I recently scored a ‘68 318 for my ‘69 Dart. I’ve heard lots of good things about the earlier 318 blocks being beefier and the ‘68 318 having 9.2-1 compression ect ect. Anything special about the crank or rods? I also noticed it has open chamber heads, so if i put my closer chamber 302 heads on what kind of compression might I be looking at there? Blocks getting torn down and rebuilt, but i’d just like to know what to expect to find. Thanks all!
