1988 Chevrolet Astro Van mileage: 247,000. It's time to replace the engine in my 1988 Astro. I bought a 4.3 V6 that has come out of a 1991 S-10. When I dismantled it to get it ready to be rebuilt, I found it has a balance shaft in it. Is it true this motor cannot be used? I've been told that the computer will read the engine wrong or something to that effect? Please tell me if this is true or what will have to be done to make it accept the change.
