Hello Ryan,
I have an big heritage of Mercedes Benz Engines from the 60ties, so I can offer you a lot of different 230SL engines.
Overhauled? Or in working condition? Early versions or late? With stamped numbers or clear?
But each coin has two sides, the bad news is, that I am located in Germany. So we have the ocean between us...
So my advise is, that the best, what you can do is to contact Metric Motors in Ca. I heard here in this forum a lot of warm words about their competence- so please contact them first.
If they can not help you, I think I can do!
Best wishes from Germany!
Sebastian
