Yes, it will. Obviously there will be differences in terms of fueling and electronics, but the 4.3 block will physically fit in place of any G-body motor, v6 or v8 (with the exception of the 3.8 Buicks). The 4.3 is essentially a small-block 350 ci motor with the front 2 cylinders cut off. If the Monte in question currently has a 4.3 as well, it will be a direct swap, you will just need to use the engine mounts off the Monte, and not the donor S-10.
