First a little history. I have a 69 coupe 4 speed with a fresh 455. The car ran great no problems. I just installed a set of headman headers and Pypes cross flow exhaust. To install the headers I had to remove the starter and clutch leakage. I removed the motor mount bolt on the driver side. I jacked the motor by placing a pipe under the block where the starter bolts. When I lower the motor back down the motor must have shifted to the rear. I loosened the trans mounting bolts jack the motor again and lined it back up. The exhaust I welded and installed clamps. Everything looks good except the return spring for the clutch hits the header. The header is also right next to the steering column mounting bracket. This is the bracket that trans reverse rod is connected. Now for the problem.

Everything sounds good when I start the car. When I drive it sounds like the trans gears ar going to fall out. It is bad in 1st real bad in 2nd and 3rd. I did not try 4th. I do not see anything rubbing. Has anyone ever run into this problem any help would be appreciated.

Thanks for the input Banshee. I did check the cover and there is no damage. I also think it would make noise just idling.

Did you remember to bolt your motor mount back down?

did any shims fall out when you removed the starter, is is possible it is sticking a little? I know this is unlikely given the fact you have gotten it into many gears but if the starter is sticking on the flywheel maybe ???

My flywheel was rubbing the inspection plate and making a wierd grinding noise, but only under hard throttle. It took me a while to figure it out. The crank moves radially in the main bearings a certain amount depending on the load.

Did you check if the trans reverse rod hits the header and moves when the engine torques in gear?

Rocky you are correct. The bracket was close to the header. When the motor torqued up it hit the bracket. I removed the trans reverse lockout bracket and all my problems went away.

Thanks everyone for your assistance.
