Not hung up on anything. I own a 318 Belvedere 2 door 1970 B-Body. No A-body here. The 518 and 8.75" rear in it are already built to handle over 600 hp. Not my first rodeo. I don't see the point to spend a boat load of money making the original 318 stroked. I can leave the 318 the good dependable motor it is and buy the 440 or something like it already built. Everything I have done to my car can be removed and the original stuff put right back on. I want power and I don't want to change everything over for a big block. I was just simply asking about a 440 small block. I have done lots of research. I was just asking about the motor and the next thing I know I am a "bird house builder."
