'''The 454 engine ''' requires a flywheel with a weight at one spot on it. The small block flywheel for 350 engine is neutral balanced , will not work on the 454 correctly. | '''The 454 engine ''' requires a flywheel with a weight at one spot on it.

| − | They also make two different flywheels for the 454 a light weight and a heavy weight. | + | They also make two different flywheels for the 454 a light weight and a heavy weight. Most people run the heavy weight sometimes the light flywheel people has found will have a slight vibration in it. depending what year your 454. But either one will bolt up. |
Pioneer makes an add on weight plate to fix the problem. I know it works on auto trans, not sure of Manual trans fit. Had a friend do the same thing years ago. Made a great paint shaker. | Pioneer makes an add on weight plate to fix the problem. I know it works on auto trans, not sure of Manual trans fit. Had a friend do the same thing years ago.
