Hi,
I need to find an approximate compression ratio for my 401 Nailhead. Its bored 60 over, so I can calculate the increase in swept volume making the cylinder volume 15.4609 cubic inches.
If I knew the volume of the cylinder head combustion chamber and the thickness of a standard gasket I could approximate a compression ratio.
Can anyone tell me what the combustion chamber volume is on a 401 Nailhead?
Many thanks
Gus
