for 4.165 bore 6"stroke am I wrong in thinking that a 4.160 piston is going to be right on

So

So..... you are buying a piston to fit your bore size? Normally, you buy your piston and hone the cylinder to proper clearance. Or maybe I'm just misunderstanding your question.

lol yea! correction! 4" stroke and 4.160 pistons for a 4.165 bore and yes buying pistons looking for pistons 4 possible block swap.Have a 434 sbc right now with a serious knock havent opened her up yet but I might have found an Iron eagle thats been punched out allready and since the skirts on my Ross pistons are scratched was thinking on a used set of JE's that are in good shape.......mind you this is for a weekend cruise car and I need to use every thing that I can from the 434 right now due to lack of funds,yes i realize that the eagle has a raise cam location... and will need a new cam
again! just dont have the confidence on the oem block anymore

The 4.165 bore block was more than likely bored, then honed to fit a 4.165 piston ... not a 4.160. As far as the cam, you can still use your existing cam (I'm sure it's a small base circle) unless the cam journals aren't standard on the Dart block. Then there is a different pan, shorter pushrods, different timing chain, slip collar distributor & oil pump shaft that will have to be run with the Iron Eagle. And if it is a tall deck, intake spacers and maybe headers!
