Default Leakdown Numbers Needed
What should I expect to see for a % on an FE is good condition, and at what % should I get the hoist ready?

The engine in question is a 390, unsure of the internal specifics as far as ring type, end gap, etc. Heads are Edelbrock with less than 5,000 miles. No loss through carb or exhaust - it went past rings.

I ran the test, but the numnbers are at home - just need to know how to interpret the data so I do not make a costly mistake.


Thanks guys,

Jeff
