compression height
I don't need the ratio, i need the compression height, the pin height, the distance from the crown of he piston to the wristpin. I'm looking for a set of flattops for my 300 and i think i've found a set, but i need to know the pin height to be sure they'll work. It's for a carbed '85 if it makes any difference.

It's 1.78 give or take a few thousandths. It's the same as a 390, as is the pin diameter. There are probably a dozen pistons for the 300 listed on the KB/Silvolite website, one of which is very close to being a flat top. I have a 300 from a 73 F-100 at my parents house that had flat tops in it from the factory. It might have dishes, but if it does they are very small, maybe 8-10 cc vs. 40 cc for the late model stuff.

That's what i was looking to do, either use an old set of 300 rods or rebuh a newer set to accept the .912 pin. Unless i'm looking in the wrong place it's cheaper to buy the 351 pistons and rebush the rods than it is to buy a set of "performance" 300 pistons.
