Author Topic:   motor mounts
posted March 13, 2003 05:10 AM
I'm in the process of building my first race car. It's a late 70's camero with a 350 and a saginaw 3 speed.
I will be running solid motor mounts on the motor. Does this mean I need to run a solid motor mount on the tranny? What do most of you guys run?
Thanks for any help.

I would NOT (run solid mount on the tranny that is). I'm on a 4 car team and we all have basically the same configuration:
solid motor mounts;
motor plates between the motor and tranny;
plate bolted to the frame;
rear tranny mount with rubber bushings between the tranny and the mount.

You have to allow for some flex and/or twisting. As much as we try to minimize it, the frame still flexes/twists. If the motor and tranny are mounted solid to the frame, something's got to give. And you can be assured, it's going to be your tranny housing.

Good luck and take care

we have always gone by the rule that is one is solid the other needs to be rubber we tried solid and solid but noticed back when we ran stock bell housings it would either crack them or break the ears off the tranny

I agree,with racer 17j, If one is solid the other needs to be rubber,to allow for flex.
