Harmonic balancer question - 05/05/13 04:02 AM

I have an internally balanced 408 and I want to upgrade to an aftermarket balancer. Should a new balancer just "plug n play" or do I have to have all the motor guts balanced again to match the new balancer?

thanks

Just plug-it-in ... but BE SURE that the HB is not for the ext bal.

It is ALMOST plug and play , aftermarket balancers should be sized to the crank snout , I'm sure it will come with an instruction sheet saying so.

Get a measuremnt of the snout of the crank or just take your old balancer to the local engine shop and they can measure the old and hone out the new .
