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.

Since I was pretty much useless for anything else I spent the day taking pictures and actually recorded every round. Too much video to upload in it's entirety, but I will put up part of a round and the final.

Due to my no-show for the first round Brian Rogers got a bye with his bad to the bone D/S 302 '69 Camaro...

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.

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...

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

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.

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.
