I'm near welding in the motor mounts on my 350. My floorboard is against the trans. Bellhousing. It's just touching at the top. Is that a problem? Can't get the front of the engine lower because the balancer is 1/2" from the Power Steering. Running a Fan Clutch and Fan so I wanted to get the engine as far back as possible. (I have 2 degrees neg. on the Balancer so the Differential Pinion can be set at 0 degrees) Will noise transfer into the cab with the floor touching the transmission?
