Compression Ratio

Yeah, i had to think back many years. Same intake and carburetor as the 360, stock compression ratio 318 bottom end, mildly ported 360 heads, 273 adjustable rocker arms and a Comp Cams 270S solid flat tappet camshaft. Sounded like a big block when we opened the headers.
Thanks, I'm going to write this down so I don't forget.
