I have a 97 blazer with a blown motor I have a motor out of an 89 s-10 truck just wonderin if I can just stick the motor out of the 89 in the 97 or will I have to change the throttle body, intake, and or heads? this is just one I am trying to flip so the cheaper and easier i can do this the better. Thanks for any help.

 

Very different engines. You are going to have a much easier and cheaper swap if you get a 96+ motor.

 

I already have the other engine in my garage and have had for a year now
