318 with 360 heads

With what slug, overbore, gasket and head cc?
Just enquiring

Right?
I love how people just throw it out there with nothing to figure it by.

Open chamber 318 heads like the 675's have about 68cc chamber.
360 head range from 70-72 cc's with small valves.

Mill .015-.020 and the compression stays the same.

Btw the j heads chamber hangs into the 360/340 bore enough to actually end up about matched to a 318 bore size too.

Flow is power.
Flow increase will also increase the dynamic compression because you are filling the cylinder more.

People just stop thinking at a certain point and I dont know why... Sigh....
