Re: Harmonic balancer
Just be aware it may not be possible to fully internal balance the 478 crank. I went through with this situation on my 478. The balance shop put as much weight as possible in the crank and it still wasn't enough. they ended up welding weight to the flywheel and front stamped steel pulley(from the original 305E). I heard the only way to fully balance one of these 478 cranks is start with making a stroker out of it.
