Thread: Piston clearance??

Tweet

Sorry Pat, I didn't realize I posted those crazy #'s....it's a 400. I went back and edited my post and fixed that. I understand that it's not a good idea to finish a block without the pistons, but the point is that this block wouldn't clean up any less than 4.165, and even then it still had faint signs of wear at the very bottom of two cylinders. I couldn't have went any less. I just took a gamble on this one cleaning up without having to take it to .060 over. I took it the bare minimum to clean it up and then ordered the piston after it cleaned up at 4.165. I should have measured the pistons when I got them to make sure they would work but I didn't so now I have to come up with a fix. Should I run them with the .004 clearance I have or try to find different pistons? It just seems to me that the keith black pistons I have are too small. If they require .002 clearance and they measure 4.161 then the block would need to be fiished at 4.163........that's not .040 over LOL.
