273 to 340 swap

sounds like they put the motor mounts on the wrong side of the ears. that would give you a rough three quarters of an inch misalignment. keep us posted good luck with the swap

Make sure that the motor mounts are on the BACK side of the engine block "ears".

If you have the proper left side motor mount, it should line up with all mounts properly. Only the drivers side (left) mount is different.
