Yes, 318, 340, 360 are the same block and bolt pattern. The 383, 400, 440's have a different bolt pattern. Good Luck.

Also on this when you install the TC with the trans if it does virbrate very badly then the weight on that TC need to come off. It can be done while the trans is in the car, just leave the front cover of the trans off for easy access.
