Can you swap a 4.3L v6 from a 93' Chevy Cheyenne with a stock 5.7L strait over or will you need a new trans or just a bell housing or is it possible?
To be sure call any salvage yard and ask them to check this in their HOLLANDER cross reference. Then you will know for sure. The trans will work fine and bolt up, the harness should also work. You will need to get the v8 motor mounts and the ecm from the v8 otherwise the computer will limit the rpms at about 4800 rpm. The fan shroud must also change to a shorter version, the starter may be different depending on the flywheel.
