smileys/smiley19.gifHi.I have a 1989 century custum with a 3.3 L. engine and i want to put a 1991 3.3 engine in the 1989. What do i have to change to make itwork,as most everything is the same. Any help would be greatly appreciated.

I can't tell you what all you would need to do to do this swap, but i can tell you a friend of mine replaced the engine in his 86 park ave. it took him 3 days just to get the old one out, then after having figured it all out to get it out, it still took him 2 days to get the new one in!


make sure you have some patience. and label every last wire and hose you disconnect, so you know exactly where they go, without a doubt.
