Not so fast. If the old engine was a slant 6, you will need to change the k-member. Depending on the year of the 340, you may need to get the correct flywheel or torque converter because some of these were externally balance. Early 340's were a forge crank and the later ones were a cast crank.Easy pull old motor out put 340 in!!!!!
