I could tell right away on my very first drive with my new 383 that the balance was MUCH improved. On mine, the crank with the flywheel was 15 grams out of balance and with the pressure plate bolted on was 38 grams out of balance.
Having it zero balanced with the pressure plate on made a VERY noticeable improvement, not only does it accelerate smoother but faster as well since it isn't fighting itself.
I had other people tell me before that it had a strange vibration feel to it but I never really noticed it. I just thought that was how 383s felt. Now I know.
Good luck with the new build.
