New-to-me 1968 base Camaro 250 with 20k original miles

About 2 years ago I had a 1998 BMW M Roadster. Well... we had a kid and my wife wanted a new car so I got her old IS250, she took the BMW and a Jeep WJ to trade in and got a mini countryman. Part of the "deal" with my wife was that I would get a new toy at some point down the road. Well I've been looking for said toy for a long time.

Pics of said roadster that is long gone but not forgotten:






Anyway the original thought was I would get a cheaper project car like a karmann ghia and fix it, sell it, and move up the chain. Eventually the goal was to get a 1967-69 camaro.

Well since we just paid off everything but the house and her mini I'm skipping all the intermediate steps and just buying a 1968 Camaro. Picked it up on Friday night!













There's some more in the album here: http://imgur.com/a/yWWpJ

It's a base model with the 250 l6 engine complete with drum brakes, 2-speed auto trans, stock everything, and only 20,000 ORIGINAL miles. Two owners had it before me. It's slow, it doesn't stop well and handling is only OK.

That said it is absolutely flawless. No rust anywhere. Not even surface rust on the frame. It had a rotissery resto in the 1990's and sat in a garage every day. The only rain it's seen has been over the last 6 weeks while it was being sold and even then it hasn't driven in the rain since the 1970's.

I already ordered 3 point seat belts and power front disc brakes. I look forward to many years on this site and hope to gain some brains from you guys who have been around a lot longer.

Plans for the car: 350 swap with TH350 tranny, minor interior stuff, etc.

On thing I did notice right off the bat is that the gas gauge isn't working. It moves slightly when I start it but it's pointed completely to the right (the hand is level with the ground). Any hints on what to do about this?

Also the spare tire seems to have the original paint on it: a slightly darker blue than what's on the car now. Is that the original color?

Anti-freeze: how do I determine what level it should be at? should it be full in the radiator or down a bit? It's about 4-5" down in the radiator right now. What kind of antifreeze?

Transmission: It's only the powerglide 2-speed right now but when it downshifts during deceleration it clunks when cold. Normal?

Regardless I drove it home and then out for dinner on Saturday. Seems to drive pretty well all things considered. A bit floaty but it is 44 years old. Looks like the subframe bushings are shot underneath it. Does that affect handling?

Seeing how they keep the subframe aligned relative to the rest of the car, yes, I'd say they'd have an effect on the handling of the car- the subframe (and hence the rest of the front end that it's holding in place) is slopping around. You've probably got other front suspension parts that need attention as well, even though they've only got 20k on them.

Looks like a really solid car, btw- congrats.

Thanks and thanks!

I thought that would be the case. It's a job that'll get tackled this spring. Since I plan on keeping it for a long time and I do enjoy the occasional corner I'll probably opt for poly bushings.

Nice car. Very similar to mine. In the process of doing a 350 conversion now.

Checking out your build thread: they could have been brothers except for the year. Does yours have the delux interior?

Very cool George... If you are doing a tranny swap spend a bit more and get an AOD (700r4 or 200-4r) and rear gears between 3.42 - 3.73:1 so you can really enjoy all aspects of use in your 1st gen...

As for the radiator, open the cap and fill it so the core is covered; about 2" down from full and you'll not have issues with spewing unless there are overheating problems.

Re: New-to-me 1968 base camaro 250 with 20k original miles

Congratulations, George.
Nice correct year Camaro. a keeper for sure.
You might check the condition of the vacuum modulator by sucking, or applying a vacuum via hand pump, on the hose ensuring the diaphram is not torn.
If no vacuum can be obtained, replace the vac modulator.
Also, check the hoses at both ends of the hard line. If you suspect their condition, replace them.
On the fuel gauge, you may want to check the ground connection on pass side strap, maybe remove it, wire brush the body and terminal, apply soen grease, and reconnect. Maybe jiggle the slip-on connector on the sending unit.
When you replace the body bushings, do one side at a time. Lube threads from above the caged nut with penetrating fluid.
When the bolt stops unscrewing, stop, spray threads with p/fluid, screw in the bolt, then unscrew the bolt till it stops. Repeat the above as necessary until the bolt is totally removed.
When installing the bolts after the new bushings, spread antiseize on the threads of both the bolt and nut. You'll appreciate later in life. You only need an 1/8 inch of clearance to R&R the top bushing. might consider solid bushings. You won't lose any 'isolation.'

Re: New-to-me 1968 base camaro 250 with 20k original miles

Whoa, whoa, whoa.. slow it down a bit there!

I'm a whiz when it comes to new cars but I know little to nothing about old ones. Can you explain it a bit better for someone who doesn't know what a vacuum modulator is? What does it do?

Anyway, I really want to dig into this car but the stupid holiday and all that stuff is getting in the way. I won't be able to put a good weekend into it until New Years.

Darn family! Luckily my wife and daughter both approve of the new garage addition.

Offy intake
Holley 390 CFM carb

No, unfortunately I have a standard interior. I really like deluxe interior. Wish I had a deluxe interior. I had a 68 six banger as well for 25 plus years. Was a daily driver the entire time. It took 20 years or so, but I finally did a V8 swap, went from a 2 speed to a turbo 350 with a 342 rear end. It was a huge upgrade when I did. It was done in a weekend.

Re: New-to-me 1968 base camaro 250 with 20k original miles

Here's a picture of the v/mod and its hard line for a L6/PG from the AIM (Assembly Instruction Manual) - a good Christmas gift/hint, along with a service manual.

The v/mod controls the upshift mph dependent upon throttle positon, a load sensor so to speak. More throttle, higher upshift point.

You will see a short section of hose over the connection of hard line to adapter on the manifold, topside, and to the vac mod on the trans, View B.
Pretty easy to replace, if needed. remove clamp bolt and clamp, disconnect hose, pull out v/mod, replace with new and reassemble.

Welcome to TC,
I've been looking around a bit on Craigslist for prices on transmissions: is there anything I should know about year-wise on a 700r4? I see a lot of them in the $250-$350 range locally. Most look like they're coming off trucks from the 1990's.

THM200-4R would be an easier swap, '84-'88 Monte Carlo SS or '84-'87 Buick Grand National, or simular.
