Engine Swap from 3rd gen to 4th

Does anyone know if a 1990 firebird V6 motor will fit in a 1995 firebird that has a v6 in it.

The one in the 95 is blown and i have a good one from a 90 firebird Thanks

Sure it will fit physically, BUT the wireing harness and ECM can't be used with it.

If its a 3.4L in the 95 then it should be possible. Ask the guys in the V6 forum on this site. You may have to swap the intake manifolds and maybe a couple other things but nothing major.
