A 400 type balancer such as this will be required for any 383 that is externally balanced. If your 383 is internally balanced it will require a 350 balancer.

This harmonic balancer is 8” and designed specifically for the Small block 400 which is externally balanced and cannot Be used on a 350 internally balanced engine. We do offer an 8” balancer for the 350 internal balanced engine under part number 91015357. Care needs to be taken for correct match up of the balancer to the engine or severe vibration and internal damage will occur.
