7 1/4" info
I think 71/4 rears are a gernade with the pin pulled. I have one in my 67 340 barracuda and am going to replace it as soon as I have the funds. Build your self a nice 8/14, that will last behind a 318. The difference between a 276 gear and a 355 is night and day. You wont be able to stop smiling!
