Rebuilt Engine Trouble

[BULLITT65]

Good point on the drive shaft. I was thinking more about the excessive noise he referred to. But I agree start with the simple stuff like compression check, and easy items and go from there.
Being on site is totally different than trying to diagnose from someones description online. If he starts narrowing it down, he will figure it out.

Checked compression and did leak down test on all cylinders. All checked out ok.
Went to get new plugs from NAPA and low and behold they went to give me different spark plugs.
Said the NKG 8177 plugs I had (and bought at NAPA I might add) were not correct for the 350 Camaro in 1967.
So they gave me Autolite N85 plugs.
I installed them and will try to set up and fire tomorrow morning.
I do not think that incorrect plugs can cause a woggle/shake like this? But thoughts out there?
I have checked firing order over and over.
What I am worried about is mayby not having set the balancer correctly at TDC when I assembled?
Or I did something else wrong on assembly to have timing off really bad?
Appreciate all of your thoughts even though it is far from all of you.

Thanks

[BULLITT65]

Glad the compression is good.
I am not sure you could have installed the (stock) balancer incorrectly unless you put it on backwards. There is a slot in the crank for the key, and the balancer has 1 has one slot as a key provision.
Spark plugs- I could see if they sold you to cold of a plug, and they fouled out that would cause a misfire shaking type response.
If your spark plug gap is not correct, and not all the plugs are firing correctly, that could also cause the issue.

So what did the end of plugs look like that you just removed? Black, white,  brown? 

[Axlman]

Plugs were very black and carboned up with some white burn on the ends.
Will try to set up the distributor and timing and fire tonight.

[BULLITT65]

Well perhaps they were to cold of plugs and fouled out right away. Good luck tonight, hopefully you will be in the clear.

Axlman,
 AC plugs have always performed better than any other brand in my chevrolets. Our local NAPAs in this area no longer stock AC parts but can order them, they will sell you what they have in stock if you let them. Is the camshaft degreeded properly ( the two timing chain gear dimples should be together).
     Good luck,

For what is worth.

I had lots of troubles when I left out that thin sheet metal heat passage tin gasket out (lack of installation) under the q-jet carb, 8$ part cause fouling and rough running if it moved at all.

You checked and the bolts for the engine mounts are installed, right?

And bolts are in the transmission mount and crossmember, right?

Remember it is doing it at idle, and unless you are doing a hole shot and putting a lot of torque on the drive train those mounts are not going to play a factor yet.

Always good to re-check those after putting a motor/trans back  in though.

[bcmiller]

Don't be so sure on that.

[BULLITT65]

Well I have driven cars with broken motor mounts and the only time they became a factor was when I would do a brake stand. Every so often the motor would torque over and the throttle would stick for a second or 2, but At idle or cruising down the road I never had any loud noises like the OP has mentioned.
I mistakenly mentioned the drive shaft being out of balance, but again just sitting at idle, it would be a non-factor.

So yes, you can re-check the mounts, but if it is sitting still and having issues I think it to be less likely...

[janobyte]

Still need addressed the increased fuel consumption. 7 tanks, what distance traveled?

Any un-burnt fuel finding it's way in the exhaust or puddles in the carb ?


Compression good-ignition: firing order/timing/quality of spark-carb: gasket leaks/adjustments/internals

Plug readings indicate engine running rich, all cylinders. Color of exhaust gasses ? Black smoke under initial load? (taking off/accelerating)

Oil contaminated with gasoline?

Same experience as Bullitt concerning engine mounts (more so my beaters when I was a teen  )

Come on guys.   Remember, check the things that are easy and don't involve any cost first.  Doing this will take a few minutes and if things are OK, then move on.  Process of elimination.

I actually think there is more than one issue, but without seeing this "wobble" in a video or in person, it will be hard to diagnose.
