Motor Mounts

I've got a '69 Dart bracket car with a 340 stroked to 431ci,solid roller,ported Eddy heads,12.2 compression,4.30 dana w/spool,Turbo Action trans w/brake,8" converter,ladder bar,coil overs,slicks.
I'm running a solid Moroso mount welded to the stock bracket on the driver's side,made my own torque strap type mount for driver's side as well. Running a stock rubber mount on the passenger's side.
I wanted to run a motor plate,but don't have the room to add one with my water pump setup on the car,plan to add one when I can change that.
Do you guy's think this will be strong enough?
