Universal engine motor mounts are perfect for engine conversions and can be swapped side-to-side to move the engine position 1-3/4" forward or backward from center.

These are for classic Chevy small block and big block engines with a 3 bolt mounting pattern. Includes block mounting hardware. Sold as a set.
