4.6 L 3V Compression Ratio
I'm installing upgraded cylinder heads and a new .030 overbore stroker rotating assembly in my 4.6 L 3V. I'm trying to figure out what compression ratio to shoot for with the new pistons. I'm building my engine N/A, so I want as high a compression as possible that will comfortably run 92-93 octane without knock. Does anyone have any past experience with this? I think the stock ratio is 9.8:1 and I was considering going as high as 10.0:1.
