I am sure it will work, With a bit of fab work, Is youre
1989 S-10 Blazer with a 4.3 fuel injected?, How about the 85 monte carlo, Motor fuel injected or carbed?. Well you could use the block from the monte carlo, swap over the intake off youre Blazer, Then u wont have to swap over the wiring harnesses, I would just make sure get things are complete from the monte carlo motor so then u dont have to go to the wreckers to grab parts.

GoodLuck.

Thanks for the reply. Im gonna try to do this swap with my brother. Im thinking I should keep the intake, fuel injection, wire harness, and oil pan from the Blazer and everything else should be fine. What about the motor mounts?
