Motor and Trans mounts

[Steve K]

Slowly working on getting a rebuild 383 put into my 73 Charger. We are expecting to have about 530 HP out of the build. I was going to get new mounts, and am wondering if I should get poly mounts or if rubber mounts will be sufficient. I can only find inserts for the poly units but complete mounts with the rubber inserts.
Thoughts?

rubber with limiter straps are fine even with a 4 speed

Poly mounts are stronger. But, You will get vibration transfer in to the car. That is unpleasant for anything but a race car. The 73 uses spool type mounts, engine and trans. Not the flat ones on the engine that pull apart like on previous years.

I used poly for everything except the engine and trans on my 73. Stayed with rubber for those.
