1982 380SL / 1991 420SE / 1978 VW Westfalia Camper Bus.
I just bought a 72 running 350SL with a broken head bolt so it smokes like a locomotive. I found a donor car, a 74 450SLC with a running engine of a 120K miles. I had the 450 motor out and found some differences in the intake manifold due to the smog pump set up and few other things. The main concern I have is the engine oil cooler that is on the 72 350SL that is not on the 74 450SL. Can the swap be done? What else will I expect to change out. I don't want to start pulling out the smoking but running 350SL if the swap is not possible. Please help.
