i believe its something like i asked you about... as long as its not a paper element, i'd think it be ok...but lower the micron count, the better(less restrictive), right?

Re: '67 Camaro E/SA redo
 

Beech Bend 4-12-2014 TNT session. Went today to test some carbs and misfortune continues to plague me. First pass the car barely lifts the wheels with a 1.52 60' and runs a 11.47et...it was all downhill from there.

Finally realized the convertor had given up...tightened up so much the last pass it literally drove of the line for 30' before it took off. Can barely keep the motor running in gear. I'll pull it out in the morning and see what I can find lying around the shop for a temporary replacement. :mad:

Re: '67 Camaro E/SA redo
 

Sorry to hear that, Rich.....I'm sure ATI will take care of you. On the bright side, even with broken pieces you were still .23 under. :) -Al

Re: '67 Camaro E/SA redo
 

Yeah, I'm going to send it off for repair and keep it as a spare. I will order a new one Monday...may have something in the shop to stick in there for the upcoming Combo race this Saturday.

Re: '67 Camaro E/SA redo
 

Looks like my initial diagnosis was not complete. When I pulled the convertor out I found this...stator support shaft the correct terminology???

http://i434.photobucket.com/albums/q...ps518c2658.jpg

By the appearance of the shear site it looks to have already been broken...there are three shiney spots which is probably all that was holding it together. I'll attribute this back to the prior driveshaft/housing perch failure fiasco. I told you it was rather violent lol!

Anyway, with this set-up out of commission for a spell I slipped the PG back in temporarily. I'll try to hook up with Thomas at Bowling Green and pass off the trans and convertor to him for repair. Convertor status is unknown and I think it would be prudent to let ATI cut it open for a look-see.

http://i434.photobucket.com/albums/q...psfe1c5f3d.jpg

On a positive note the added fuel gauges showed me that the fuel system is working well...was still showing 6-1/2psi thru the lights.

While the car may not be as peppy with the PG, I'll still be at the Beech Bend Combo race this Saturday...what else could go wrong? :p

Re: '67 Camaro E/SA redo
 

Dang man! You are hard on stuff! hehe... atleast you found the problem...

Gimme some info on the guage line and guage that you installed... i need to do that as well...

Re: '67 Camaro E/SA redo
 

Beech Bend Combo bound in the morning. This will be my first race with this car and the first S/SS race I have ever entered. I'm sure it will be a learning experience. I'll try to get some pictures to post up after the race.

Re: '67 Camaro E/SA redo
 

Please be safe and may God Bless you!

Re: '67 Camaro E/SA redo
 

I seem to be in a perpetual snake bite loop with this car. One qualifying pass this morning and I was rewarded with a cracked transmission case. There has to be some misalignment or binding somewhere. Body bushings look tight and fine...going to investigate the motor mounts before another transmission goes back in. I marked the crack in the case so it would show better in the photo's.

Re: '67 Camaro E/SA redo
 

Dang,, Rich I'm sorry to hear that this car is putting you through the ringer so much. You know eventually it will get down the track, but I know (heck, we all know) that its very frustrating at times. I just got done with a trans R&R 2 weeks ago and hated cutting my new ATI converter open to clean it all out. Hang in there, we're pulling for you.

Re: '67 Camaro E/SA redo
 

I'm on a mission now...I will figure this one out. Some video's coming shortly. :)

Love this car...

Re: '67 Camaro E/SA redo
 

Rich, that's a darn shame. I was anticipating looking here this morning and seeing some positive results. No need to bore you with all the stuff to check....there was a good thread here recently on this same subject: http://classracer.com/classforum/showthread.php?t=52403

On the subject of motor mounts, I've got a set of Energy Suspension units to replace the solid mounts on my Nova before I take it out.

Have a good Easter and keep us posted, okay? -Al

Re: '67 Camaro E/SA redo
 

Yeah Alan...there is an odd match of motor mounts which bugs me a little, but I'm unsure if they have any role in the current problem. The trans mount is urethane.

