Cylinder Leak Down Test

Fellow Motor building fans,
Does anyone have the specifications on Cylinder leak down rates? I am looking for the specification for 100psi in, what should be the out, if all is OK? I was not sure if it was around 10% for a healthy motor? This test is being done on a 429SCJ Wedge if that makes a difference......

Thanks for any input!
L8R,
Brian

Brian, John at Anthem Motors did a leak down test on my 460 when we suspected head gasket problems. Call him. He said mine were within the 10% limit. He gave me the results on each cylinder: low was 10LBLs high was 16 LBLs although I don't know what a LBL is (pound/liter?)

Bob, I must say that you are a welth of information!
I thank you for the information, and what about that race.........
You will need to show me how fast that car really goes!

Keep it above 100!
