440 mounted with a motor plate in a 67-69 Dart

motor plates,elephant ears, whatever you want to call them were and are great for the racers...for the extra room, weight savings, and simplicity...hard to beat. But, for a street ride ....it is nice to damper the driveline vibration.

just my opinion, no charge...and , once again, around here...you get what you pay for.

I have seen plates with a flat foot welded on the bottom, so a rubber or urethane isolator could be placed between the plate and the frame. The only vibrations I ever noticed were at dead idle, and anything with a cam is gonna shake the car anyways, regardless of mounts. I try not to idle around too much anyways. Just my opinion.
