The clutch fork in my 67 camaro hits the body everytime I use it. It will hit the body before my clutch hits the floor. Is it adjusted wrong? It's a muncie 4 spd, and I'm using a Lakewood Scattershield. I'm using the stock clutch linkage. I could use any advice on what might cause this and how I might be able to fix it. Any help would be much appreciated. Max.

I would bet you have the wrong throwout bearing installed. Did you change from a diaphragm style clutch to a three finger style? The diaphram style clutch uses a short throwout bearing that is about 1 1/2" long. The three finger style uses a throwout bearing that is about an inch longer. If you use one that is too short the linkage will hit the firewall before the clutch is fully disengaged.

You mentioned the linkage linkage, and I don't want to assume anything but are you using a Lakewood fork? If so it will hit the floorpan. Ditch it for a GM fork.

I really don't want to have to pull my transmission another time but I guess that's where my problem is. Thanks.

You could also have the wrong fork. 10.4" is #3892632, 11" #14066235.

These part numbers may have been superseded.

hey Maxwell. Ive run into the same situation with my 67 camaro. I had to replace the throwout bearing in mine and also the clutch fork. The forks were slightly different as I have a saginaw currently in it with a 10.4 clutch i would guess. The fork I had had more bend for clearance and when I installed the new one I was banging it on the floorpan underneith. I had to do a little floorpan bending at least temporarly.

I have a question for you guys here too that relates to this...!!

As my car was a 6 banger previously. and the previos owner droped in a 350. The bellhousing is very tight against the firewall. so tight infact i cant remove the upper drivers side bolt on the housing. the motor will have to be pulled out if I want to change my fork again. could he possibly used the wrong motor mounts hat wuld have loceated it closer to the wall.?

Maxwell ill keep you informed if i figgure my end out. Im picking up a Munci tomarrow and will have to deal with that problem again.

67 and 68 used a tall frame mount and short motor mount.
In 69, GM came out with an improved interlocking motor mount that was thicker, so they shortened the frame mounts.
This setup was used beginning with the high perf engines only in 69, and the standard engines used the old non interlocking mount and taller frame mount.

You may have a 69 type thick mount on your car, which would raise the engine up.
There are now short interlocking mounts avalable for the early type engines.

I have my engine out and looked at the parts in question. The frame mounts and the motor mounts seem to be correct for a 67 350.

I checked my clutch disc and its 11 inches in diameter. Is this not stock for a 67? I compared my clutch fork to one shown in the Year One catalog and it appears to be a GM fork for 67-72 Camaros. Did 67-72 camaros come with 11 inch clutches? I guess I answered my own question thanks to William. I should be using part #14066235.
