Hi guys.
love reading your advice and posts.
just recently bought a 1986 420 SEL at an auction.
me need an engine. or alot of work according to the mechanic.
he thinks cheaper to get engine.

i saw a few on ebay for cheap...but kinda far away.
i was wondering if i can put a 560 SEL engine in me baby?
will the computer work?
there is a 560 for sale here in l.a.

any wisdom here would be greatly appreciated!

Thanks
