Title: Head Markings Question
Post by: Kazoo on March 22, 2014, 18:28:53

I Noticed that the markings on the cylinder head (large and cast in on the drivers side rear side of the head)

It says 280 SE/A

Can anyone tell me about this, does this imply that the head on my car is not original and came from a 280SE sedan...

My car is a 1971 280SL

THANKS

Wayne

I just walked out to the garage where my engine is sitting on a stand to confirm that my original 1970 280SL has the same markings as yours.  To the best of my knowledge the SE/a denotes a fuel injection head and the same head was used on both the SE and the SL.

I recalled reading this in the Tech Manual ... 

And here is what Benz Dr. has said ...


"Dan Caron says: the 280 SE/A is correct for the 1970 and 1971 280 SL cars. The SL engine and SE engines are virtualy the same anyway. Small differences in the plumbing and manifolds but nothing all that much. Now the 280 SL euro engine from '68 to '69 is a different thing. Higher lift cam and longer duration. About 10 more HP. So your car can have a 280 SE/A engine and be 100% correct."
