Any benefit or drawbacks to solid motor and tranny mounts?

Default mounts

I had to use them, I installed the stock mounts with my 385 and the first time I barley touch the gas broke the mounts and punched a small hole in the heater box (thats torque!). Tends to be a bit more vibration with the solid mounts....you can try to cut down on this by using urethane mounts.

One benefit of the solid mounts is that it stiffens the front frame of the car; keeping it from flexing as much.

don't use solid mounts on the engine and trans, leave the trans a normal one, otherwise you may crack the tranny case.

I am running a poly one the driver side and rubber on the passenger side, the eng barely moves when you get on it but does not vibrate at idle with a slightly lobey cam since the rubber side absorb the vibration

I agree. I resisted solid mounts because of the vibration at idle but I also wanted to stiffen the front frame up especially around the steering box so I went solid. I honestly don't notice a vibration and wished I had gone the solid route years ago.
Like Twin Turbo said don't go solid on the tranny mount. I left mine poly.
