The general consensus of 350SLC (euro) vs 380SL (U.S) seems to be pretty is would be pretty much comparable but, gives a slight nod on the power side to the 350SLC (euro) model.
I find it strange that as much as I have searched through different message boards and such, I've yet to come across discussions centered around increasing engine displacement or, specific recomendations for increasing the combustion chamber in the heads, porting and, things of that nature.
What does anyone know...
