The motor mount is a tubular crossmember that lays
across the frame rails. After the engine is installed, two 3/8" holes
are drilled through the crossmember and frame rails, and 3/8" bolts are
installed to secure the crossmember to the frame rails. This mount is used with
the stock Chevrolet V-8 mounts (isolators) and the height of the engine can be
adjusted by installing shims or washers between the motor mount and the frame
If you want to make your own motor mount, the dimensions are shown in the Volvo
200 Series V-8 Conversion Manual.
4-cylinder swaybar interferes with the V-8 motor mount, and must be replaced with
the swaybar from a diesel or V-6 model. An IPD swaybar for the V-6 or diesel model offers plenty of clearance from the motor
mount, and is highly recommended with the V-8 swap.
