Today, dollar for dollar, is the 318 faster than the 340 ???

Yeah kind of like tearing a engine down and then physically measuring the crank just to see if it even needs ground or if a simple polishing with emery cloth will work. Or looking and measuring a cylinder bore to see if it actually needs bored or if a simple honing will keep it within specs. Ect... physically measuring whether parts are within spec or not. Instead of throwing money at it

No sense measuring anything if you are just going to run it. When the main bearing clearance is .0022 plus a couple of tenths minus zero and you have a journal with .0003 taper it’s already out of spec. I won’t run that. If you measure the bores and it has .0010 taper it will take another thou and a half to get it straight so that means the bore will be too big for the pistons. You can measure all you want but if you are using the FSM tolerances they are so sloppy it’s not worth measuring. Maybe you should go hang out with some real engine builders and see what they do. Unless you don’t want to learn little buddy.
