In Reply to: Why Alusil? Why not steel liner? M60 posted by D L on October 25, 2000 at 00:50:28:

The Alusil has always been used in the V12 engine. I don't know why they had two alternative methods but I'll bet $$$ has something to do with it. I think the infamous Chevy Vega used a high-silicon alloy with the aluminum etched away in the bores, mated with iron-plated pistons.
Both wet and dry steel liners are not with their problems (sealing and/or heat transfer) and expense but have been used for decades. The all-alloy block is a logical evolution. The Jag/Lincoln LS engines have aluminum bores as does your Briggs + Stratton lawnmower engine.
