I was told that the long block from a 1976 300d could be assembled with the rest of a 300cd engine and there would be no "issues". At the very least I am seeing that the oil pressure hose will need an extension (the oil filter is under the fuel pump in the 76 300d).
However, I am also noticing that the injectors and fuel pumps for the 2 vehicles are different...
Does anybody know what issues I might encounter if I tried this 300d block with the 300cd valve head?
Is this a terrible idea?
