Re: Break In Period

Since sleeve-valve engines are extremely tolerance-specific engines I would imagine that this was done so the engine could be properly broken in. Too much heat and too little clearance and I would imagine that it would seize the sleeves and break the cranks.

I've always wondered how well these engines would do if one was made out of completely modern materials with modern methods. Ceramic sleeves and high nickel cylinders come to mind here. Personally, I'd like to have one of the Knight V8 engines to play with, but those seem to be more rare than Packard V8 manual trans setups!
