Not particularly impressive. You can make an engine significantly lighter by changing the short block from cast iron to aluminum. The only problem is long term reliability (if an aluminum block ever overheats, it is significantly more likely to destroy itself than cast iron).
- jabl 9y agoMy car as a cast iron engine block; alas, it doesn't have replaceable cylinder liners nor are bigger piston rings manufactured, so when the workshop managed to crack a piston they ended up having to change the entire engine. Yet another example of the throwaway society, eh... :(
