Pressed Vs. Bushed Conrod's

Dumb question, what's the difference between the two and why might one be better than the other?

Costs more money to bush the rods with bronze bushings for floating pins. If it's a race motor that will be torn down periodically, floating pins are easier to disassemble. If it's a street motor that will only come apart when it's worn out, pressed pins will work fine and are cheaper.

Couple of different ways to keep the pin from rubbing the cylinder wall with floating pins. You can use a lock on each end of the pin that fits into a groove that's machined into piston, or you can use a teflon button that fits into the end of the pin on each side and then the soft button rubs on the cylinder wall instead of the hard pin. Some guys worry about the locks failing, so prefer the buttons.
Here's an example of what the buttons look like....

How long can the teflon buttons be expected to last?

Teflon buttons usually last at least the life of the assembly. I know a couple of truck pull/mud guys that re-use them several times..
