Asked in Chevy Monte Carlo
Can you swap a s10 engine into an 85 Monte Carlo?

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.
