83 sedan deville engine swap 4.1 to a 425
My first post. Here goes. I have an 83 sedan deville with a 4.1. Right when I was about to have the 4.1 rebuilt, I found someone local with a great running 425 from a 77 deville that he is parting out. I've been told by more than a few people that spending thousands to rebuild a "crap" engine like a 4.1 is simply a bad idea.
I just want to be sure, the 77 425 will work fine in my 83? Will i need to convert or change any set up in my 83 to make this work, or is it a pretty basic swap? Also, is the 425 a much more reliable engine than the 4.1? Thank you everyone. I'll get more involved and post some pics of my car. I'm originally from Detroit and my father was an assembly man and machine repair man at Cadillac, so this care is in my blood and has been a dream for me. Its really the only vehicle I have a strong affinity for. |
