Car takes ALOT to move it...

Could be a few things. Loose torque converter, I have a 10" about 3000rpms stall. If I put it in gear foot off the gas and brakes it wont move till I give it gas. If I stab the gas pedal the converter will flash to 2500 rpms before the car moves.

Are the breaks dragging ? try adjusting them ? Is something rubbing ? check the tires.
How about wheel bearings ? are they in good shape ? are they to tight ?
