- Neil -- I think you're on to something there. Adding silicon to aluminum alloys reduces their temperature coefficient of expansion (CTE). Raw aluminum is about 13 millionths of an inch per inch per d

- Benn - Just guessing here-- Heat the block and/or cool the pistons during assembly. If the block cooling passageways were completely sealed without the head being installed or if it's an Offy type in

- Sounds good on paper but I think asking an assembly robot of suitable envelope size to hold closer than .005 is a bit much. Build something like that into a 200-250 degree oven and try to control te

- I have been struggling with this one ever since it was posted a week ago. Kind of sounds like something a journalism major would naively accept without looking into it further. If you use a coefficie

- It's a lot easier to work with liquid nitrogen to cool parts than it is to heat other parts in an oven. Regards, Neil Tucson, AZ --Original Message-- From: land-speed-bounces+neil=dbelltech.com@auto

- Sure, liquid nitrogen is the favored industrial material. I kind of figured it might produce too much vapor and make it hard to see the parts during assembly. Also there might be some worry about th