Driver's side...

http://i434.photobucket.com/albums/q...psafd6fdbe.jpg

Passenger side...

http://i434.photobucket.com/albums/q...ps15bba38c.jpg

This car was as smooth as silk before the rear housing perch failure...ever since that time there seems to be an odd vibration at different points on the track. I wondered if it was just my imagination, but the car just doesnt feel the same since.

I did replace the u-joints...how does one check the straightness of a driveshaft?

Re: '67 Camaro E/SA redo
 

Rich, I would defintely get the driveshaft to a shop and have it checked for straightness & balance. It's hard to tell from the pics, but check the motor mounts and make sure there's not a mismatch of heights....there is a 'tall' and a 'short' motor mount. -Al

http://www.jegs.com/i/Energy+Suspens...1114G/10002/-1

Re: '67 Camaro E/SA redo
 

I'll have to do some measuring today, but I think you are right about the difference in mount height just eyeballing it. I don't understand why someone would do that. I'll have to do some research for a local shop that can check out this drive shaft. Think those poly mounts would hold up?

After giving it some thought I believe I'm going to just go ahead and have a new drive shaft built and change over to 1350 yokes...no sense to keep pounding on this stock 45 year old shaft and 1310 u-joints. My only other decision then will be using poly or steel motor mounts.

Re: '67 Camaro E/SA redo
 

Another thought from looking at the pictures. What kind of tranny mount are you using. Solid or rubber? You have a problem that can get maddening real quick.

Sorry, hadn't read all the thread, see you have urethane mount for the trans.

Re: '67 Camaro E/SA redo
 

Urethane -

Re: '67 Camaro E/SA redo
 

Broke a turbo 350 case in my Chevelle a couple years ago. I have steel mounts on engine and rubber on trans. My trans guy told me to make some spacer bushings at trans mount to leave a small amount of play in the mount -about a 1/16th. Had to open up slots in crossmember to fit. Trans guy does a lot of trans and anybody that has broken a case he has them do this with great results.

Re: '67 Camaro E/SA redo
 

Rich, the frame mounts are also different between small blocks and big blocks. It's easy to end up with a mismatch of motor mounts and frame mounts. And from side to side as things have been swapped around over the years. Generally, the dead give away is if theres a 1/4" spacer or stack of washers between the engine mount and the frame mount to compensate for the motor mount width...but not always. I've seen aftermarket solid mounts that are combinations of both dimensions. Here's some dimensions to help identify what frame mounts you have:

Small block:
Driver's side: 2- 9/16" tall
Pass side is 2- 3/4" tall.

Big block:
Drivers side: 2- 7/8" tall
Pass Side: 2- 1/2" tall

Basically, small blocks use the 'short/wide' setup and big blocks use the 'tall/narrow' setup. The '67-'69 Z-28's supposedly use the big block style (tall/narrow) setup....whew. :(

Just my understanding of it...... -Al

Re: '67 Camaro E/SA redo
 

I'd say it has to do with the rear end fiasco, when it wrapped up...i could be wrong... Sorry you having so many issues... I havent even gotten my heads off yet...maybe tomorrow eve...

Re: '67 Camaro E/SA redo
 

This was the qualifying pass which broke the case. Pardon the length...I'm just not into video editing today. :p

http://youtu.be/lqdysYDdDKs

I'm going to install a torque link no matter what motor mount I decide to go with.

Re: '67 Camaro E/SA redo
 

sorry about the bad luck you are having.
I use urethane mounts on engine and transmission.
Energy suspendion mounts have a posi lock set up built in so they don't split apart.
I've bent solid mounts on engine 2x. I threw them in garbage.
I've used stock rubber engine mounts with a engine torque limiter on drivers side also.
a turnbuckle set up attached to frame on one side, cylinder head on other. works perfect and used by my friend who welded bracket to frame. He runs and builds stockers and index cars.
This is on A Bodies but same rule applies.

