Re: Power steering pump bracket not fitting
A larger balancer will absorb more vibration. You may want to check with a more qualified engine person, but it has been done many times. You might consider a new aftermarket balancer, of the smaller diameter. If the engine was a 400 (externally balanced) you could not swap the balancers.
