W2zero- Nice ride, gotta love those fairlanes!

Thanks all for the comments. Now for the dumb newbie question. Standard bore on a 289 is 4" ? correct? I am ready to send the block to the machine shop, but need to have the new pistons in hand so it is an exact bore (going 30 over) and not a rough bore. Want to make sure this motor has never been rebuilt or machined before. so I measured the cylinder and came out with 4 inches. But using a small ruler, really do not have a micrometer, and ofcourse harbour freight was closed here yesterday, and advacned and discount autoparts did not have one. Want to order the parts, but do not want to order the wrong thing. Again, an ingnorant question, but bare with me I am learning one step at a time. Thank you
