I'm trying to use the calculator on another website that is often recommended and the problem I have is where you plug in your valve timing degrees ABDC. My comp. cams timing card has all this info at .006 and the calculator on the other website asks for it at .050. Is there some conversion I need? The intake closing is not the same at .006 as .050, is it? I wouldn't think so. I called Comp. Cams cam help number and they couldn't help. The cam in question is the XE 262H for the small block chev.
