I know that .030 over is a 306. I used to know the formula for calculating CI's by heart but I have forgot, try and google it.

RE: size of bored 302
dont go more than .030 on the 302. if you need more cubes you can stroke it to a 331 or a 347.

Generally, ona stock 5.0 block, you don't go more than .030 over or you increase the chances of overheating and other issues.
