273 to 340 swap

My car is a 68 4 door 270 originally a 273 V8. I'm having a shop change out the motor to a 1969 340. They got 340 motor mounts, when they put it in the motor was cocked about an inch forward on the drivers side. They then used the 273 mounts but had to use spacers on the drivers side. Now the engine sits forward about an inch so the transmission mount doesn't line up. Should this motor fit properly in a 4 door with no mods to either the engine or transmission mounts? Are there aftermarket mounts for a direct bolt in?
