RE: Internally balanced 428 Revisited
By Mel Clark - 08/24/2001 8:28:36 PM; IP 64.12.101.172
Okay, I have to agree as I have checked a little deeper and Ford clearly recommends the use of the 428 SCJ crank, vibration dampner and flywheel for stroking the 390 to 410 CID. It might not have been correct but, when I built my engines I had them balanced internally as I would sometimes change transmissions from auto to manual and then I could use my heavy or light flywheel if running the 4 speed. A friend ran a balancing shop so I had several dampners and flywheels zero balanced. I could use them on any engine I was using at the time. I used the 410 Mercury crankshaft in my engines as I mistakenly believed they were internally balanced. My friend never told me of any difficulty in balancing these assemblies, so I continued to believe they were internally balanced. I'M sorry if I misled anyone, as I really get tweeked when I'm given incorrect info. Ford also says to use the capscrew 428 SCJ rods when building the stroker. Apparently this is so it is to eliminate the need to rebalance the engine.
