so.

Looks like a lot of good mixed in with the bad to me. I would have fun with that, I hope you have more! Save another '70!

I'm no expert, but I'd be happy to provide any assistance I can, as the other '70 owners who have chimed in will. This place is a GREAT resource!

Good to see another 70 being resurected!(Sp?)
I love the bones! Have fun with it!
You may want to do a bit more investigating re; the bird cage. All those rust flakes came from somewhere.

Of course they did, and they likely came from the vertical posts at the #2 mount or the windshield frame. It's a 40 year old car, there is going to be some rust on unprotected steel parts. Nothing I see in the pictures says "rust bucket, run away!", but of course, I could be wrong.

Have you looked up the engine number to see if its still the original 350/300HP? should be CTL,CTD,CTM or CTG

70... cool!

If it were the original engine I'd expect to see the VIN derivative stamped on the ledge.

RE: Rust flakes... not necessarily cause for alarm, more a caution. My guess would be top corners of the windshield frame...

Yes, I did that yesterday also. CTG and the vin does match; 416200 sequence number.

That was my thought from what I've read so far. The windshield is cracked anyway, so how do I get in there to take a look and, hopefully, just POR-15 the offending areas?

If you're replacing your windshield, you'll have a chance to inspect the windshield frame while it's out. That's the only way you'll be able to see what you really have. You can get an idea of waht's there if you remove the trim around the windshield and interior trim (pillar and header covers).

I wouldn't expect to see anything serious if the car spent most of it's life in Texas.

Hi R,
It does look like an interesting project.
It's odd in that some of it looks totally untouched, a few things have been off and not well re-installed, and a few things are missing. Sorta like it's lead 3 different lives.
A 70 certainly is worth the effort!
Regards,
Alan

You gotta love that, flat top pistons, 64cc 186 heads, true 10.25-1 C/R, I put a L82 cam in mine, later closing intake to lower the dynamic C/R, no pinging on 92 pump gas now. While working at a dealership a customer brought his 70 vette in to have his engine replaced with a ZZ4 crate engine. I asked him if he wanted to sell his old engine and ended up buying it for 300$. All it needed was a timing gear set and sent out the 186 heads to have hard exhaust seats installed, used fellpro .015 shim gaskets to get .040 quench and above mentioned camshaft. Not trying to hijack your thread, thought my experience with this motor might help you some.

Don't be in too much of a hurry to get it started. Make sure you do it right so as to prevent damage. For now I would keep cleaning and inspecting to see what you have and what needs to be done to make it safe to drive.

Saving another 70 is a good thing.

Default Update

5 min. here and 10 min. there over the last week and I've uncovered a bit more. I pulled the windshield trim and interior 'A' pillar covers along with the disintegrating weatherstrip on both sides.



Is this hole supposed to be here?



Here's a different view



And the passenger side







Oh, and I pulled the wiper tray cover to finish vacuuming the debris from in there, is this hose supposed to be covered in some sort of black gunk? My suspicion is: no



After the windshield comes out ( the top is already loose all the way across ) I am thinking about pulling the dash to access more of the birdcage, then depending on what I find, simply cleaning everything up really well and putting some POR-15 on it.

I don't remember seeing holes like that when I redid my pillar WS's. I hate to say it, but you could have some serious rot going on. With the wind shield out though, now's the time to fix it.
