Guys, as some of u already know, i have a w126 500sel 1984 euro spec with the CSI old one ie not the ke sys. now i am considering swapping in a 560 full head.
how possible will that be, i am looking for a simple job with minimal mods? i dont even want to cgange to the newer csi sys.
your thoughts are highly appreciated. Will it give me more top end? cause this 500 is good low down but seems like strangled above 5000 rpms.