Re: '67 Camaro E/SA redo
 

I fought something like this awhile ago, I kept destroying driveshafts and transmission cases.
Long story short the original driveshaft skip roped and one thing went undiagnosed through all repairs.....the transmission crossmember got bent downwards. The third instance we went and measured driveline angles and reset them back into a favorable set of angles. FWIW just my 2 cents

Re: '67 Camaro E/SA redo
 

Rich,
Be sure to check the pinion for run out as well.... I`m betting the Driveshaft is the problem . Good Luck!:)

Re: '67 Camaro E/SA redo
 

New drive shaft being built along with 1350 yokes. :)

Re: '67 Camaro E/SA redo
 

The best money I ever spent..

Re: '67 Camaro E/SA redo
 

I don't know for a fact that there is anything wrong with the drive shaft...sent it to the builder to spin test it as they build the other one. It's about time for an upgrade anyway as there will likely be a hp/tq increase in the near future. I'm just trying to eliminate any weak links where I can...wearisome with all these breakages lately.

New low profile solid mounts ordered along with a tubular transmission crossmember.

Re: '67 Camaro E/SA redo
 

Hp/tq increase?? Are you thinking about one of the 396 combos, Rich?
Danny Durham

Re: '67 Camaro E/SA redo
 

The wheels are turning, hehe. ;)

Re: '67 Camaro E/SA redo
 

I'll bet they are! I don't know how much lighter a '67 is than a '69, but I always liked the 396 '67 Camaros. Good idea finding all your weak links now,,, good luck the rest of the way.
Danny Durham

Re: '67 Camaro E/SA redo
 

Just got confirmation this morning that the 200 case was cracked as well. Even with all the components being replaced on this car I want to get as many eyes on it as I can before it goes back out. The builder of the new drive shaft reports that the old shaft was just slightly out of balance...I'm thinking it had little to do with our problems.

The following parts have been checked and/or will be replaced -

New drive shaft w/1350 yokes

New tubular transmission crossmember (will stick with the poly mount)

New solid motor mounts (both being equal height)

Sub-frame bushings checked for tightness

My best guess is the mis-matched motor mounts were the primary cause of most of the woes we have experienced...have yet to come up with a logical reason for someone doing that. I believe the original slapper bar traction device masked/cushioned the problem. With the introduction of the Caltrac's and the subsequent higher shock loads things began to fail. With everything in it's proper place and working together I predict some low 1.40's in 60' times. Btw, the torque convertor appears to be unscathed.

Re: '67 Camaro E/SA redo
 

do u have the side stiffening bars on your trans case??? FED 387

Re: '67 Camaro E/SA redo
 

Rich, where did you get the tubular trans cross member from? Is it lighter? Or easier to install? Thanks

Re: '67 Camaro E/SA redo
 

Yes FED, but there is only so much they can do with my abuse lol! :o

http://i434.photobucket.com/albums/q...ps595a31ea.jpg

New crossmember from http://srdparts.com/index.php?page=s...emart&Itemid=1
Appears to be a quality piece and it will help with the shift cable routing.

Re: '67 Camaro E/SA redo
 

When you get all of these parts in place with the proper mounts and such ,spend some time measuring up your driveline angles. I suspect you may find that they may not be at ideal angles.
I say this only because of the violence you described with the diff situation, it reminds me of the troubles I had with my car. The root cause of my issues were the engine/trans and diff were doing this ( \-/ ) as an over simplified example. I kept knocking out driveline parts until we corrected that issue.

Nothing more frustrating than chasing a problem that hides in the shadows. good luck with the car

Re: '67 Camaro E/SA redo
 

The angles were perfect until the perch's collapsed...:p

Re: '67 Camaro E/SA redo
 

Thomas Arnett comes thru once again. Drove to KY this morning with a buddy who is building a '68 Camaro E/SA and we picked up two identical fresh metric 200 transmissions. Everything is bolted back in the car with the exception of the drive shaft which should be in hand Monday. See you guys in Bowling Green May 18th. :)

Re: '67 Camaro E/SA redo
 

Anyone here running a similar car to ours? I'm thinking about ordering Landrum mono's and the spring rate I need I'm unsure of. The car only has 1330 pounds on the rear...think the 150 pound springs would be too light?

Update: Took the split-mono's off today and put the original stock mono leaf springs back on the car. It feels much better now...will have to test it to find out if I went the right direction.
