273 302 318 340 build

Thanks. Im wondering how you figure static vs dynamic compression ratio? I know static means "theoretical" and dynamic is the "actual" or working compression.
One of these 318 engines will be built whether its for the cuda or the truck.
Thanks again!
FWIW, I ran numbers on the 526's vs 285's with your heads unmilled and a .028" thick head gasket and got 8.9 vs 7.8 Static CR. So the 285's drop over a point in CR..... and Dynamic CR with the 285's will be waaaay down with a 270 cam.
