Motor Plate or Motor Mounts or Both?

[strongman45]

I have a roadrunner, 440 6bbl set up for drag. Car has not been front or back halved but it does have a motor plate. I am planning on a detune and conversion back to something I can drive on the street.

Motor is currently mounted using a motor plate. Should I change to mounts for street-ability and some short highway driving (100 miles max)? What about motor mount/motor plate combo? Just leave it?

A motor plate mounts directly to the subframe and is rigid. I don't see how you would even use factory mounts at the same time. Motor plates are usually used on things like boats or dedicated racecars where comfort and street ability are not even considerations. No flex = rough ride, vibration fatigue of welds any parts that are trying to move/flex. Plenty of "race cars" using motor mounts. Just extreme duty or with torque limiting devices.

If you have a good motor plate, I see no reason to switch back to motor mounts. Using both motor plate and motor mounts makes no sense.

The plate is solid, I just don't want it to be a dedicated race car anymore. I'd like to cruise too, maintaining a little driveability and comfort.

On my street cars. I drill through my mounts and bolt them together with flat head cap screws. Still have some resistance for vibration but solid when under torque from the engine when accelerating. For my street/strip car I have a front plate and mid plate. I made it larger so that I can mount everything on the front plate. Everything comes out with the engine. Nothing mounted on firewall or inner fenders.

I've used solid, homemade mounts for years. Awhile ago, switched to new chinesium mounts. Bad move. After radiator impaled, switched to schumacher mounts. Will re-install my original solid mounts as soon as I get un-lazy.

I don't see how a motor plate effects drivability or comfort. It just won't look "stock". But my bet is that there are many other things that don't look "stock". Enjoy the ride.

I tried going for the stock look. Well, sort of.... Motor plates don't effect comfort or drivability. I street drive mine.
